What is a COB LED – (Chip On Board LED Lights)

What is a COB LED?

The lighting industry is moving at a fast pace with continual new developments which are helping find solutions for many of our lighting needs. If you are wondering: “What is a COB LED?” then maybe we can help you understand.

What is a COB LED Light?

Chip on board (COB) LEDs are relatively new on the market, but despite their brief history, they offer many benefits when compared to the standard options. The first lights which can be considered similar to COB packages made their first appearance at the beginning of the 21st century and are the SMD LED packages. The COB light as we know it now first became available in 2007 and was met with skepticism because of the small packaging which contained so much power.

Sometimes they are called “fried eggs” because when not lit they resemble them. This is because of the yellow phosphor circle which is mounted on a white board.

Multiple LED chips are bonded by the manufacturer onto a substrate to form a single module called a COB LED. Typically nine or more LED chips are used and they are mounted in such a way as to offer the highest potential of lighting possible. When a COB LED package is lit, it has the effect of a lighting panel as opposed to looking like multiple individual lights.

What are the benefits of COB LEDs?

The lumen output per square inch for a COB LED is greatly increased in efficiency because of the multi-chip packaging. The reason for this is that the globe with LED diode chips has far more light sources covering the same are of a traditional LED. In COB LEDs, the viewing angle is increased and the loss of light is decreased since the lenses and other traditional LED packaging components are eliminated.

Since fewer components are required per LED chip to function correctly, the multiple diodes are housed within the COB LED with a single circuit and two contacts which energize them.

The greatest advantage because of the reduced components and the elimination of the traditional LED chip structure package is the reduction of heat generated by each LED chip. The operational temperature of the COB LED is also lowered because of the calcium/aluminum substrate which is often coupled to an external heat sink because it is a higher efficiency heat transfer medium. In order for a COB to be used at its full potential, care must be taken when choosing a heat sink. It must be capable of dissipating the heat generated so that the COB LED will work at increased efficiency and with lower failure rates.

The fact that spot soldering of the individual LED diode chips is not necessary, since mounting is done directly onto the substrate, is another reason why COB LEDs have reduced failure rates.

The advantages in short:


High-Intensity at short distances

Simplicity of design

High-uniformity at close working distances

Increased life, stability and reliability

What are the disadvantages of COB LEDs?

They cannot be used to create color changing bulbs or lights because of their limited contacts and circuit. So they are only efficient in single color applications.

Where are COB LEDs used?

The COB LED allows for heavy-duty applications, something which could not be done with LEDs.

There are a wide range of applications possible for COB LEDs and they could be used for higher output general lighting. However, their primary application would be as solid-state lighting (SSL) by replacing metal-halide lams. These are used for high-bay lighting, street lights, high-output track lights, and down-lights and are used in theatres and as grow lights.

In smaller applications we see COB chips in the flash of mobile phones and a point-and-shoot camera.



In conclusion

Almost every light source can be replaced with COB LED. They are the latest and most advanced technology in lighting existing on the market today. They are available in anything from a few hundred lumens to 30,000 lumens and can go up to 200 watts.

COB LEDS have proven to be a major step in LED lighting technology and have increased the capabilities of the power that can be included in the same size as an ordinary LED packaging. Their availability for all kinds of lighting situations has been increased by manufacturers who have produced a wide range of options for consumers to choose from.

What is a Xenon Bulb – Are they really worth it??

Some of you may ask yourselves: “What is a xenon bulb?”

Xenon bulbs are most commonly known for their use in the automobile industry, specifically for headlights. They are however, energy efficient and can also be used for home lighting and in flashlights, they are especially great for areas that need to be well lit.


What is a Xenon bulb

What is a Xenon Bulb?

Named after the gas that they are filled with, xenon bulbs are a form of incandescent lighting. The xenon gas extends the life of the tungsten filament, and both are encased within a globe of high melting-point glass.


Why add gas?

Regular incandescent light bulbs develop vacuums within their glass as air oxidizes the glowing tungsten filament. When an inert gas, like xenon or halogen, is added it slows down this process and the life of the bulb is prolonged. That is because the large gas molecules deflect the tungsten molecules. This slows their rate of evaporation and the filament keeps going for longer.

Xenon is an odorless and colorless gas and not only does it retard the filament evaporation, but also produces a bright-white light when electrified.


Xenon led bulb

Why consider a xenon bulb?

Both halogen and xenon are gases and when added to bulbs they work more efficiently than regular incandescent globes. Xenon though, is by far the more expensive of the two gases.

When compared to halogen bulbs, xenon bulbs last five times longer. In commercial bulbs halogen gives 1,000 hours use, whereas xenon anything from 8,000 to 20,000 hours. In the home environment they last about 3,000 to 5,000 hours, and sometimes even more.

Where can you use xenon lamps?

  • Automotive lighting
  • Portable flashlights
  • Work lights
  • Under cabinet lighting
  • Accent lighting
  • Recessed lighting
  • Task lights
  • Desk lamps
  • Artwork lighting

Benefits of using xenon bulbs


  •  Available in clear and frosted glass options according to your preference.
  • They have a better and warmer light that is more pleasant to the eye than that of halogen bulbs, even though they both have a similar color rendering index (CRI).
  • When they burn they don’t emit the same amount of heat as halogen bulbs, helping to keep the temperatures in the areas lit cooler and save energy.
  • Xenon gas requires less heat to produce light and saves on electricity.
  • Halogen light bulbs will have a greatly reduced light expectancy if touched directly on the bulb with bare hands, whereas xenon bulbs have no such problem.
  • There is no danger of having curtains and upholstery that are near the lights fade. The reason for this is that they emit minimal UV rays.
  • There is no danger of pressure building.
  • For those living in areas with unstable voltages with many dips and spikes, xenon bulbs will have a longer lifespan than other light bulbs, especially fluorescents.
  • Xenon lights can be used with standard light dimmers (unlike LEDs and CFLs which need the dimmer to be compatible with light bulbs that are also dimmable), making then energy efficient and giving you various lighting options for your living spaces.


You can use xenon lighting where you would have previously used incandescent or halogen bulbs.

Just remember to ensure:

  • That they have the same wattage and voltage
  • The lamp envelope or glass should be the same shape and size
  • Lastly, the lamps should have the same type of base e.g. bipin, festoon, wedge and so on.


Xenon energy saving


Recycling and the environment


Besides being more energy efficient than halogen and incandescent, xenon light bulbs are also much easier to dispose of especially when compared to CFLs. All types of light bulbs must be recycled, while CFLs need to be handled carefully because they contain mercury.

Xenon bulbs don’t contain mercury and if one breaks you won’t be exposed to any harmful toxins, whereas if a CFL breaks you must protect your hands by wearing gloves and put on a face mask to prevent breathing in the dust. The broken pieces must be placed in a sealed container and taken to a CFL recycling center. Also turn off the cooling or heating system in your home or office for at least 15 minutes.

In Europe many countries are phasing out Halogen bulbs due to their inefficiency, and incandescent bulbs are almost obsolete. LEDs are taking over the global market because they are the most energy efficient and environmentally friendly.

So, LEDs are the winners since they are 90% more efficient than standard bulbs and xenon bulbs, which have very few downsides, come in second.

They offer an optimal balance of candela and lumens and the longest regulated run times.

They are typically used for day-to-day industrial use, law enforcement; general contracting work and for vehicle maintenance.


⦁ High Lumen (HL) Series

These give maximum illumination from a high lumen beam and a good level of candela

They provide full situational awareness because of their extraordinary delivery of bright light in a wide beam pattern.

They are perfect for lighting up smaller areas, where a lot of concentrated light is needed.

They don’t have a long reach.

Typical uses include searching a dark alley, lighting a campsite, vehicle stop, and search patrols and scene illumination.

They are usually small enough to fit in a pocket.

⦁ High Performance, High Lumen (HPL) Series

Because of their high-candela beam these are a perfect choice for down-range applications which require optimal beam distances.

These flashlights have enhanced lumen output and deliver long-range lighting.

Their bright beam is peripheral and they throw more light on a target from a distance.

Typical uses include search and rescue missions, down-range illumination, inspecting utility lines from ground level and to light up a dark alley all the way down.


Disposable Battery Versus Rechargeable

⦁ Disposable

Both alkaline and lithium batteries have a long storage life of between 7 and 10 years. Their running costs are higher than those of rechargeable batteries and they don’t offer very bright lights. Lithium batteries are the more costly of the two.


⦁ Rechargeable

Rechargeable flashlights are better suited for frequent use. They use either nickel metal hydride (NiMH) or lithium-ion batteries. These flashlights might cost a little more to purchase but offer low operating costs.


⦁ Rechargeable 18650 USB

The lithium-ion 18650 battery is rechargeable on a USB port. The initial purchase price might be higher, but the running costs over the rest of the life of the flashlight are low.

>For a list of my best 18650 Li-ion batteries please click here<

Know the Bulb Types

Lumens of bulbs are a measurement of the total output of a bulb, whereas in a LED it is the measurement of all the light inside the angle of the beam. Cadela refers to the measure of the brightest spot in a focused beam.

Today’s flashlights depend on LED bulbs to produce light. This new technology offers cost efficiency and long life. LEDs offer flexibility and you can adjust the output and beam pattern according to your needs. Streamlight offers a choice of the following bulbs:

⦁ LEDs or Light Emitting Diodes – They offer up to 100,000 hours of light so don’t need replacement. They can run for longer periods on less power and are available in various colors, including Ultraviolet. At Streamlight they use some of their engineering technology, including a reflector, to increase the brightness and create an intense beam of light.

“Chip on Board” (COB) LED – Nine or more multiple LED chips are used together as one lighting module placed directly on a circuit board. When lit up the lights don’t show as individual lights, but look like a lighting panel.

⦁ Combination LED/COB LED – The combination of LED and COB LED offers intense brightness for long distance and flood beam for up close. This is a multi-function light that offers flexibility.

UV Flashlight – Black Light Flashlight – More Then Meets The Eye

I’m sure you have heard of the term UV light and/or black light before but what is it and what purpose does it serve? Well a UV flashlight or light and a Black Light Flashlight or light can be used in forensic science, money counterfeit detection and medicine to include a few. So keep reading and find out if a UV flashlight or a Blacklight flashlight is what you’re looking for??

UV Flashlight

What Is UV Light?

Ultraviolet (UV) is actually electromagnetic radiation, similar to that emitted by the Sun. Fact: only 10% of sunlight is actually UV radiation. UV light has a wavelength of between 10nm to 400nm; that is shorter than that of visible light, but longer than X-rays.

Black light is also known as UV-A light, Wood’s lamp or ultraviolet light and is a lamp that emits long-wave (UV-A) ultraviolet light. All of these lights work on the same principle and have very little visible light.

When a violet filter is included on the bulb or in a separate glass filter over the lamp, most of the visible light is blocked and only UV is allowed to filter through and the lamp will have a dim violet glow when lit. This type of lighting is called black light and will be designated as ‘BLB’, which stands for ‘black light blue’.

Lamps that do not have the filter have a blue color when operated and are identified with the ‘BL’ designation by the industry. These are used in lighting for insect traps.

Other than the Sun, UV light can be produced by electric arcs and specialized lights e.g. mercury-vapor lights, tanning lamps and black lights.

Uv Bug Zapper


What is a black light flashlight?

Black light flashlights produce a narrow spectral band of ultraviolet light which is just at the lower end of the spectrum of light visible to the human eye. The light it emits is not literally black, and even though the light appears weak, since the human eye cannot see most of it, it is actually quite a strong source of light.

All items that emit a bright glow when lit up by a UV or Black light flashlight actually contain phosphors. Phosphors are the name given to substances which can absorb energy and then emit it as a visible light, known as luminescence. There are natural occurring phosphors, e.g. found in our fingernails and teeth, or chemical phosphors such as those used in laundry detergents to assist making white clothes appear whiter.

Black Light Flashlight

Black lights have many practical uses and these include everything from entertainment, commercial, industrial, beauty and healthcare. When black lights are used in medicine, forensics and in some areas of science we often hear them referred to as a Wood’s lamp. This is because it is named after the inventor of the original Wood’s glass UV filter, Robert Williams Wood, an American physicist.

Medical Applications for black light and ultraviolet light

⦁ Dermatology – at a wavelength of 365nm the skin can be observed. The dermatologist can observe certain forms of fungal infections, which will fluoresce pink; bacterial infections, which will show up as coral red or yellow-green and certain acne causing bacteria which have an orange glow. Vitiligo, the condition associated with patchy loss of pigmentation, can also be detected and will appear as yellow-green or blue under the Wood’s lamp. Melanomas can also be detected like this.

⦁ Diagnostics – the ingestion of antifreeze can be picked up in the urine. Doctor’s are able to see if a patient has ethylene glycol poisoning due to the fact that its manufacturers commonly add fluorescein to it, which causes the patient’s urine to fluoresce under a black light. Porphyria can also be detected from the urine, which turns pink when illuminated.

⦁ Neonatal care – Known as the Bili light, with a range of 420-470nm, babies born with jaundice can be treated with phototherapy.


Safety of Using Black Light or UV Light

Black lights produce mostly long-wave UVA radiation, with low frequency and low energy and very low UVB radiation. Although UVA has been linked to the development of skin cancer in humans, it is still the safest of the three spectra of UV light. That is because UVA is low energy and does not cause sunburn, but it does cause damage to collagen fibers which then accelerates skin ageing and it also destroys vitamin A in the skin.

UVB and UVC directly cause DNA damage to the skin; while UVA is not as easily absorbed it can only cause problems with overexposure in situations like sun bed use. The retina of the eyes can also be damaged from long exposure, but the use of sunglasses with good quality UV protection is essential.

Black Light and UV Flashlight Uses

1. Counterfeit currency

The legal banknotes of many countries have fluorescent symbols on them that show up under black light. The rest of the paper used in printing money is of a different quality to commercially available papers. That means that counterfeit money will fluoresce all over under black light, whereas real currency will only fluoresce on where the specific symbols are.

$20 under UV Examination for Counterfit

2. Authenticate other documents

The identification cards, passports, driver’s licenses and other official documentation of some countries are produced with the same principles as those for counterfeit money and can be verified with the use of a black light flashlight.

3. Biological Stains

The applications here are very useful. Pet owners can often smell urine, vomit or feces from their pets, but cannot find them once they have dried on carpeting or furniture. A black light flashlight will quickly help solve the problem. One just needs to turn off the lights and turn on the flashlight, and the stains will glow until completely cleaned.

Detectives and policemen are finding black light flashlights very useful at crime scenes where they can pick up traces of various bodily fluids and crime scene tampering. The flashlights can also detect certain types of drugs. LSD fluoresces under black light.

4. Inspection for bed bugs

Bed bugs can spread disease and we need to regularly inspect our mattresses at home and when visiting hotel rooms to ensure that there is no infestation. Bed bugs hate light and it is very difficult to find them in the daylight. Black light flashlights will not find the bed bugs directly, but the bugs do leave a trail, which the light will pick up.

5. Hotel room inspections

When traveling we all fear coming across a hotel room that appears to be clean, but we can’t shake off the feeling, or the smell, that it actually is not what it appears to be.

The black light flashlight will help you to inspect the sheets and other bedding for stains that include urine, semen, saliva and beverage stains. It can also be used to check the shower, bathtub, sink and toilet for stains.

On arrival to any hotel room, all you have to do is draw the curtains and begin the inspection and if the cleanliness of the establishment is lacking call up for them to do the job properly.

6. Insect collectors

Photographers and collectors of insects and moths use various types of black light flashlights to attract the specimens at night.

7. Scorpion identification

For those of us living in areas with scorpions, we know that they are not easy to see at night, even with traditional flashlights. With UV flashlights and black light flashlights they are easy to spot.

Scorpion Under Black Lights

8. Geological inspections

Black light flashlights are very useful to budding geologists or professionals who like to explore the countryside and caves for interesting mineral formations.

9. Heating, ventilation and air conditioning repairs

Refrigeration and air conditioning systems can be difficult to maintain. Technicians find portable black light flashlights useful in detecting leaks within compressor and refrigerator pipes. They often inject fluorescent dye into the system which will then light up as it leaks from the pipes.

10. Construction sturdiness

Engineers working on metal structures apply fluorescent fluids to these and then inspect them with black light to ensure that there are no cracks or other weaknesses in them.

11. Entertainment venues and other security applications

When working in offices or living in spaces with other people there are often mix-ups with items such as pens, flashlights, clothing and other apparatus necessary for us to complete tasks or get about our daily lives. This can be prevented by using fluorescent marking pens to put our names on these. The invisible writing will only show up when lit under a black light.

Black light Clubbing

Many entertainment venues like clubs, theme parks and festivals often use a fluorescent rubber stamp on the wrist of attendees. This allows them to ensure that those who have paid can leave and re-enter while others do not get in without paying.

12. Inspecting old homes or used furniture

The purchase of older homes or used furniture can often be wrought with dangers of later finding things that are well hidden. Black light flashlights help detect stains on carpeting and furniture and detect old mold stains in bathrooms and kitchens.


UV and black light flashlights are practical to use and cover large areas, depending on the number of LED bulbs. Most are water and shock resistant and are economical to use, while also hardy against falls and bangs. When operating UV or black light flashlights they should not be looked at directly into the light and should not be shone into the eyes of others.

I will be updated this post with recommended products shortly so please bookmark it if needed and check back shortly.

li ion battery – lithium ion batteries – The Past And The Future

The lithium-ion batteries or Li-ion battery is rechargeable through the actions of lithium ions. These move from the negative electrode to the positive during discharge, and backwards again as they recharge.

As opposed to non-chargeable Li-ion batteries, which use metallic lithium, rechargeable ones use intercalated lithium compounds.

li-ion Phone and Power Pack


A Short History Of The Invention And Development Of The Li-ion Battery

The idea for the first Li-ion battery was proposed by Stanley Whittingham during the 1970s. At the time, the British scientist was working for Exxon and he used titanium sulfide and lithium metal as the electrodes. Titanium disulfide proved to be impractical, since it needed to be produced under completely sealed conditions, and the price of the raw materials was prohibitive.

Exxon discontinued the production of the battery because of this and also took into consideration that, when exposed to air, titanium disulfide reacts to form hydrogen sulfide compounds, which are toxic and have an unpleasant odor.

Since metallic lithium presented safety issues for use in batteries, research moved toward lithium only compounds that are capable of accepting and releasing lithium ions. Researchers worked at the development of electrode materials for lithium ion rechargeable batteries between 1973 and 1996 and their efforts were concentrated on two main trends. One was concentrated on graphite intercalation compounds through the field of electrochemistry, while the second was from the field of new nano-carbonaceous materials.

During the early 1980s, a polyacenic semi conductive material (PAS) was discovered by Tokio Yamabe, which was later improved by Shjzukuni Yata. Another development that helped the process was the discovery of conductive polymers, made by Professor Hideki Shiakawa and his team and then Alan MacDiarmid and Alan J. Heeger and their team developed the polyacetylene lithium ion battery.

A History Of The Commercial Production Of The Li-ion Battery

⦁ 1991 – the first commercial battery is released by Sony and Asahi Kasei

⦁ 1996 – Lithium iron phosphate (LFP) and other phosphor-olivines are proposed as positive electrode materials by John Goodenough, Akshaya Padhi and others.

⦁ 2001 – Lithium nickel manganese cobalt oxide (NMC) is patented by Zhonghua Lu and Jeff Dahn. This material offers safety and energy density improvements to the lithium cobalt oxide, widely used until then.

⦁ 2002 – By doping the materials for lithium batteries with aluminium, niobium and zirconium, Yet-Ming Chiang and his team at MIT, manage to increase their performance substantially and cause an extensive debate among scientists.

⦁ 2004 – With the rapid growth of the Li-ion battery market, a patent infringement battle breaks out between Chiang and Goodenough. In the meantime Chiang discovers that by utilizing nano lithium iron (II) phosphate particles, the particle density decreases hundredfold, and improves the capacity and performance of the battery through an increased positive electrode surface.

⦁ 2011 – Rechargeable batteries make up for 66% of all battery sales in Japan.

⦁ 2012 – The IEEE Medal for Environmental and Safety Technologies goes to John Goodenough, Rachid Yazami and Akira Yoshino for developing the lithium ion battery.

⦁ 2014 – Amprius Corp. uses a silicon anode which increases the capacity of the batteries by 20% to 650 Wh/L.

John Goodenough, Yoshio Nishi, Rachid Yazami and Akira Yoshino are all recognized for their pioneering efforts in the field by The National Academy of Engineering.

By 2016, global lithium-ion battery production capacity was at 28 gigawatt-hours, of which, 16.4GWh was in China.

Li ion Powered Car


Uses For The Li-ion Batteries

There are other rechargeable batteries on the market, namely, the NiCd battery, but even though these are cheaper, they cannot operate over a wider temperature range, nor do they have higher energy densities. Lithium batteries have a protective circuit to limit peak voltage.

For example, each lithium-ion cell of a laptop computer battery pack will contain:

⦁ temperature sensor

⦁ voltage regulator circuit

⦁ charge-status monitor

⦁ mains connector

The design of these components is such, that they minimize the risks of short-circuits by monitoring the charge-state and current flow, keep a record of the latest, full-charge capacity and monitor the temperature.

Due to their lightweight, high energy density power sources, Li-ion batteries can be used for a whole range of devices. When used in larger devices, it is more effective to connect many small batteries in a parallel circuit than to have one large single battery.

Portable devices that use Li-ion batteries include: Mobile phones, smartphones, laptops, tablets, digital cameras, electronic cigarettes, torches and portable game consoles.

Power tools that use the batteries include: All cordless tools and garden equipment, including drills, sanders saws, hedge trimmers and lawnmowers.

Modes of transport that use the batteries include: Electric cars, hybrid cars, electric motorcycles and scooters, electric bicycles, electric wheelchairs, electric golf caddies, radio-controlled model cars and aircraft, aircraft and even the Curiosity rover sent to Mars.

Telecommunications service providers use a type of secondary non-aqueous lithium battery to provide reliable backup power for their equipment; while Li-ion batteries with specific technical criteria can be use in outside location huts and enclosures. Here the users have to be made aware of the hazardous material information and have to meet the correct regulatory requirements and fire-fighting procedures.

Battery Discharge Rates And Life

Li-ion batteries self discharge at a rate of 1.5 -2% per month when not connected. This does increase when various other factors come into play, which include higher temperatures, state of charge and age of the battery.

Capacity loss is affected by inactive storage and by a defined number of full charge-discharge cycles which affect the lifespan of the battery.

The average lifetime of a Li-ion battery consists of 1000 cycles, and usually it is specified for no more than 500 cycles. That means that the batteries of hand held devices like mobile phones can be expected to last for approximately three years. Batteries based on carbon anodes can offer more than 10,000 cycles.

The voltage of the battery gradually diminishes as it discharges, but it stops discharging at a set level of depletion of 2.4 – 2.9 V/cell (this depends on the chemical composition), which is the protection circuit’s low-voltage threshold. At this level it stops discharging until recharged.

These rates may not be fully accurate because there may be variations depending on full depth of discharge/recharge, which can affect the life of the battery and once again, temperatures also play a role.

With use, Li-ion batteries degrade progressively and they have a reduced capacity, cycle life and safety because of chemical changes to the electrodes. This degradation is strongly related to temperature, with 25 degrees being the ideal storage temperature. Anything over or below that increases the degradation and even charging elevates temperatures. Poor ventilation in some devices or apparatus also increases the temperature.

Safe Usage Of Li-ion Batteries

Thermal runaway and cell rupture may occur in overheated or overcharged Li-ion batteries. In order to reduce the risk of this happening, many lithium batteries have a safety feature that disconnects them when their voltage surpasses the safety range of 3-4.2 V per cell or if they are overcharged or discharged.

It is also important that they are not used outside their recommended voltage range set by the manufacturer, as the batteries will age prematurely and the reactive components within the cell pose safety risks. Some types of lithium batteries are not safe to charge at temperatures of 0° and below.

Since Li-ion batteries require many safety features (which cannot be applied to all types of cells) they are more expensive, and contaminants inside their cells may decrease their safety. The presence of the potentially hazardous pressurized flammable liquid electrolytes in the batteries, require strict manufacturing regulations.

There have been a few aviation incidents and crashes caused by lithium-ion battery fires, where batteries have spontaneously ignited.

Li-ion Batteries And The Environment

Lithium batteries contain iron, nickel and cobalt and are considered safer to discard than other types which contain toxic metals like lead or cadmium. The metals they contain can be recycled but at a larger cost than mining these metals, so most end up in landfills or incinerators.

Cobalt is the most expensive metal used in lithium battery manufacture, and lithium iron phosphate is the cheapest, but with a danger of future shortages. Lithium extraction does impact the environment through water pollution and recycling could help prevent this and future shortages. Lithium is mined in the Americas, Asia, South Africa and China.

Raw Cobalt

Nickel and cobalt need a solvent in their manufacturing process which does present environmental and health hazards.

Each one kg of Li-ion battery production takes the energy equivalent of 1.6 kg of oil.

Over the years there have been huge recalls of various batteries by companies such as Dell, Apple, Lenovo, Toshiba and many others. Many restrictions have also been imposed to transporting or flying with them. Most devices can be transported in checked baggage, but spare batteries may only be transported in carry-on baggage and should be protected against short circuiting. It is estimated that more than a billion lithium batteries are flown each year.

Ongoing research will see improved batteries in the years to come, with better power density, battery life, recharge time, cost and safety.

Camping Lantern Reviews – (LED Lights and Lanterns for Camping)

The need for a camping lantern has always been with us for 100’s if not 1000s of years but now with more products on offer then even before you need a good camping lantern review,  there is also more things to consider, when looking to buy a new camping lantern it is important to be aware of what to look out for in order to avoid a bad purchase or something that’s not suitable for your needs at all. So, when you next intend on buying a camping light, look out for the following;


Camping Lantern review


1) The Weight

A good camping light need to be as light as possible. This is because camping lights are more often than not carried from one place to another when in use. If a camping light is weighty, it becomes strenuous moving it from one place to another when in use, and as such, exerts effort. And no one wants to be stressed out by a “camping light,” and with time, the lamp is abandoned thereby defeating the purpose of its purchase. Therefore, a lighter light would be more effective in serving its purpose over a heavy light.

2) The Size or portability

Camp light needs to be portable. The size of a battery powered led light to a large extent, determines its portability. A lamp with an outrageous size would turn out to be more of a liability than an asset. This is because of the impending difficulty in carrying it from one place to another. An extremely large camp light cannot be easily carried because of its size. Thereby defeating its portability which makes it less effective and more of a burden.

3) Battery Life

This is one of the most important factors to consider when looking to buy a new camping light. A lights battery life depends largely on the size of its battery but the speed in which a battery charge is depleted can depend heavy on the output of the light so if the light has only one setting and its a high light setting your going to deplete the battery effectively if you can use the light on a lower setting. So make sure your chosen light has a good battery and has different light output settings so you can use its battery efficiently.

4) Quality of material used in the production

Checking out for good, solid and long-lasting material use in the production of camp lights is very essential. This is because there is a very high possibility that you’re camping light may fall or slip out of your while in use. A camping light made out of low-quality material is likely to shatter into pieces once it falls and hits the ground with a high chance of the light being unusable after this. Whereas a good quality camping light would survive several falls. However, it is important to handle you’re camping light with care.

5) Brightness

A good camping light must be radiant. A camping light that has a low light output should not be consider in most cases. This is because one of the major purposes of purchasing a camping light is to keep your camp site illuminated, help you navigate a dark route and aid easy vision if you intend to read a book, cook, get dressed and so on at night before sleeping. If a camping light is not radiant enough to help you accomplish all of these, then it should not be considered.

What Is The Best Flashlight – You Need To See This

What Is The Best Flashlight Money Can Buy?

Since the reasons for which we need flashlights are relatively different, here are a few things to consider before choosing what is the best flashlight to buy.

Surefire Tactician

Flashlight Types

We know that there are quite a number of flashlight options to pick from whenever you check your online stores; however, it is worthwhile to know that flashlights can be categorized into different types.

Tactical Flashlights

These flashlights are basically created to suit military and paramilitary purposes. Tactical flashlights are military grade flashlights which are somewhat different from the ordinary flashlight for home use. These type of flashlights are usually used together with firearms to help with target-identification by allowing the user to aim and illuminate a target simultaneously. Tactical flashlights can as well be hand-held or handled without having to mount them on a weapon.

Common features of the tactical flashlights include their portability due to lightweight construction, very high-intensity illumination, long-lasting battery capacity, shock resistance, and multiple light settings, produced with weapons-grade aluminum and so on.

LED Flashlights

Flashlights are fitted with incandescent light bulbs from which light is emitted. However, the incandescent light bulb is gradually being replaced with light-emitting diode (LED). LED bulbs generally have a longer lifespan than the incandescent bulbs and are also more efficient than the incandescent light bulbs.

Most flashlights today make use of the LED bulbs and are thus referred to as LED flashlights.

standing on mountain with flashlight

Flashlights can also be categorized according to the following:

⦁ Lumen- this is simply the unit for measuring light. One lumen simply put is like a unit of light in a dark room, hence the higher the number of lumens, the brighter the light. LED flashlights have from 20 to 200 lumens although, some high illumination flashlights, as well as ultra flashlights, can generate over 550 lumens. Ultra bright flashlights like those referred to as portable sun can generate over thousands of lumen. Some amounting to about 8,000 lumens. The average or mid-range flashlights produce about 300 lumens maximum.

⦁ Water resistance- water resistant flashlights can be categorized into IPX4, IPX7, or IPX8. Flashlights classified under IPX4 are the most common as it is the average water resistance rating. These flashlights can be used effectively in adverse weather conditions although they do not possess much water resistant capability. IPX7 categories of flashlights can be submerged in water for a short period without damage. And the IPX8 can be submerged to certain depths underwater depending on the manufacturer’s product. This category is usually manufactured for the purpose of underwater exercises such as diving and underwater repairs.

⦁ Purpose- can classify your flashlights based on the purpose for which it is needed or used. Military flashlights as the name implies, are best suited for military purposes as well as tactical flashlights although tactical flashlights could be used for other purposes apart from military exercises and routines. Now your high-precision tactical flashlights might not be entirely effective for your other activities. The flashlights required for diving and underwater repairs, fishing, and hunting, camping and hiking all differ as these activities all have flashlights best suited for them.

Outdoor Solar Lights – For Style And Security

In the past lighting your outside space had always been such a hassle. You would have to choose where you wanted the light to go, dig a channel to run the cable to the lights or drill through brick and then wire them up to a power point. If you were unlucky you might even damage the cable with a spade or fork by accident.


Halogen Security Light

You can now have the style and security of outdoor lighting be it with or without motion detectors and none of that hassle, because you can buy outdoor solar lights that can work without mains wiring and recharge themselves with the power of the sun.

Why Go For Solar Outdoor Lights?

You can choose a light that turns on automatically at dusk, lights that can be manually turned on and off or wall mounted security lights that will turn on when motion is detected “like an unwanted guest”.

These light are so simple to install, being powered by the sun and storing the electrical charge in an internal battery, there are no cables to worry about and at the most will require a few holes in a wall for mounting. Just choose where suits you best and place them there.

Small Solar Light

If you are looking to cut cost on electricity bills, then installing solar powered lights across your yard and gardens will definitely save you some extra cash. Despite their capacity to turn the energy of the sun into electrical energy, outdoor solar lights are manufactured without intent to compromise the beauty of your yard.

These environmentally friendly and easy to maintain outdoor solar lights can come in some of the most beautiful and elegant designs.

While some especially the decorative lamps can be staked to the ground, security lights can be fitted to poles or mounted on walls surrounding the yard.

How Long Does A Solar Battery Last For?

With modern Li-Ion battery technology (also found in your smart phone, cordless drill, electric car to name a few) the battery can depending on size last up to and above 10 hours on a day’s charge. You don’t have to worry about replacing the batteries because they’re rechargeable, so you’re getting your free energy from the sun not from the main’s and not having to worry about replacing batteries. It’s a win / win combination.

Some Benefits Of Outdoor Solar Lights

Due to the variety in types and styles of outdoor solar lights, it is considerably easy to find lights matching your desire and required design. Imagine wanting to light up your yard or garden with Patio torches, Solar lamps like the Newhouse lighting solar flickering LED Tiki torches will give you that desired effect without you having to deal continually with the flames from Patio or Tiki torches.

The benefits of replacing your lighting with solar-powered lights are quite numerous. Solar lights are predominantly cost-effective and can save owners and users a considerable amount of money spent on maintenance and electricity bills.

Solar lights convert the energy from the sun into electrical energy; thus they are suitable for use even in places and environments lacking electricity. That is even places without electrical grids could be easily lit up with the aid of solar lights.
Solar lights range from household lights to decorative lights and even outdoor security lights.

Outdoor solar lights provide a much more convenient and less expensive way to keep the neighborhood lit up at night. Without recourse to electrical grids, entire streets can still be properly lit for drivers, pedestrians and overall security of an area.


Dark Road at Night


Some of the benefits of using solar energy based lightnings outdoors include;

  •  The reduction in the cost of electricity bills
  •  Their durability and easy to fix nature
  •  Solar lamps could be conveniently installed without the aid of expert individuals
  •  It reduces the dependence on fossil fuel
  •  They operate on clean and renewable energy
  •  There is no need for visible wires except in rare cases
  •  It does not in any way cause nor increase atmospheric pollution as no gas is emitted
  •  There is no reliance on electricity to power it
  •  It can be conveniently installed outside, either on a wall, pole or even staked to the ground
  • Works when the power is out!!– Because the light’s are not connected to your main’s the lights will work if there is a power cut
  • Maintenance is relatively cheap; and so on


How Bright Are Solar Outdoor Lights?

Outdoor solar light’s have a large variation in light output as decorative lights can have a low flame or glow effect but outdoor security light’s can have a massive light output, well over 1000 lumens

“See Link To Lumen Scale Here”

Of course, it depends on what you intend to use the light for so make sure you chose a light output that suits your requirement.

Solar Down Lights

Down lights placed on the outside of your house or garage can really make your home stand out with bright warmth and of course add security, they also look fantastic in my option.


What Are The Downsides Of Solar Lights?

The main downside to a LED solar light compared to a conventional halogen bulb mains light are the LED lights can’t be replaced like a normal bulb. LED bulbs do last on average 10 x longer then a normal bulb so you are going to get years and years of use out of the light before this is an issue. In general outdoor electrical equipment, due to the exposure to the element’s, fails after a few years anyway.

The other thing to be aware of is if the solar light has a dirty solar panel the battery will not get a full charge and the light might not manage to stay light all night if you have it on a constantly light setting.

But overall the advantages of a solar outdoor light easily outweigh the negatives.

Types Of Outdoor Solar Lights

There are a variety of ways in which outdoor solar lights can be categorized; however, in this article what we consider is the purpose for the lights. Installing outdoor solar lights could be for security, decoration and/or beautification or merely illumination.

⦁ Garden and pathway lamps- outdoor lights falling under this category are mainly for the purpose of aesthetic purposes. Garden lights offer a different kind of glow perfect for beautifying and adding glamour to a yard. These type of lights are not usually as bright as the security lights or those built merely for illumination. Pathway lamps although similar to the garden lamps can be staked into the ground or fitted on poles along a path to illuminate such path as well as beautify it.

⦁ Street lamps- these solar powered lights provide drivers as well as pedestrians, the illumination necessary for whatever activities geared towards nightfall. It also serves a sort of security purpose by discouraging illicit activities due to the bright illumination it provides.

⦁ Security lights- security lights are fitted with the sole purpose of providing security to a yard or building. They could be mounted on walls, flagpoles, or even hung from structures. Most recent solar powered security lights are also fitted with motion-sensors to further deter intruders.

LED Flashlights – How They Evolved

Humans have always needed a portable light source and they initially carried wooden torches, candles, oil lamps and kerosene lamps around with them at night. The need to emulate the sun at night has not changed in humans for millennia; we need light to prevent falling over objects, falling into uneven surfaces and to protect us from stepping onto dangerous creatures. Since these always used the flame as a source of light, they were often dangerous.

Flame Torch

Why We Need Lights

We are not nocturnal creatures and our eyes cannot adapt to the dark. From the moment we managed to harness the power of light, human advancement took the greatest leap ever and gave us civilization as we know it today.

The end of the 19th century there was an exciting time with many inventions. The incandescent electric light bulb and the dry battery were two of these that solved the problem of carrying a live flame everywhere at night.

Some of the many inventors who left their mark in the history of lighting were Thomas Edison, Nikola Tesla, William Sawyer, Albon Man and Joseph Swan. The light bulb was developed, patented and commercialized and electric lighting was installed in cities around the world, making life easier for all its population.

Edison Electric Light


The safe portable light came into being in 1898. The invention of the flashlight cannot be credited to one single person. It evolved out of a discordant series of events and many people independently working on various ideas which we will examine, below to see how we finally got to the LED flashlight.

A Historic Breakdown

Daniel Mcfarlan Moore created the first commercial arc tube lamp in 1898. The idea behind the lamp was very similar to the fluorescent lamp that we know today, which sent an electrical current through an inert gas to create light.

David Misell, a British inventor, applied for and was awarded a U.S. patent N0.617592 in 1898. It was for a simple paper and fiber tube lantern which was powered by the world’s first dry-cell battery. This battery was safer and more reliable than an invention two years prior to that. Rather than having a liquid electrolyte in its casing it had a dry paste. Conrad Hubert was his boss and owner of American Electrical Novelty and Manufacturing Company and Misell assigned the manufacture of these torches to him. This was the beginning of the first ever mass produced hand torches: the Ever Ready electric hand torches.

Ever Ready Flashlight Ad

The Ever Ready trademark started to appear on the end cap of flashlights for the first time in 1902. The incandescent lamps were improved as bulb makers started using better quality filaments. These were more consistent, lasted longer and were much cheaper making the flash light a popular item among consumers.

American Ever Ready Company was born in 1905, out of the reorganization of American Electrical Novelty and Manufacturing Company by its owner Conrad Hubert.

Ever Ready’s new tungsten filament bulbs were introduced in 1910, and the popularity of their flashlights continued to grow in popularity. By that time they were the top name among flashlight manufacturers in the world.

A Real Big Hit

By 1922 there were 10 million users of flashlights and there were several styles available. The choices were the classic cylindrical, the standing lantern, reflector or flood and the pocket size. All were extremely popular.

Richard Thayer and George Inman invented the modern fluorescent lamp in 1934.

Ever Ready shortened their trademark to EverReady in 1937 and introduced the first pre-focused bulb. This was more efficient as it was a pre-assembled bulb and reflector and required less power but produced the same amount of light.

Vintage Flashlight

Energizer became the new trading name of EverReady during the 1950s. Their batteries were still using the EverReady trademark.

James R. Biard and Garry Pittman were working on developing semiconductors in 1961, when they accidentally invented the first Light Emitting Diode (LED).

Texas Instruments began selling the first LED to IBM in 1962. The cost was $130 each and they were used to replace tungsten bulbs used in punch-card readers.

Introduction Of Rechargeable Flashlights

In 1967 the first EverReady rechargeable flashlight was introduced by Energizer. This allowed for the flashlight to be recharged doing away with the complete dependency on batteries.

The first fluorescent lantern was introduced in 1968 by Energizer. This was more efficient and lasted longer than the filament bulbs.

Energizer again came up with a first – a water resistant flashlight – which was introduced in 1970. The flashlight came with a push-button switch – the first ever- and the switch had lifetime warranty.

In Come Maglite

Tony Magilca had started a small shop called Mag Instrument in California in the 1950s with a capital of $125. In 1974 the business became Mag Instrument Inc and in 1979 they introduced the first Maglite flashlight.

Mag-Lite Flashlight

The 1980s saw huge strides in the design and technology of flashlights. The pocket-sized flashlight was born and so was the halogen-bulb flashlight, which emitted a brighter light.

The LED flashlight was only introduced 40 years after the invention of LED. The initial bulbs were not suitable for use in flashlights. Only in 1999 did a California based company called Lumineds introduce the Luxeon LED bulb which was brighter, more efficient, lasted longer and could be smaller than the previous types of bulbs used in flashlights. This LED bulb was the most important development in the many years since the invention of the flashlight. Every watt fed into a LED produces 100 lumens, ten times less than an incandescent bulb needs to produce the same light.

The First LED Flashlight

The first LED flashlight was designed in 2001 by Luxeon and was the Arc LS.

LEDs are now the most popular bulbs for flashlights as they are dependable, cheap to manufacture and are sold at a good price. LED flashlights today can produce a vast range of outputs from an equally wide variety of batteries, accumulators and super- capacitors. The battery life of a LED flashlight will last much longer and they are less fragile than other lamps. With a different spectrum of light compared to incandescent globes they can also be made in several ranges of color temperature and color rendering index. The LED bulb might never need to be changed because they do not burn out easily.

Colored LED flashlights are used in certain jobs which require signaling, special inspection tasks, forensics examiners and are used to track blood trails by hunters and game rangers. The color of these LED bulbs depends on the task it is needed for, but red is used to preserve dark adaption of vision, ultraviolet for inspection lights which can detect gases and leakages in machinery such as air conditioners. Ultraviolet is also used to examine paper currencies or checking ticket holders and for UV-fluorescent marks on laundry. LED flashlight can be used in conjunction with night time devices.

LED Special Requirements

Since LEDs must have a limited current through the diodes LED flashlights using one or two disposable batteries need a boost converter to provide the higher voltage required by white light which needs 3.4 volts to function. Two batteries usually will only reach about 3 volts. Those with three or more dry cell batteries may only use a resistor to limit current. Other LED flashlights electronically regulate current through the LEDs and stabilize light output as the batteries discharge.

The color temperature of the older flashlights rapidly decline and become redder and less visible as their batteries discharged but with LEDs it remains constant regardless of input voltage or current.

Some LED flashlights come with user-selectable settings which help the user regulate the light according to the task it is needed for. These can be adjusted for anything from reading at a lower light and a stronger light for looking for smaller objects in dark areas. This was not something that could be achieved with older flashlights.


LED Benefits

LED flashlights produce heat as well as light and the life of an LED decreases with temperature. The need to avoid heat dissipation for the LED requires that smaller high-powered LED flashlights have high heat conductivity bodies which could be made from aluminium or other conductors, and they also have reflectors so that they don’t become warm during use.

They come in the tiniest of shapes which can fit in pockets; they are made in key rings, pens, used as headlamps on helmets used by builders, miners and even hunters. Light outputs can vary according to the size of the batteries operating them. Keychain LEDs run on button batteries and similarly a single 5mm LED may only produce a couple of lumens. A small LED flashlight operating on one AA battery can emit 100 lumens and the most powerful LED flashlights produce more than 32,000 lumens and may be fitted with multiple LEDs.


Since man carried those first wooden torches until today flashlights have been a necessity for safety and moving about. As far as we have progressed we all still need to be able to move around safely in the dark, and the LED flashlight is making this easier than ever before with its bright light and smaller sizes.
