Batteryless Flashlights, Or Sometimes Known As Forever Flashlights

by Tyson J Stevenson

As the name suggests, a Batteryless Flashlight works without any need of batteries. One can also call it the forever flashlight. These light emmitting tools are also known as Batteryless Torches in countries from a British background. These types of torches need to be shaken back and forth for few seconds and they will give light for many minutes, sometimes even hours. The main features of these Batteryless Flashlights are


1) Never needs any batteries or bulbs
2) Now with magnet and tether strap
3) Compact and water resistant.


Perhaps the biggest feature is that these torches are rechargeable at any time.


· Magnetic (Batteryless) Flashlights


The product Magnetic (Batteryless) Flashlight is the newest technology in the industry. One just has to shake the torch for 60 seconds and you will get up to 2 hours of light from this appliance. These flashlights have three super bright LEDs which emit bluish white light that helps us in viewing clearly in the dark.


There is a high field strength magnet inside these flashlights, that slides back and forth inside a coil of copper wire, as we shake it to generate electric power. This power then gets stored in a small capacitor. The stored energy in the capacitor then powers the high brightness white-light LEDs.

It is prudent to turn the switch off at the time of shaking the flashlights for charging. If the switch is not turned off then pulse with the power spikes coming from the coil can be seen in the LEDs. The operating switch of these no battery flashlights is durable and intrinsically safe. These torches lights are very light in weight and are completely designed to be waterproof. They are also fully portable.


· Dynamo type No Battery Flashlights


Another type of (without batteries) flashlights is the dynamo type. These were the oldest technology among the battery-less flashlights. These types of torches have little fold-out cranks and we need to wind on for a while so that we can use the light again. In Dynamo type flashlights, by winding the cranks for a few minutes, a sector gear starts to move causing a tiny pinion gear to spin which drives a PM dynamo.

The dynamo generates electrical energy which is used to light the LEDs in the batteryless flashlights. For years there have been dynamo types flashlights around that the world those work by squeezing a lever handle. Dynamo type battery free flashlights are more reliable than the ordinary battery lights.


· Batteryless Flashlights review

The No Battery flash-lights are mainly used for emergency purpose. These flash-lights sometimes come with built in FM radio. The main advantage of this Batteryless flashlight is that they are absolutely maintenance free. These flashlights can be stored for long periods of time without the worry of leaking batteries. In case of battery powered torches they often have their battery contacts loose & dbecome dysfunctional, but the batteryless flashlights don't go dead as you are miles away from home late at night.
The main disadvantage about these batteryless flashlights is that they are not as bright as most other battery powered ones, but that's a small price to pay as they are infinitely brighter than any other battery powered flashlights who's batteries are drained of energy or their bulbs are broken or burned out.

How To Reduce Your Expenses by Buying Rechargeable Flashlights

by Paul Duxbury

A great addition to any toolbox or kitchen drawer is a rechargeable Flashlight because it eliminates the problem of never having any replacement batteries when you need them!

There are various types of rechargeable flashlight available and it's worth considering what you want to use them for before going ahead and purchasing one. Sets including a rechargeable battery pack are readily available and include all types from the small hand held types, the heavy duty ones with handles, helmet lamps and angled lamps. These are great for heavy usage as it saves a packet on replacing batteries regularly. Some also allow for using ordinary batteries in an emergency, if you can't wait for or can't get to charge your rechargeable flashlight.


One of the other types of rechargeable flashlight available is those which do not use a battery and which can be manually charged. This manual charging is normally by shaking, squeezing or winding the flashlight. Most of these types take anything up to 90 seconds to charge and can provide up to around 45 minutes of light on each charge.

Generally the way you charge this type of flashlight is to shake it up and down for several seconds, or by squeezing a trigger a few times, or even by winding a handle. It's that simple that you can quite literally do it in the dark. This type of flashlight is ideal for having immediately at hand in case of emergencies such as blackouts, since charging them takes just a matter of seconds. Not having to leave them charging at the mains, or leaving batteries to leak inside means they are always readily available as long as you remember where you put it should the power suddenly go out of course!

In the medium to longer term rechargeable flashlights are extremely cost effective. In addition to never needing replacement batteries, most will run off LED bulbs instead of ordinary bulbs, and have a far greater lifespan. The LED bulb is highly durable and will last for anything up to 10,000 hours or more. Inevitably, this does makes the LED bulb slightly more expensive, however you can almost guarantee dropping it won't break it, and because they do not produce heat, they don't burn out.


Rechargeable flashlights are available to purchase from many hardware stores and literally thousands are listed online.

Flashlights As An Indispensable Tool

by Steve Vaile

In an age when even our cars are sending us e-mails about needing oil changes or spark plugs, something like the flashlight just doesn't really impress us. Much like it did for our grandparents, a flashlight just shines light and eats batteries like there's no tomorrow. You don't see any flashlights with digital LED readouts or Internet access--so what's the point? Even in this brave new world of wireless technology, the flashlight remains an indispensable tool.


At the end of it all, a flashlight simply produces illumination. That's it--no more and hopefully no less. Simple yet completely functional even in our technological age, the flashlight remains as needed as ever. Power outages remain a constant threat and Hurricane Katrina certainly taught everyone how useful a flashlight can really be. Getting the attention of helicopters, especially at night, is no easy feat for someone stranded on a roof. But give that person a flashlight and they will have no trouble getting the attention of people in a rescue helicopter.


Of course, Hurricane Katrina was a rare event and it is not every day that someone needs air lifted off of their roof. But even in the common power outages caused by blizzards or heavy storms, a flashlight is usually the first thing people go looking for. Candles may be great for producing ambient lighting in a room, but they are useless when it comes to helping you navigate through dark rooms. If they don't blow out when you're walking, they still don't produce enough light at your feet to avoid stubbing your tow or really getting hurt. A flashlight is the preferred tool when it comes to walking in dark conditions.

If power outages are the primary reason to keep a flashlight around the house, then flat tires make them indispensable in the car. While we would love to believe that some roadside assistance or AAA will save us immediately when we have a flat tire, the truth is that we can be waiting for hours before any help arrives. Even in this digital age, it sometimes is necessary to change a flat tire--at night. You need a flashlight just to be able to find the jacking point on the car, let along find the lug nuts lying on the ground after you take the tire off. Without a flashlight, just prepare to sit around and wait for the tow truck or roadside assistance tech--however many hours later that might be!

Since a flashlight is still a very necessary tool today and you want it to work when you need it, plan on buying a good one. Don't waste your time with a flashlight that has a plastic casing. Aluminum or metal alloy frames are the best and most durable. You will drop the flashlight from time to time so buy one with a solid frame so it can take the abuse and keep working. Also, make sure you buy a flashlight with a bright bulb and preferably a spare bulb stored somewhere on the frame. That way, you never have to worry about your flashlight failing you when you most need it.
