More Info About Flashlights

A flashlight (usually called a torch outside North America) is a hand-held electric-powered light source. Usually the light source is a small incandescent lightbulb or light-emitting diode (LED). Typical flashlight designs consist of the light source mounted in a parabolic or other shaped reflector, a transparent lens to protect the light source from damage and debris, a power source (typically electric batteries), and an electric power switch.
While most flashlights are hand-held, there are head or helmet-mounted flashlights designed for miners and campers and battery-powered lights for bicycles. Some flashlights are powered by hand-cranked dynamos or electromagnetic induction or are recharged by solar power.

The name flashlight is used mainly in the United States and Canada. In other English-speaking countries, the more common term is torch or electric torch.

In 1896, the first dry cell battery was invented. Unlike previous batteries, it used a paste electrolyte instead of a liquid. This was the first battery suitable for portable electrical devices, as it did not spill or break easily and worked in any orientation

How to Select a Flashlight?

1: Decide on what lighting technology you need. You can basically choose from LEDs,High-output LEDs(CREE, LUXEON, or other Watt LEDs), Xenon or Incandescent lights.

2: Find out what type of power source is more convenient to use. Most flashlights use standard batteries such as AAA, AA, D and C. However, it would be best to save much on purchasing batteries and helping the preservation of nature by just purchasing one that uses rechargeable batteries. There are also solar powered ones but you will still need to recharge it using solar energy. This could be a great choice in case you are on the road and you do not have a charging station available.

3: The size of the flashlight also matters. For those who are always on the go or for those how have limited space, consider choosing the more compact ones. They are easier to carry around and you can easily remove them from your bag. However, make sure the size does not compromise the efficiency of the flashlight.

4. It is better to choose the Famous China brands, such as Ultrafire, Fenix, Small Sun, Romisen LED flashlight.
