What Should You Consider When Choose A Flashlight


How to select a right flashlight is quite a personal selection. We should bare in mind that why you want this flashlight before you make the purchase. Will you use it for camping? Will you carry it in your car? Will you leave it at home in case of a power failure? Do you need something particularly large or small? Do you need it portable? Will you carry the light or do you want it to be able to strap on or mount to a stand?

There are several kinds of flashlight:wind-up flashlight, Xenon flashlight, LED flashlight and incandescent bulbs flashlight. “wind-up” and “shake” flashlights hey are very reliable due to their independence from batteries, but tend to be less bright than battery-powered lights. Xenon flashlight as a high power is ten or even more expensive than ordinary flashlight. It is suitable for outdoor activities such as camping, surveying, hunting, guarding, etc.The most used flashlight are LED flashlight and incandescent bulbs flashlight.Because LED flashlight have higher brightness, lower power consumption, longer life, smaller size and other characteristics, than incandescent flashlight, it is most used in our daily life.

For daily usage, A $10-$20 flashlight could meet all you need. But do forget that except wind-up and shake flashlight that require no batteries, other flashlights need batteries to power on. So select a right battery seems to of great importance if you want to use the flashlight. Alkaline batteries are your best choice for all around use. Lithium cells, which have a 10-year shelf life and perform better at low temperatures, may be the best choice for special uses. They may also be best for camping, and applications where cost is less an issue than reliability and output, as they tend to produce brighter light for longer. (On the other hand, unlike alkalines that taper off as they die, lithium cells tend to die more quickly when they finally decide to quit.)

Rechargeable NiMH cells may be useful for some purposes, if the lights are specifically designed to use them. They produce power at a high level for quite a long time, then die almost instantly. However, rechargeables lose their charge “on the shelf” after a few weeks, and should not be used for lights that are to be stored until needed.

Many LED lights operate on AAA and AA cells. These are easy to find, and spares don’t take much room. AAA and AA lithium batteries are available for special uses.
