LED flashlight is a new type of flashlight with LED (light emitting diode) as light source. Because LED has high brightness, low power consumption, long life, small size and other characteristics, it is ideal for portable lighting.
Advantages of LED flashlight:
1, LED long life, generally up to 50,000 hours more than the traditional tungsten lamp life is 5 to 10 times higher.
2, cold light, low heat, LED Flashlight will not damage the lampholder high security.
3, the reaction speed, impact resistance, small size, LED Flashlight easy to light and other lightweight.
4, energy saving, energy saving, new environmentally friendly light bulbs.
5, the reaction speed as long as 1us (microseconds), no warm light can improve safety.
6, low-voltage drive safety.
Buy LED flashlight 8 note
1, the first few, the number should be moderate. The general use of the household should not be more than 12, the use of the battery in the 2 to 3 as well, and then a little bit of waves, LED Flashlight for other special needs can be determined according to their needs. Of course, high-power LED flashlight generally can not reach the number of 12.
2, welding, welding to prison. Each diode is connected by welding on the circuit board, if there is poor contact with the Weld, it may cause the electric beads do not shine or affect the overall use.
3, the battery, there are two kinds of ordinary batteries and lithium, LED Flashlight although the lithium battery is rechargeable, but low life, about 2 years, LED life of about 10 years, according to the actual situation to choose

5, light bulbs, light bulbs out of the case, the naked eye is difficult to distinguish between its good or bad, you can see the light in the case of light consistency.
6, waterproof, good LED flashlight with waterproof function, good seismic performance, that is resistant to fall. Because it belongs to the electronic products, LED Flashlight flashlight in front of a circuit board, once the water prone to short circuit, causing damage.
7, aperture, good LED flashlight aperture for a uniform circle, poor LED flashlight spot is divided into yellow and blue uneven distribution. Earthen polished surface as much as possible. LED Flashlight This flashlight is not like ordinary flashlight can adjust the focal length, the purchase should be careful not to astigmatism.
8, the appearance, you can choose aluminum alloy shell, nice.
