LED Flashlight With Waterproof Function

LED flashlight is a new type of flashlight with LED (light emitting diode) as light source. Common LED flashlight has a small key ring type, multi-lamp type, single lamp high power type. Good LED flashlight with waterproof function, good seismic performance, that is resistant to fall. Because LED has high brightness, low power consumption, long life, small size and other characteristics, it is ideal for portable lighting.

Buy skills

How to buy high power LED flashlight (for reference only):

One, look at the bulb

1, the number of head, 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 waste, for other special needs can be determined according to their needs. Of course, high-power Hight Power LED flashlight generally can not reach the number of 12.

2, see the brightness, good LED flashlight high brightness, slow decay.

3, look at the bulb, in the case of extinguished, the naked eye is difficult to distinguish it from good or bad, you can see the light bulb in the case of consistency.

4, look at the aperture, good LED flashlight aperture for a uniform circle, poor LED flashlight spot is divided into yellow and blue uneven distribution. Earthen condenser surface as much as possible to concentrate. This flashlight is not like ordinary flashlight can adjust the focal length, purchase should be careful not to astigmatism.

Second, the internal structure

1, see welding, welding to prison. Each diode is connected through the welding on the circuit board, if there is poor contact with the Weld, it may cause the ball does not shine or affect the overall use.

2, see the battery, there are two kinds of ordinary batteries and lithium, 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.

Third, the external structure

1, to see waterproof, good LED flashlight with waterproof function, good seismic performance, that is resistant to fall. Because it belongs to the electronic products, flashlight in front of a circuit board, once the water prone to short circuit, causing damage.

2, look at the appearance, you can choose aluminum alloy shell, beautiful and generous.

3, look at the shape, according to the specific use of occasions and use, you can choose the appropriate size of the size of the flashlight.


1, led long service life, generally up to 5 to 10 million hours or more, than the traditional tungsten lamp life is 5 to 10 times higher.

2, cold light, low heat, will not damage the lamp holder, high security.

3, the reaction speed, impact resistance, good weather resistance, small size, easy small and lightweight.

4, energy saving, energy saving, low power consumption, green materials.

5, the reaction speed as long as 1us (microseconds), no warm light can improve safety.

6, low-voltage drive (voltage of 1.8 ~ 4.0V) security.
