Reasons of the inferior LED flashlight will be damaged easily.As the unstable driver circuit of the poor quality LED flashlight(some non-circuit)and the blind pursuit of increased brightness, it will cause damage or aging LED. The details is as following:

1.Voltage instability. Quality imported IC circuit drives intelligent control, so that the output current and voltage stable;
2.LED light quality problems, poor quality LED flashlight using a B or C grade LED lights to reduce costs, the LED willappear with aging and darken soon ;
3:Heat dissipation, excellent quality aluminum LED flashlight use, heat is guaranteed;
4:Waterproof problems, poor flashlight with bad waterproof, water entered easy, causing damage to the circuit;
5:Production losses, the cottage factory can not provide a good working environment, result to static damage LED chip or caused  hidden damage
