How to lengthen flashlight’s service life:
1. Flashlight’s LED and body will be poor contacted because of circuit’s oxidation
and friction during daily use. We suggest clean thoroughly the contactor and
lubricate the thread once a month.
2. The head of the light is not anodized processed, in order to reduce the circuit’s
loss, we don’t suggest to open light’s head unless you have to do cleaning and
maintaining.
