Intelligent Protection

The light will accumulate a lot of heat when it is working at Turbo mode. When the light is overheated up to 65 ℃ or above, the flashlight will automatically step down a few lumens to reduce the temperature; when the temperature is lower than 65 ℃, the output will gradually return to Turbo output level.

Low-voltage Warning
