Operation Instruction

Rotate the magnetic ring to turn on/off the light, to select the wanted output level. From left to right: off, Low, Medium, High

Safe Diving Illumination Design

If the detected voltage is too low for the High Mode, the output will automatically step down to prolong the runtime.
Advanced Temperature Regulation (ATR) technology
The light will accumulate a lot of heat when used at High Mode for extended periods. If the light reaches a temperature of 55℃(131 °F) or above, it will automatically step down by a few lumens until it won’t get hotter.
Meanwhile, after used at High Mode for 3 minutes, the light steps down slowly until Medium Mode is reached.
