Intelligent Overheat Protection 

The light will accumulate a lot of heat when used on Turbo output level for extended periods. When high temperature(≥ 65℃ ) is detected or after 3-minute working on Turbo, the light will automatically step down by a few lumens to reduce temperature. 

Low-voltage Warning 

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the flashlight blinks three times every five minutes to remind you to replace the batteries. To ensure normal use, the flashlight will not turn off automatically and will work until the batteries protection activate. 

Battery Replacement 

Unscrew the tail cap to insert the battery with the polarity markings in the correct direction according to the signs on the bottom with the anode side (+) towards the light head, then screw the tail cap back on.
