• Red light flashes: critical 25% - 1%

Note: This only works with Fenix ARB-L21 Series 21700 rechargeable Li-ion battery. 

Intelligent Overheat Protection 

The light will accumulate a lot of heat when used on Turbo and High output levels for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode. 

Low-voltage Warning 

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the battery level indicator blinks red to remind you to timely recharge or replace the battery. Note: This only works with Fenix ARB-L21 Series 21700 rechargeable Li-ion battery.
