Intelligent Downshift

Time-limited Downshift
The light will downshift to 900 lumens within 30 seconds when it has been used on Turbo for 1 minute.

Overheat Protection
The light will accumulate a lot of heat when used on Turbo or High output level for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down by 5% every 10 seconds to reduce the temperature, and until to 350 lumens. When the temperature is reduced below 60°C, the light will automatically step up by 5% every 10 seconds, and it will then allow the user for the reselection of Turbo mode.

Low-voltage Warning
When the voltage level drops below the preset level of 3V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output mode, the battery level indicator blinks red to remind you to recharge the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery level runs out or the protection board activates.

Note: This only works with Fenix ARB-L18 18650 Li-ion battery.
