Overheat protection for Fenix HM51R Ruby V2.0 headlamp
The operation of the Fenix HM51R Ruby V2.0 headlamp on the highest mode is limited to 1 minute, then the power is gradually reduced to about 500 lumens within 5 minutes. If the internal temperature of the lamp rises above 60°C, it will automatically begin to further reduce power in gradual steps until the temperature stabilizes. Once the temperature of the lamp drops below 60°C, the power will gradually increase again. Operation in 400 lumens mode is limited to 5 minutes, after which the output is gradually reduced to 200 lumens over 5 minutes.
Battery charge indication
After a short press of the button (the headlamp must be switched off), the LED indicator in the button is activated. If the indicator light is green, the battery is more than 80% charged. Green flashing indicates 50-80% capacity. If it is red, it is charged to 20-50%. A red flash indicates that less than 20% of the battery capacity remains. The indication only works correctly with RCR123A / 16340 rechargeable batteries.
Charging the Fenix HM51R Ruby V2.0 headlamp
Unclip the rubber cap of the charging connector and plug the included cable into the flashlight (USB-C connector), plug the other end of the cable into a computer, power bank or USB mains or car adapter (not included).

If the battery voltage drops below the set level, the headlamp automatically switches to lower power modes. If the headlamp is already switched to the lowest power mode and the battery is critically low, the indicator in the button will flash red. However, the Fenix HM51R Ruby V2.0 headlamp will continue to glow until the battery is completely depleted.
