Q7. Why does the GL30R step down a few lumens after being used for a while?
A: There are two reasons:
1. Intelligent Overheat Protection
The light will accumulate a lot of heat when used 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.
2. Low-voltage Downshift
When the voltage level drops below the preset level, the light will gradually decrease output level accordingly. When the voltage level is still too low, the battery level indicator will blink rapidly to remind users to recharge or replace the battery in a timely manner.
*This only works with a Fenix ARB-L18 rechargeable series battery.
