Why does the GL07 step down a few lumens after being used for a while?Updated 6 hours ago
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 55°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 brightness level decreases correspondingly. When the voltage level drops below 3 V, the light blinks 3 times every 2 minutes to remind users to recharge or replace the battery in a timely manner.
*This feature only works with a Fenix ARB-L16-800UP rechargeable battery.
