Intelligent Overheat Protection
The lamp will accumulate a lot of heat when used at Turbo output level for extended periods.
When the lamp reaches a temperature of 55°C or above, the lamp will automatically step down a
few lumens to reduce the temperature. When the temperature drops below 55°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 headlamp is programmed to downshift
to a lower brightness level until Low output is reached. When this happens in Low output mode,
the lamp blinks 3 times every 5 minutes to remind you to timely recharge or replace the battery.
