Intelligent Overheat Protection
The lamp will accumulate a lot of heat when used at Turbo mode for extended periods. When the lamp reaches a temperature of 60°C or above, the lamp will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of Turbo mode.
