Intelligent Overheat Protection
Advanced intelligent temperature regulation technology allows MK38 to dynamically adjust output performance according to its body temperature.The light will accumulate a lot of heat when you use it at high-output levels for extended periods. When the light reaches the temperature of 65°C or above, the light will automatically step down its output to reduce the temperature. at the same time we also make more premium cooling fins on flashlight head and built-in duable-row fans to blow effectively these cooling fins through the outside to protect flashlight overheat.
Note: DO NOT submerge the flashlight into any liquid when it is hot. Doing so may cause irrepareable damage to the light due to the difference of air pressure inside and outside of tube.
