Intelligent Memory Circuit
The flashlight memorizes the last brightness level used in the General mode, the next time it is turned on, it will recall that previously used brightness level.
The flashlight will accumulate a lot of heat when it is working at Turbo and High brightness level. When it works at Turbo for 5 minutes, the flashlight will automatically downshift to High output to prevent the light from overheating. If the Turbo output is needed, please reset it again. But the flashlight could be damaged or the normal service life could be shortened because of continuous use like this.
