Intelligent Brightness Downshifting Sensor The flashlight has a built‐in intelligent sensing circuit. When the light surface is close to the lighting object (about 60mm) for more than 1.5 seconds, the flashlight will automatically downshift the output level to Eco to avoid danger caused by high temperature. When the light surface is more than 0.8 seconds away from the lighting object, the flashlight automatically recalls the previouslyused output level. *As objects of different materials and colors reflect differently to light, there will be slight deviations in the sensing distance. Intelligent Protection Time‐limited downshift With the light switched on, if Turbo is being selected for over 20 seconds, the light will downshift ...
