Flashlight, it is a portable hand-held lighting tool, which is developed through electronic microcontroller integrated circuits. It can be applied to many scenes: furniture, night patrols, outings and other scenes! With the pace of science and technology, the luminescence of the flashlight has also been developed into an LED lamp bead aperture, and the brightness has also qualitatively exceeded.
