PRODUCT INSTRUCTION The product adopts new type rear mounted generating illumination equipment, which reserves the traditional round-shape outline of flashlight, and adds the shake self-generating and energy storage system. It adopts multi-layer acceleration gear group, with light sense and high efficiency. When shaking it for 120 cycles, (Use one lamp, illuminate for one hour, use three lamps, illuminate for 20 minutes, use six lamps, illuminate for about 8 minutes.) The more the shaking loops are, the faster the speed is, and the longer the illumination time is. When the power is not enough, just shake again. (The effect for shaking charge will be better if shutting the power supply.) The user can control the lamp quantity for illumination (LED Light Emitting Diode) through the switch according to the actual illumination environment. Press the switch once, illuminate one lamp, press the switch twice, illuminate three lamps, press the switch thrice, illuminate six lamps and press the switch for the fourth time, the power is cut off. Due to highly practical application effect of the new product, it can basically replace the flashlight with ordinary battery illumination.
