It mainly adopted the most advanced solar-energy battery from overseas which can self-charge,it can work without any electricity.This light was self-control,when the ray can satisfy the technique,it can work and make sure the function of caution.The appearance is a super-thin profile,individual hexagon shape design,clear line and full-sealed design. It mainly adopted LED as the lamp-house,had no machine part.No mechanic abrasion or noise.High light efficency ¡¢energy saving¡¢good light¡¢strong anti-backlight and penetrating-fog ability¡¢steady performance and long power consumption. Double layer of aluminum alloy provides strong anti-impact ability and can bear corrupt.PC dome,electroplated with crystal ,it was dealed with by the advanced technics,so the dome have much higner transparency,better anti-aging and hard to color fade.
