Super-bright efficiency led chips Unique Wide Angle Design offers a larger coverage of luminosity. The corner LEDs put out enough extra light to really make the solar light very efficient as a whole. High-efficient Solar Panel this light works automatically without electricity as the solar panel absorbs the sun rays and generates power for the light. Our solar panel of monocrystalline silicon converts up to 20.5% of the sunlight into electricity energy which ensure long lasting standby time.
