If you want to upgrade your house entrance with a power-efficient and bright light, then you should go with something like the dodocool Ultra Bright Solar Powered Light. Why? Because apart from being powered by the sun, it automatically turns on when motion is detected and turns off or stays lit slightly when no motion is detected for about 10 seconds. Being solar-powered, it requires no wiring.
To power the light, an integrated monocrystalline silicon solar panel is adopted with a maximum solar conversion efficiency of 17% as part of the light. All you have to do is install the lamp at an appropriate sunlit position and the built-in rechargeable 2600mAh Li-ion battery can store the power for up to 500 times illumination after one-day charging. That’s it! No electricity used at all.
The motion detector offers sensing distance of up to 32ft with a 120-degree sensing angle and it stays off during the day as it has an ambient light sensor. Once the ambient light drops below a certain level, it automatically turns on when motion is detected and turn off 10sec or more after the motion stops.
