This is an awesome solar motion sensor light for outside! It is nice and bright. It has 38 LED lights. It is powered by two LG rechargeable solar lighting batteries. It can sense motion anywhere from 15-30 feet of the sensor. I really like that even when it is cloudy outside it still can charge. The charge time is 6 hours. It is durable and well made. It is easy to install. It has three modes of lighting: soft light motion, motion detection only, and continuous light. You can change the mode of lighting you want by simply pressing the button that is above the actual light. When the light is activated it will come on for about 10 seconds and then go off.
