If you ever needed light in places that you can not put a light fixture then this is the solution for you. You have 20 LED bright lights in one bar which has a magnetic sticky back that can mount on any surface. The light has a motion sensor so it turns on only when needed and turns off when not. This light does not waste any batteries it has a built-in rechargeable battery. A single charge will last about 5 to 6 hours of continuous use or about 30 days of needed use. Let there be light for any occasion!
