I love this. The light sits an a magnet scooped shaped base. It is made to fit on it so you can move it to any angle, heighth or direction. It is really cool. You can set it in baby's room or kids room. It has a sensory for motion to turn it on. I use it at the beginning of hallway so it turns on when I enter it so I can see my way to the bathroom. You can charge it by USB but also can use batteries. The funny thing about this, is that when I opened the box the light went on. So I don't know how long a charge lasts, but I am sure it took days to ship. So the charge must last a long time.
