It has a touch on and off sensor, I love that about these lights! And it also comes with a remote. So I plan on placing these in a room that I’m using as a library, and these will focus on the chair that i'm going to be reading in. I'm going to place them on the wall above it. The lights can go from very bright to very dim, And I believe they also have a wide color range, which I absolutely love. I like reading with red lights or reading a scary novel with blue or orange lights. I think that's pretty cool. Also, the installation is quick and painless. You can charge these lights instead of having them plugged into a wall or trying to hardwire them into your electrical system. I am not for that! Ten out of ten I definitely recommend!
