Review on DLLT Dimmable Clip on Reading Light: 48 LED USB Bed Night Lights with 3 Colors, 15 Brightness Level Book Light. Flexible Clamp for Makeup Mirror, Desk, Bedside, Headboard. Ideal for Piano, Computer Light. (Silver) by Janet Hernandez

I bought this for my 14 year old girl who likes to draw on her desk and sometimes needs some extra light. She uses it in the evenings when she lies on the bed to tidy up the room a bit. She uses it quite often, sometimes just for convenience and sometimes for functionality. I would recommend it has three settings and they are all great, I'm very impressed. It appears to use very little power, has an LED backlight, and puts out just the right amount of power. I think the only thing I would change is a longer cord on the wall.
