This Clip on Desk Lamp has 3 Levels Brightness !! With a simple soft touch, the light will change the brightness... The light is not a Stark Bright, but a Soft Light that has the 3 levels of brightness which for me is nicer for my eyes... !! It has a long bendable neck, that is charged by USB, and has a Long Battery Life. I am very happy with this clip on desk lamp !! I would definately recommend !!
