I read paper back books and this is a great light!  I love the two selections of brightness and you can adjust it in many ways. It is kinda bulky and I noticed with this blue one it left a little mark of the blue color on my book page. Nothing that significant but slight smudges. I would suggest using something like piece of paper towel to put under the part that clips to the page of book so the color doesn't smudge off on it. Other then that it's definitely a a great light to read or even other things to use for. I use it for night reading in my bed
