This is not meant to be a book light
This app works fantastically as a night light. Other reviewers are complaining that its not bright enough. I however find the settings perfect. It puts me at ease as i doze off. There are also several different lamp options you can choose from which is pretty snazzy. I love this app! If you are looking for a book light perhaps you should try the flash light app instead.
