This book light is great.  I like the fun purple color.  The light itself has two settings of brightness.  I do wish it had a dimmer setting, but it is not a huge problem.  It clips right onto my kindle and lights up the whole screen.  Now I am able to read in bed and not have to worry as much about disturbing my partner.  This reading light will also come in handy for travel.  The price was also excellent.  Great buy.
