After reading many reviews for many different book lights, I decided on the Mighty Bright. It has turned out to be a fantastic decision. This little clip-on gives off the perfect amount of light for my Kindle. I just clip it to the top, and I can read in bed without disturbing my husband! It's also handy for low light conditions. I like to keep my living room moderately light in the evenings, and while it's sufficient enough to read in, the Mighty Bright makes it MUCH easier! Whether using this for a book, or your Kindle, I absolutely recommend it, the soft foam on the inside of the clip ensures that it will stay in place no matter where you put it, and it won't scratch your Kindle!
