This thing is pretty bright -- almost in a bad way. I have a history of sleeping for a few hours and then waking (and staying awake) in the middle of the night. I wanted to read on my non-backlit Kindle so as to try to calm my mind, but this light is so bright that it wakes my husband up...which defeats the purpose. On the other hand, it certainly provides enough light to read so that my eyes aren't strained!
