It's a typical white LED, probably on the bluish end of the spectrum, but I don't know the color temperature. My problem is more staying awake to read the next chapter than being able to fall asleep, and that doesn't matter whether I'm reading on the kindle, a tablet, or a paper book. I tend to fall asleep (and wake up) around the same time every night regardless of whether I read beforehand or not.
