Wouldn't a book light have a lot of wasted light, falling on the bezel, falling off the sides of the e-reader, or bounced into ambient light around the room? That would be unappealing for me given I have to not disturb my partner in bed.
In your case I'm sure a self-lit Kobo, Kindle, or Nook would be a better option if you get a good one. But light distribution is not more even on them as compared to a well positioned clip on.
