Thanks for all the rec's so far. I think I like the idea of having a flexible arm so I can position the light. It seems all the lights are LED so probably the brightness may be similar. The idea of just a regular AAA battery is also appealing instead of using the little disc cells which are a pain to get sometimes, not to mention more expensive.
I'm trying to avoid getting a cover for my reader (I've got a vinyl skin on it) hey, why add bulk if I'm only reading at home? So maybe there's one that clips to the reader without scratching it. I think Amazon's got all the lights mentioned above. Thanks for the input everyone
maybe I'll find something close to perfect *crosses fingers*
