I have been searching for a decent book light that clips onto a naked Nook Touch, but no results have yielded that seems to scream "securely". I'd like one that:
a) makes use of the depressed bevel at the back,
b) shines brightly without flickering and over a decent area,
c) is not too heavy (max 1 AAA battery size),
c) and is relatively resistant to abuse.

I quite like the design of the Kandle but it doesn't seem like it would clip on securely and the lighting for bottom part of screen seems to be an issue.

I also quite like Mighty Bright Travelflex but no pictures or comments told of how secure the clip is.

I'm quite confused about the Lyca light under B&N because of all the information. Is it secure or not? Is it bright or not? Is it too heavy?

Right now I'm using a $1 book light which I expect to last 2 weeks, so would welcome all suggestions!
