I have a hard time with the clip on ones. I was thinking of getting this:

http://www.amazon.com/Periscope-Paperback-Booklight-Cover-Black/dp/B001O02HSS/ref=sr_1_92?s=electronics&ie=UTF8&qid=1350415439&sr=1-92&keywords=book+light

I have a kindle but some books I like to read are only available in paperback. Can anyone recommend a good reading light? Are the clip-on lights the best or is there something else? Thanks!
