I bought myself the Xtraflex2 LED book light to use when I read in bed in the summertime. Even though I replaced our old screen with supposedly gnat-proof mesh, the tiny bugs were still flying right through when I used the regular bed light, so I use the clip-on, which is not bright enough to attract the bugs. Unfortunately, if I read for a long time, I begin to get a bit of eye-strain as this light is not quite bright enough for me. I've got cataracts starting in both eyes, so this might not be a problem for everyone.
