I'm wondering _why_ all of AA powered LED lights, which I can google, are so thick? They are always like 19-21mm. But AA cell is _less_ than 15mm in diameter! Are they made to be bullet proof or something?
I'd appreciate it very much if someone could help me to find a skinny AA flashlight (no matter how advanced it is, just any UB LED light, which I can power with a single AA cell, in a 15-17mm diameter metal housing).
