What I would really love is a small flashlight, say about 5-6 inches long with a straight barrel, something the shape and length of maybe the fenix l2d or the inova x5, but twice as thick so it can take four batteries instead of 2 and have a really long battery life. So: 5-6 inches long, uses 4 aa's or aaa's, and hopefully puts out approx 75 lumens. Does this exist? I don't think it does, but here's hoping.
