Thought I would start this off with a little un named chinese model which my missus bought that came in a pack for plucking eyebrows. It was attached to a large pair of tweezers but she couldn't use it as the light from the torch nearly blinded her when she tried it! (don't laugh) I now have it and it makes a perfect lightweight camping torch. Its 1 1/4" long, 3/8" diameter weighs 1/4 ounce and 3 LR41 button cell batteries power its single led-i'm guessing but it looks around 8/10 lumens-fairly bright and useful light on a dark night in the woods. Has anyone any smaller than this(lol) have fun Tom.
