Hmmm, I sort of "dabble" at being a flashlight junkie. I have a couple of Vizeri and use 18650s in them. They can throw a beam at least a half mile on "high" and are dazzling if you get hit in the eyes with the beam. They're small enough to be "mouth held" in a pinch, but I've been considering a headlamp style. Problem is one of the guys I used to work with had one, way back before CREE bulbs, and looked kind of like a weakly illuminated dweeb when he used it.
Is the battery weight noticeable with a dual battery headlight?
