If anyone cares, I have ordered one of these. It might take a month to arrive from China. I'll post a report if and when.

It occurs to me that I have another plastic 1AA headlamp around here, made by Icon, Paul Kim's old company. (Paul Kim was Surefire's chief flashlight designer, and I think the Icon company is gone now). I don't remember what the model was called but I do remember liking the light. If I can find it I can weigh it, I guess. I had two. I used one for a while and now don't know where it is, and the other is unopened but I think I can find it. I have no real reason to keep saving the unopened one, so I may as well open it.
