Interesting 3 year old thread ressurrection. I think a 1AAA headlamp would be unusefully small with problems of output vs runtime making for very short runtimes at high output, or long runtimes at low output. Perhaps when LEDs are available in the 200lumens per watt range it could be revisited again.
I think it would be of limited use but the main issue is I don't think anyone would pay $60 for a Zebralight AAA. The only point would be small and light weight but if made from metal you might as well just make it a AA headlamp.
If it was cheap and a niche type of headlamp I can see a very lightweight (1 AAA lithium) headlamp that only has a high of 50 and a low of 5 lumens with a very floody beam. Put in in a comfortable headband where you don't even feel the light. It's a walking the dog at night kind of product
