Its not AA powered, but I'll put in a thumbs up for the Doug Ritter eQ multi light, http://www.aeromedix.com/product-exec/pa...eQ_Multi_Light. Runs on small CR2032 batteries that cost ten cents a piece when bought in small quantities. Nice, lightweight (1 oz), easy to change the batteries. The spot light on this headlamp is super, run time is good, great for hanging bear bags in the dark or focussing on work. I wear one while working on PCs and putting chains on my car in the dark. At $14.95, I own quite a few and have them in coat pockets, door pockets, anywhere I might need a light. This is really my only non-AA light or device, but for hiking its a good choice, as replacement batteries are extremely small and light. Really good value for this headlamp. Usual disclaimer, no relation to Doug Ritter or any vendor...
