Thanks to all for your responses. You've undoubtedly saved me time and aggravation. I believe it was Poor Richard's Almanac which said "Experience teaches a dear school and a fool will learn in no other." I'm glad to be able to absorb experience without having to "get burned." The ARC-AAA is on my Christmas wish list; however, for the purpose of backpacking, I'm going to stick to my AA Mini-Mag with Nexstar bulb & lithium AA batteries. It's the best compromise between spot, flood, weight, durability, and brightness I can currently find. I'll probably get a Photon for tent/tasklight/backup. The ARC-AAA is a terrific light but not well suited for backpacking when you sometimes need to "reach out and touch someone" with the beam. It's a shame a focused incandescent and diffused LED option aren't avail in 1 small/light package. I'm still searching for that perfect combination...small/light/bright/long runtime. A man's reach should exceed his grasp. Again, thanks
