If it is not going to be a "pocket carry" or keychain light, then 2 AA batteries is superior to only 1 because of the longer run time. I have a LOT of small flashlights, and some of the Maglite drop-in LED modules as well. The absolute best product balancing price, size, output, throw distance, light color, and quality has to be the new Fenix L2P. Slightly smaller than a 2AA Minimag but a thousand percent better overall. Fantastic throw, durable, uses 2AA batteries. Will run around $48 + shipping. But - you can't buy a better light for the money.
