The Dorcy 1AA and 1AAA are pretty well built, but have lousy run times. If you're going to get a 1AA light, I'd pick the Gerber Infinity Ultra. It's half again as much as you want to spend, but it meets all the qualifications. It's durable, water resistant, decently bright and has a very long run time. You might be able to find a vendor that will give you a discount for a bulk order, or because it's for a mission trip.(or both)
