I like the Zebralight H52FW. It will take a rechargeable Li AA or a regular alkaline AA. I like to go out with the Li and take a spare alkaline AA in my pack. The battery life is great in either case. The beam has a very uniform cast (no light/dark halo effect), and it has a wide range of intensity settings and can be dialed down to almost nothing for reading in your tent or hammock. BTW, the "F" designation stands for "floody" beam (vs. no designation for "spot"). Similarly, the "W" stands for neutral light, which is more natural and picks up more color than their cool light, which has a bluish florescent appearance. The latter gives better light/dark recognition, but colors are nearly lost. It's also very reasonably priced, IMO, against comparable models. I use it for hunting, hiking, XC skiing, etc.
