A word of caution,
When you are hunting brown furry things that drip blood, finding things in the dark with LED's can be difficult when you loose brown contrast and red colors are under represented in your light spectrum.
Headlamps are also very nice, especially if you have to field dress something and do not have a third arm handy for holding a light. There are several model headlamps that combine a standard incandescent light and low output LED's with long runtimes. Many of these can run on standard AA's. Plus it is much harder to drop when hiking over rough terrain while you carry all you other gear as well.
