Will be camping for about 2 weeks in region H. Will be using light for 2 - 3 hours or more in morning getting back in and the same coming out.I think I would like to use AA batteries,those C123 batteries are to exspensive.Charging isn't going to be an option.Anyone have a good reference to the many choices? I think the LED is the way to go,but wow there is alot of choices. Thank you Dick56
