My nephew got me one of these Coleman Cree pack-away lanterns last Christmas. I think he bought it at Wally World.

I avoid D batteries, so I immediately did a conversion using rechargeable lithium ions and a couple of alligator clips. This is dirt simple; anyone can do it, even in the field. The light runs fine on the 3.6 VDC from the lithiums, and will light up with voltages down below 3.0 volts. So it's pretty versatile.
(The other LED "lantern" I use a lot is a 2AA or 3AA mini-maglite in candle mode. Why? Because it's always at hand.)
