CR 123 batteries don't last long and are not rechargeable. AA are good and you can get rechargeable but it takes several batteries to give you enough power. I have a Fenix TK-45 led light with 760 lumens but it takes 8 AA. Still its only the size of a 2D maglite.
I usually carry my single cell Solarforce L2P with a 650 lumen led and one 18650 rechargeable lithium battery.
People always seem to want a light that has a lot of throw. I find that pretty usless. A flood beam is much more practical. My TK-45 and L2P both light up an area really well.
