Thanks for the ideas, but I am looking for lights that can take a AA or a CR123 cell like the three above. I am aware that they will also take rechargeable cells. I already have the Zebralight SC80 and the Jetbeam Raptor RRT-O XML, so far the SC80 is the only one I found that you don't
have to add a piece for it to use both batteries. The RRT-O and the V10R you have to carry around an additional part.
