Ray ... I am using it without the optics, it looks better this way, is watertight with th eo-ring in place and lights up a room pretty well on high and low mode ... just what I need at home.
Klaus ... would love to show a pic like that, but unfortunately I neither have a Katokichi CR2 nor a LL CR2 ... /ubbthreads/images/graemlins/smile.gif .... sorry.

EDIT: with the CR2 body it is a few milimeters shorter than an ArcLS2 and with the CR123 body a few MM longer while being a tad bit slimmer with both bodies. The bezel is tha same diameter.
