While browsing in REI today, I noticed a new version of the BD Cosmo (1 high power, 2 5mm design). The primary LED's been upgraded from an XR-E to a XP-E behind an optic, and now has a dimmer circuit instead of the old low/medium/high. There was also a new Gizmo (3 5mm) with the dimmer circuit and presumably updated LEDs. I assume the rest of their line is getting updated similarly. Didn't get a chance to play with out of the box, but the changes seem all for the good.
