Yeah of course... but look for the good driver first and then at the emitter efficiency... wanting a XM-L for the different beam profile over an XP-G makes more sense imho. But seeing/owning 8-10 1AAA lights primarily for use on NiMHs... I can tell you that emitters aren't the end all aspect to consider. I would choose the DGQ tiny II with a TIR (XP-G R4 NW) or my Brinyte PD03A ("obsolete" XR-E with a short reflector) any day over my Maratac/ITP/Blackcat/Tank 703 when it comes to " general beam usefulness". Unluckily I don't have a store around the corner, where I can try the lights first. I think people concentrate too much on single aspects these days rather than looking at light engines as a system consisting of driver/emitter/optics. The problem is that recommendations are so subjective, so we tend to cling to hard evidence in form of tech-data and reviews, because these can be verified.... but more than once I was totally mislead and my expectations were not met. After buying 50+ lights and keeping about 30 of them... I still fail to translate the reviews/tech-data I read into a ruff idea what to expect in that little envelope in the mail.
