I want to get one of the new HDS Ra's to mod to an XP-E, i was originally going to get the 120T, thinking why spend the extra money for the 170 only to switch out the emitter, then a thought dawned on me, how does Henry get the extra 50 lumens from the more expensive model, they both use Osram Golden Dragons,does the 170 have a higher output driver, or does it simply use a more efficient Golden Dragon than the 120 version?
