If you can convince luminarium iaculator that the emitters are the ‘old style’ he might buy the quad light just for the LEDs! Check his thread here for how to tell if you have the old style XP-G2 or the new, which has less throw and a not-so-nice tint when de-domed. Of course, if they are a couple years old, they are sure to be the old style, because they just changed recently. Send him a PM and you might make a sale today!
