My bad. BTW, if anyone out there still has their old modules, do an emitter swap with a newer emitter, like an XP-G R5. We measured 160 OTF lumens on the one that I did and that one has an R4 in it along with a UCL. The best part is that the older module draws slightly more than half the amps that the newer module does and can make more light doing so with a modern emitter.
