True on all accounts. I wouldn’t even notice the lumen difference by eye between XP-G3 & XP-L. I guess another important issue would be the beam pattern created by XP-G3 vs. XP-L.
If it helps, teardown pics of the BT40S are here and beamshots stock here modded vs. stock here.
(Sorry, at this point I should have started a new thread!)
Thanks,
