Mark update this lamp from XP-G or G2(?) 2016 to XP-L. Now they are offering Nichia 319B, Nichia 319A, or Cree XP-L LED emitters. Temp and output was also listed on they web site. To me it looks like Cree XP-L.
Out of curiosity, I took a few photos of LF M3T to see it they might help determine what LED is sitting there.
From left to right we have:
1. SureFire KE1C, 200 lumen TIR equipped head. My warmest SF of unknown color temp.
2. LF M3T that is the big mystery, at 9V here.
3. Malkoff M61N SST20 4000K, 400 lumen drop-in. The only one with known color temp.
Contenders:
And three photos, at fixed exposure and three different WB temps: 4000K, 5000K and 6000K:
In real life M3T drop-in is definitely not green to my eyes. I can't determine which one is it though. If someone would have a better idea, please share :)
