Thanks! I think you’re referring to my beamshots of the D1, D1S, and D4 in TK’s D1 / D1S review thread.
My D1 and D1S are both XP-L HI V2 3A 5000K emitters.
My D4 is an early model with 219C 5000K ~80 CRI emitters, not the newer 219C 5000K 90+ CRI variant.
This info is in the beamshot photos but I’ll add it to my post as well.
