The Nichia 219 is a neutral white 4500k 92CRI
The XP-G2 were mistakenly sent to Old-Lumens instead of Nichia 219 by illumination supply, and the switch was not discovered until after he had already modded several lights. I think it might be a 1D tint.

I don’t know what amperage they are driven at, but if you PM Old-Lumens he could probably tell you the amperage and what drivers he used.
