I have two Single Mode Nichias. One is warmer than the other (219A vs 219B?) but both have the awesome CRI, though I tend to reach for the warmer tinted one. Also have one of the two Two-Mode tripple Nichia (also warmer than my original triple).
I don't know if it matters the time when I got them, but the one that is cooler was from when they first came out, then the warmer ones (single mode and two mode) I got months later.
I have replaced my Solar Force lights with AR coated lenses from KD and Int'l Outdoor. KD lenses have purple AR and IO have blue AR coating. Only for the IO lenses, does the color in the coating come through on the beam, but only on a white wall and only on the very edges, but not noticeable in real use.
