when I ordered lately, there were tints 1A, 1B, 1C available.
they are all about neutral white, I liked the 1B best.
from the datasheet, http://www.cree.com/products/pdf/XLampXP_B&L.pdf
the 1A is neutral, the 1B a bit into blue/green, the 1C a bit into yellow...
but lets face it: even someone who deals with these tints a lot, does have a hard time to see the difference and needs direct comparison.
take care fo all those base options there at Cutter ...
I just ordered the XPG R5 1C tint as I like the slightly more yellow tint but until i have fired them up I will not know. Will post some beam shots when I get myself organised.
