Well, I don't have a LxT, but I've got a P1, and I imagine they're grabbing the Luxeon IIIs from the same pile. Mine has a very cool white tint. Not quite blue (unless I shine a WO next to it). If I had to guess, I'd guess it's a YA tint, if only because it's still cooler than my TYOJ McLux PD, but it could just as easily be YO tint. It doesn't have any purple to my eyes. I have a vague notion that if I had any green tinted LEDs it might look purple in comparison.
Anyway, it's a cool blue.
