I'm upgrading the greenish XM-L T6 in my TK41 but don't know much about tints. I recently did a micro mag build with Fasttech's XM-L2 U2 4c but find it a bit warm for my taste. A nice neutral tint XM-L2 would be great in at least a T6 brightness bin. So please do let me know what you like in a 3 amp thrower. Beamshots are great as always. I'm all ears.
Another vote for 3C here. I have two lights with the 4C and one with the 3C. I find the 4C to be a little too creamy, and almost yellow at lower brightness levels. To me, the 3C is a beautiful neutral white.
I don’t have a good enough camera to do beamshots. Wish I could post one for you.
