XHP70.2 has a large tint outside the center. It goes in the yellow direction. I tried three different LEDs and each was terrible. MT-G2 is much more equal. The color is more uniform. As for TC20, I’m going to make one more modification. It will be 4x XP-L HI placed in the center. I think I like this version the most. When I do mod, I will describe the experience.
