1A is not the tint most of us would get for a C8. Cooler color temperatures have more visible backscatter, making it hard to see what you’re illuminating far away.

Low-CRI SST-20s typically out-throw XP-L HIs in regulated flashlights. High-CRI SST-20s are about equal, but the improved color rendering helps you see objects that don’t stand out against their background. I own a C8 with a 95 CRI SST-20 (4000K), and I think it’s worth giving up a bit of output.
