Yeah, drgentr asked for 4500K so I tried to get close to it, I agree it’s not worth it.
For lower CCTs, here are the tints I get in a tint ramping flashlight for example :
Using 6500K-2000K would have lowered the duv even more, as shown in maukka’s test, and for a larger portion of the CCT range. (also in this flashlight the leds run at half current at the middle of the tint ramp, so the duv is not as low as it could be )
