The beam is very clean, with nicely focused hotspot and smooth transition in the spill.
Very happy with the not excessively pink LED, as requested. Also pleased with the higher than expected output. (Lumens from my own meter.)
mcbob measured the LED at duv -0.0065.
My Opple reads -0.0040 on H1, and -0.0014 on M1.
