Awesome! Thanks for doing this, and my compliments on the fancy white integrating toilet. It’s probably a good thing you didn’t try this one inside a styrofoam sphere.
98.4 is in the ballpark I expected, and the R9 is just about perfect. It is possible that the porcelain is not entirely neutral and is affecting the measurement of the reflected light, but I doubt it has a very large effect.
Nichia uses minimum. Some makers use average. Some users apply Nichia-style 4-digit specs to LEDs from other makers.
So it’s usually good to state whether it’s XXXX min. or XXXX typ.
“Got” the KR1 with W1 and W2 today. Can pick it up in the post office tomorrow. Will try to make a few beamshots for comparison, but there’s a small issue with the sun. The nights are not as dark as during winter.
