Another comparison - brightness as controlled by the color. I'm just going to give the first digit since all six are the same. From left to right the colors are F(white) D B 9 7 5 3 1. All of them have the default settings, so 50% light power, and the light is centered in the globe.

I'll be testing some colors next, but having the desired brightness should make getting the correct color easier - pick the brightness then go right in the color picker to get the tint.

Here are the four dimmest (7 5 3 1) at 100% light power.
