Wish they had included actinic lighting. But from the experiment it seems one light is as good as the next. For the most part.
As for growth it doesn’t look like anything really grew much . Depending on the time the pics were taken.

After looking again I noticed the 20K MH is lower to the tank than the other two lights. Looks like you don’t get as much light out of a 20K bulb?
