Just ran across this.. Interesting idea. Also customizable.
I don't see any method of current control besides the 20v power supply limit.

De-solder the ends and add 7ldd-hws and it's a $200 constant current dimmable panel in the color of your choosing..
Not sure 20V's is enough but (3x6 = 18 reds help drop the V(f)
Adding a different ps would help but adds to TCO.

More for curiosity than functional.

That’s way above my head, but thanks for the details

It would be tempting if it used at least cree diodes, but I think it would be more cost effective to just buy a black box and I think you'd get more for your money too. But I guess that's why no one really does DIY LEDs anymore.
