That's a nice find there, and I'm glad there's finally a US supplier. I wish more premades came with the CXB3070's though, since they are cheaper. I was able to assemble those for about $60 each (with a separate driver for each,) probably more like $75-$80 if I had to buy heatsinks. They even carry reflectors too, though only 120 degrees.
Edit: The more I look at these, the better they look. The kits even have a built-in dimmer and don't require fans!

Yes, it is a pretty nice kit, and a pretty good deal for people who doesn't want to assemble. The MeanWell HLG drivers have one of the highest DC/AC conversion efficiency, and the 3-in-1 dimmer is handy.
I did look into the Cooliance heatsink. It is supposed to be 100mm x 70mm Cooliance CPL10070 according to post #30 in this thread.
Thermal resistance is 1.03C/W. So the LED will become ambient + about 25C. So it is within the operating limit of LED and it probably works. Passive aspect (no fan needed) is nice, but I would prefer a bit more cooling for better efficiency.
I'm sure you could just add fans to those heatsinks yourself, as long as devising a mounting system isn't too difficult.
