I was planing on running 2 off of that driver. Sure if you want to see what drivers. will work that would be fine. I would like to have some voltage headroom.
HLG-480H-C1750 I think this may work https://www.meanwell.com/webapp/product/search.aspx?prod=HLG-480H-C
Do you think that is enough heatsink for these cobs... from rapid led.
These holders...

Each of those drivers will run 4 cobs at 1750 wired in series.
Holders are holders. If they fit they’re fine. If you’re getting pre drilled heatsinks then contacting the company would be better but they’ll probably sell you their shit which is fine just a little more pricey. Never got pre drilled.
Heatsinks should be rated for a wattage which would give a general idea. I couldn’t see it on the site. Maybe write them an email.
Wouldn’t take this calculation very seriously and always go with bigger dimensions than the minimum required ones but this helped me to decide on the absolute minimum volume of heatsink i needed.

There was one calculator which included fin count and shape but couldn’t find it.
