Alright
@SupraSPL For my clone lights I've ordered 4 each of the cree xp-l (v5-2a bin), 4 1 Watt 300mA drivers from fasttech you recommended, and the 4 35*35*10 mm aluminum heatsinks from fasttech as well. Since they have screws, can I mount them directly, or should I use thermal compound, or preferably could I use precut thermal adhesive tape like bond-ply from bergquist company? Here's a link to some thermal adhesive precuts that are 20mm, the size of the led stars.

I'm gonna wire each to separate drivers so I can move them around if needed, but the drivers will all share the same power cable source.
I'm about to order a cree cxa3070 3oook, digikey has it listed as CXA3070-0000-000N00Z230F-ND. I'm unsure how to discern bin numbers, does that listing number tell us anything. Planning on mounting it on the 5.88" x6" long heatsink. I've never seen a cob this big, is it mounted on a star or do you just sand the heatsink flat and mount it directly with adhesive. Basically, is there any prep to mount these large cobs? Also, this cob is gonna fill in some dark spots to supplement a 1k hps lamp, so would you recommend running a softer mA like between 700-900? I guess I'd like to run it about 30 Watts since that will match the heatsink size. Lastly, are there any good links to video tutorials putting these together?
Thank you for your help:)
