Package expected delivered Wednesday from KingsBrite.

@BigSm0 what is the optimal distance between the 1212 COBs, and how hot would they be at passive heatsink?

Figured out a different mount material

Heat will depend on how hard you push them and I would imagine the optimal spacing would as well. How many watts will you be running them at (each COB)

I'll run them at 50%

At 50w each you should be good with 12" spacing. Adds up with 4 cobs on 4 foot bars. The heat you notice of feel depends on your heatsink. The total amount of heat won't change though. 200w of cobs is around 400btu of heat.
