hey @sixstring do you think this is enough heat sink? it's a rapid led pn-140mm (x2) vero 29 gen 7 cobs one each and a meanwell driver hlg-185h-c1400a. if i figured it right it should be around 200w total, but i'm not sure how to figure the heat watts.
yeah i would use 160mm heatsinks for those cobs,should be good to 100w passive that wayif i remember right they are 69 or 70 volt. i'll look for some bigger heat sinks, this is still planning as i'm still playing with my air cooled at the moment.
