10 x Samsung (LC080D) COBs: $170
2 x Meanwell PSU (HLG-320H-48A) $132
10 x 150mm pin fin heat sinks $115
the LC080D COBs seem to out perform almost any other popular COB i looked up. and i was limited in the one i could actually purchace because the one i really wanted yo had to buy 1000 of or something haha. I made it into 2 groups of 5 COBs for the driver so that it is drawing ~1.23A and has 50.7V actross each diode all being in parallel the specific COB ended up getting is SPHWHAHDNM231ZT3D2 so it is only Gen 2 but with all together according to Samsungs LED calculator
