This might tickle your fancy. I don't know where I got these PPFD charts from exactly, but it's taken from a 20x CXB3590 setup over a 4x4' area, at 511w totalTo reach the best efficacy ppfd/w
49cob on a 4' by 4' metal plate
no heat sink no frame
490 watts dimmeble to 245 watts
Ill be able to keep the cob at about 4 inch to 6 inch and get the best coverage and high umol at the canopy with low wattage just to build the best !

Here's 12" distance
24" distance
Pretty damn uniform, and the efficacy is decent. If he wired it all so each cob was at 350mah though, he'd go from 156 lumen/w to 177 lumen/w. Or maybe he mislabed it with 700mah, i dunno I need a coffee lol.
Strips blow that out of the water in terms of uniformity though, and mine run at the samne exact 156 lumen/w after driver losses and all that shit. And it didnt cost me $2000 lol.
