So it barely beats DE HPS? 1.82 PPF/W...? I know DE isn't anything to sneeze at but Bridgelux, Samsung, Citi, and Luminus all put out much higher umol numbers. Cree's competition in this market is something like a Vero 29 Gen 7 Type C @ 50w = ~2.83 umol/J. Even BML's SPYDR fixtures put out better numbers and they have been out for a while.
They threw in some 660nm reds. Big deal - green is more important at these PPFD intensities anyways which the 4000k in their engine has plenty of.
Instead of spending time on this, maybe Cree should have been working on the successor to CXB3590.
Basically the selling points to this is that it is passively cooled and has uniform PPFD. In that case, skip this and go the quantum board route; you'll have better results.
