it would allow to run pretty cool, and probably very close to the canopy. I saw a thread on RIU about some alibaba sellers qb copy with 800 diodes. It was 30x90cm if I remember right, and some guys in the thread did cover their entire grow space.
Everyone in the thread seemed very happy with their results, though I doubt the diodes are legitimate. Just the board was something like 70$, and covering everything would probably allow you to run it soft enough to forget about heat-sinks. Might be a great solution for someone who does not care what diodes they really get, as long as it works. For me even if I'm not using the most efficient leds, I can calculate their output pretty precisely.
If your not limited on budget, there is hardly a better solution then covering the entire canopy evenly with the most efficient leds on the market.
I would love to do this in my MMJ room. Has anyone done this? I'd love to see pictures and PPFD mapping results.
This is effectively what I've been promoting with futuregrow, to apply 50w per square foot with high diode density for big light and big efficiency... A modular approach using one board per square foot.
One of my customers runs four of my 400w luminaries over two long dwc bins, covering an area 2.4m x 1.2m edge to edge with diodes... 32 boards with 320 diodes each, total of 1600 Watts.
This setup is going get some crazy results.
I already did the ppfd mapping for this in a 1.2 X 1.2 space. Can send you the results if you're interested. I posted them up in my original thread a few months back.

I'm surprised more companies are not going for the whole 'cover the entire canopy' approach. I imagine you would have different diode densities for different target ppfd's. 200 for salads and herbs (main inside crop) etc.
