That gives a great visual of how the lights project out and with the HLG Scorpion Diablo, you can clearly see how the PPFD from the 3 modules crosses over to cover a larger area. I always thought 3 smaller lights would give better coverage than one large cluster of LED's. Later I would like to do a comparison between this sites PPFD maps and the manufacturers.  

It looks like the Migro Aray 4 Pro would be perfect for a 2 x 4 tent,  I've never heard of them though. Has anyone else heard of them

What I dont get about the PPFD maps is none of those HLG lights put out PPFD in the 600-1000 PPFD range to cover much more than a 3 X 3 canopy without cooking the middle of the canopy, but I have seen  pictures of some really awesome grows under HLG lights. How does that work?
