the charts i looked at are showing hotspots or uneven coverage at lower heights with the 650r and diablo scorpion . with lights raised higher the ppfd is more evenly diffused, it seems 28" to 32" is the sweet spot for the 648 boards it looks like.

  I agree, and who would lower their light to 6" above the canopy and why would they? Seems like to much light is worst than too little so I set the light to make sure that isnt a problem first and then check the outer edges. I think lights with bars is the future of LED's so that is what I am looking at.

  either/or , anyways , light spread out/diffused evenly and as efficiently as possible is our goal i believe. whether it's bar lighting or spread out like the scorpion it is definitely the route to go over the quantum boards i believe. quality of diodes and spectrum is very important too.
