you are alot of lumens away from having enough...............let alone to muchI'll be doin an experiment later on this month. Just 1 or 2 plantizzles. I was going for a pyramid light set up. so im looking foward to 4 - 26w flo lights with 1700 lumens and 2700k. and 2 - 86w flo lights with 4200 lumens and 6400k. sound good let me know.
I googled it and it's 10,000 lumens per square yard.I figured more considering how bright it is but then I thought about it and any given point it's not that bright but on a big scale it is.sun puts out 10,000 lumens on a clear summer day
