I just saw a very extensive chart w/ lumens, watts, heat & distance NOW I'm like wtf? At that rate how does each plant still get its neccesary 5000 lumens? most cant even put there 1000s that close? & say you wanted to get your plant more than than sufficent lumens, let's go with 8000 then you gotta drop the light ultra close, unless you have less then 2 ft. Of plant height, & by dropping that low you lose more sq.ft that you can light. But then I see some dudes lighting hugeee spaces with a single 1000 like 5x5+ what's the real deal here? It all seems so misleading
