And Phat, 5,000 lumens. How far from the plant? Lumens is a measurement of the light people see, not plants. But Iā??m sure you knew that. Is that close to what the plant sees at those nm?

-----------

5000 lm @ 16" to 18" with 2'x7' coverage=$1822 not 4000. (2' wide because of walls)

Just telling you what the tester reads if you think i'm wrong so be it.
