Those numbers can help you decide how close the light can be to your canopy, if you didn’t know. “According to science 1200 uMols is just overkill” – You post yours, I’ll post mine:

Numbers are important, much morose than you guys seem capable of understanding. Even when you grow, you need to collect the ‘numbers’ – but you guys don’t, lol. You just grow plants, take pictures of them, weigh the bud at the end, and then boom you think you’ve conducted a scientific experiment. Lol.
Why do you think efficiency is only related to PPF? You don’t think a fixture’s PPFD score is relevant to the overall ‘efficiency’ of its efficacy? You can put these fixtures in a sphere and note the total photon output relative to its power draw all you want, that metric isn’t the most important by a long shot. I will say it again, designing lighting systems is about
distributing photon output. Hence the ‘D’ in PPF
D. The efficiency of the available diodes on the market has nowhere near the variance that the efficiency of distributing photon output has in the market today.
I’d consider switching to a fixture with a 37% lower PPFD score to be a “wasteful practice” – but that’s just me.
They are expensive, for what they are. That’s why their price got beat.
