Here are the results, using an Apogee PAR meter with the extended range sensor.

Average of 992 PPFD.
STDEVA : 303

Could we say it's uniform?!? The led fixture was just a bit offset to the right, which explain the 512 vs 332, 575 vs 403 and so on.

I think I found the issue (another post from me).... Rh controller was offset so RH was way too high, it should pop shortly!

001.. LOL 3 weeks... (i lost a lot of veg time because of rh out of whack)

003, same system hps light DE 1000 watts (1090 watts at the wall)
004, same system LED... (1010 watts at the wall)

006, what's left to say...

I will NEVER grow with hps again!

Yeah, I think it's too powerful for the plants.. I THINK I may have some light bleaching starting... I'll try to take some pictures tomorrow... Will have to dim/raise them.. but nice! if I can dim 20-30 or even 40%, that will save a bunch of electricity... Just pump up the juice when going in full bloom mode (as long as they can tolerate it of course)

I did another PAR test @ 24" from the fixture.

Average of 834 PPFD and a standard deviation of 243. It is more uniform at 24" vs 12"

PAR test @ 38-40" from the fixture on the 1k HPS DE... (ok the bulb is used, 3-4 runs i think) but just for fun...
Average of 645 PPFD and a standard deviation of 67 (which is quite nice though) but LED vs hps... wow!

I could run the led fixture at 12 inch and dim a bit to avoid the light bleaching... I'm not sure this is it but seems to be.

Is it better to mix deep red and red?

@Have2
Im currently on a similar build. Your thread was helpful.
Did you wire these in series or parallel?

Hope your beast is yielding as expected??

I wired them in parallel. As for the yield... Crazy
