Yes, that is correct.
The spectrum chart provided on the data sheet for that model indicates adequate red.

That has yet to be determined;-) ........remember almost HALF of the spectrum is between 500-600nm......dat green gap is a bitch on most "white" sources. When the very high lumen per watt all white led panels release it won't matter though IMO.

I think what ever has a higher cri, ie more even spectral distribution will do best. All white x-te's should do very well

I said MOST "white" sources.......wow, big difference in spectral distribution.....valoya looks great on paper, do you know the leds used in the fixtures??? or can't say because the boss will kill you......lol

edit.....does the valoya graph represent their NS2 full spectrum white guod??? because if it's with dedicated red emitters, this doesn't really surprise me...........oh it is the ap67^^spectra! well that's not really fair to compare against an all xt-e 3700k panel you devil!:fire:

Yeah.
if I had a degree in botany....and a lab.
it is funny though how one chart shades the spectrum dif than the next...indicates MORE red or not....
i would love to have access to a lab with all the right tools to do a proper analysis on spectrum affects on chlor and other plant processes....BUT in the absence of that dream, we can say that if a panel can take a plant from seed to harvest with the spectrum provided and produce acceptable results for the HOME gardener then....it is all good.

As far as the green, is it really THAT important?
the fact that a plant os green means it reflects green light.
so how much of that green is actually contributing to photosynthesis?....or other processes?

For the record...I am not financially or emotionally beholden to any light brand, although I do own a A51 190 and all indications so far are good....same as other brands out there.
I am however very adamant about LED viability for the home gardener.
