Citi gen5 90CRI spectrum better than Citi gen6 90CRI spectrum?

Hi guys! Give a look to the Citiled 90CRI spectrums gen5/6 and compare them. I see a difference of ~10% more for the gen5 in the 660nm range and around 5% more in the far red range for gen5.. what is your opinion about that? Gen5 or Gen6.. more red or more lumens? I ask because for me the main reason to buy a 90CRI is the red/far red zone.. nothing else!

I would agree, I prefer the gen 5 spectrum but the 600 to 700nm range has a very high quantum yield so the difference in spectra would likely have a negligible difference.

Me too I prefer the gen5 spectrum - let's say it's a bit like "six of one and half a dozen" or "tomato and tomayto".. but I prefer more red when I choose a 90CRI - photon flux difference/% seems to be less important than the red/far red zone difference/% in this case... especially in the 660nm range.

its been discussed, and the consensus was that the increased efficacy of the gen 6 offsets that difference. remember those spectrum curves are relative and normalized to 1. multiply the gen 6 curve by 1.05 and compare it and you'll find the area you think is reduced at higher wavelengths is not reduced by as much- and the gen 6 is considerably higher across the major 580-630 range.
