assuming those are gen5 chips, graphs on my site for 3500k:
80 cri red peak is at 600nm with little output over 680 nm
90 cri red peak is at 630nm with substantial output over 680 nm

Hey Cobkits thanks for those.
Exactly what i thought, more deep reds. Its interesting to see it having it's effect in veg alredy, while a lot of growers start using more reds in flower.
I just bought 2 red meat 1211 cobs from lumileds, and I am more than ready to give them a try in my next grow to add as additional lights. I also got 2 'marbled meat' cobs which also bump up the blue and the red peak is
even more shifted towards the infrared range, they almost look like blurple but still white.
But the efficiency is not that good at all, allthough I am not sure if all is measured..:
However the spectrum is unparraleld
Possibly even too much far red with the marbled meat cob!
I am planning to use 2 red meat cobs in a grid of 15 cxb3590cobs in total over a 3x4 space, thats a very small space for so many cobs but I wil run them without lenses at low amps nice and close to the canopy to maximize efficiacy.
so 2x red meat
4x 4000K 80cri
1x 5000K 90cri!
3x 3500K 80cri
ànd
5x 3500K 90cri Cree!
CXB3590-0000- 000N0UBD35H
But NO spectral graph of those to be found anywhere, so I hope they have that little extra deep red I am looking for and not just more green... Possibly it would have been better to have gone with the 3000K 90cri...
keep up the awesome experiments guys!
