the higher the cri the more even the spectral output and better the performance. I've seen first hand. My inda gros put out 800 µmoles and has 95 cri and out performed leds putting out 1100 µmoles at 80 cri. Imo cri trumps over par. If both are high like CMH then that's even better l
No they don't. Relative to itself the 90 cri seems really nice. Put it into absolute power(non-normalized), and the 80cri has just as much deep red, but more blue, normal red, and yellow. So proportionally it's different. But the absolute amount of deep red is damn identical, then count in what you're losing.Wait, what? Your second and third sentences contradict one another.
Are you referring to HPS when you mention counterparts or 70, 80 CRI LEDs?
I have posted the graph a million times already and will post again when I get home. The spectral gains are nothing compared to the output loss.
And please show me where it actually shows deep red is more photosynthetically active that orange/red?
EDIT:
Here is the graph showing what you gain and what you lose...
