I applaud you for the work that you went to detailing this side-by-side. The only thing is, I have no way of knowing if the differences in the 2 sides were due to color temperature or cri. I suspect that the color temp may have had more to do with the slight difference in how the plants grew (much more blue), moreso than the cri, but that is just a guess.
While the lower cri cobs will always beat the higher cri cobs on a lumen meter, since they have more of their energy at 550nm, I suspect that the overall par readings of the 2 are probably close. But until someone like
@CobKits, or his Clark Kent-like friend
@BOBBY_G, does a par comparison between 2 chips of the same color temp (high and low cri), we can only speculate.
