You're conflating two concepts, color temperature and CRI. Together they roughly describe the spectrum output; color temperature tells you where the peak output is along the black-body temperature line, and CRI tells you how lumpy the response is. A low CRI can lead to metameric failure[1]. [1] https://en.wikipedia.org/wiki/Metamerism_(color)#Metameric_failure https://en.wikipedia.org/wiki/Metamerism_(color)#Metameric_f...
