CRI and K numbers?

[canibanol cannonball]

:confused2: What do these stats mean? CRI:90 3100K? i know they differ from light to light.

CRI is light feed back value... I do not know what it does though... 3100K is the colour heat of the light which indicates the spectrum it is in.

google = CRI is 8 spectrum of light on a 0-100 scale. CRI of 100 has all light spectrums. CRI and K are "roughly" the same thing just two different ways of reading spectrum output. Thats what i can make out the math is hurting me
