The bulb on the left has a CRI of 80. The bulb on the right has a CRI of 92. An incandescent bulb has a CRI of 100. The color rendering index (CRI) of a light source is a quantitative measure of its ability to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source.

my logic would say higher is better ,, ie closer to sunlight... but im no expert

@Dudeski @BigSm0
OK so now the 1812, 1818 number? I know bigsmo likes 1812 but I didn't see any in Stock when I looked yesterday. I'm guessing he bought them all lol.

Yes, its better but big has to explain why. I will say, ive built 2 but i will be getting one of the autocobs being sold. For convenience, all the work has been done. I can plug it up and let it provide life to our beloved canna plants!
