yeah, 4000K CRI 80 is quite similar to 3500K CRI90. more shifted to the left (and therefore less red)

btw where do you get 90CRI LM561C?
I got the 3500K/90CRI precisely assuming a stronger shift to right. The previous table shows just that: it shifts to the right, and spikes higher on the left (compared with 3500@80). Now that I know this I might turn 100% of these strips on for the first week or two of flower and only half of the 3000@80.
I sourced the strips from an Alibaba supplier, Mufue. Meijiu and Bright have 3000@90, but only had templates for larger PCBs (no hardware store aluminum-profile heatsink) or simply cost more.
