Just trying to wrap my turnip brain around interpreting spec sheets
So take xpe2 warm white 2600-3200k, run at 700ma:
bin Q4 not rated for cri shows highest flux at 171 lm
higher CRI drops flux output. 90cri bin p4 shows 138 lm
about 24% higher lm output from the Q4
As CRI number increases, relative flux decreases
I know lumens are not representative of usable light for plant growth, but is this comparison valid at any level for our purposes? Seems to me the Q4 bin has better efficiency.
