I have the option of less efficient 3000K led or more efficient 4000K Samsung leds.
So I superimposed two relative colour spectra. But I see no significant departure between those 3000K and 4000K spectra in terms of 680nm+ relative output. Sad Emmerson.
3000K = RED and 4000K = BLUE

3000K LM561Cs spectrum seem subractive somehow. I have compared the PPF between 2700K (131.14 µmol/s) and 4000K (126.73 µmol/s assuming 165 lm/w @ test) which supports the 4000K pumping out more photons.
Tho it wouldn't surprise me if I'm reading this wrong.
