Efficient? Yeah, LED's and CFL are both relatively efficient light sources.
Not sure you need those Blue's in your LED spectrum. All those CFL's (and your White LED's) should cover your needs. Tbh, with that much CFL light I'm not sure you need any White/Blue at all from the LED's, you could go 60%-40% on 660nm-630nm and probably be fine.
Why are you going with CFL, anyway, as opposed to more LED? Cost?
in addition to mixed spec cfl's @ 400 watts total
660nm,
630nm,
460nm,
440nm,
whites
(3000-3500K),
(6000-9000K).
on a 300 watt panel and do you guys think the results of 400 w cfl and 300 watt led of that color be efficient ?
