Hello HydroMan, I've done a little more research and basically what I've learned is:
The white leds are a bit better (like 3% more effective per watt) then florescent but the point of LEDs is the use the targeted wavelengths (red blue ect) that the plant your growing needs/prefers (making it more effective per watt used). White is the lest effective color (look up "PAR" ).
Some plants like marijuana can do well with just red/blue LEDS while others could use a 3rd-11th~ wavelength.
I've got half my grow box in red/blue (100x1w leds) and the other half with warm/cool white (100x1w leds)
led's I can't really tell a difference but the
lights kinda mix.
*I'm growing dwarf tomatoes and peppers in a 4x4 box not the most light depending plants.
