Thank you, that was helpful. The only problem is that I am looking for the spectrums for marijuana stages. I think mj is differing slightly from that graph and also the stages determine the amount of usable light spectrum (i.e. more blue during veg for rooting, more red/orange for flower). It's hard to give a generalization for plants with the amount of lighting prefernces, intensities, etc. and the fact that blooming is at different times for different species. One major benefit of corals is that although there are thousands of species, generally the lighting is the same(a little more shade here and there, a little more depth for some) but lighting stays relatively constant once you have it set up. Now when I say constant, I don't mean the cycle must be constant(I have a variable lighting program for my LED setup including random cloud cover, waxing and waning moonlights, dawn and dusk cycle, variable day length, etc.), I merely mean that there are no separate stages of their light cycle.
