Hello: Plants have at least two variations of chlorophyll. If I recall correctly, each will operate to capture light and change it into chemical energy (sugars) that the plant uses for life processes. Sunlight has a full spectrum of light, only some of which the plants can actually use. The light colors across the spectrum are measured by us in wavelengths that we call frequency. The longer wavelengths (lower frequencies) are at the red end of the spectrum and visible light increases in frequency (wavelengths becoming shorter) across the spectrum to the blue end of the visible spectrum. We only can see a small segment of the total light spectrum.
Plants use light frequencies best in a couple of bands of the light spectrum. The rest of visible light is of no value to them. The colors that plants do not use are the colors that plants leaves appear to us. Mainly in the greens. Plants absorb the colors they can use and reflect the ones they do not use. We see what they do not use.
Daylight, natural, brite white and broad spectrum bulbs tend to have a lot of spectrum to sort of mimic sunlight. I like brite white or daylight bulbs at a frequency up to 6500k (K is the numerical symbol for frequency) I think this means that there are a lot frequencies included, from reds at the short end of the visible spectrum thru toward the more blue frequencies. Some bulbs can have frequencies higher into the blue range up around 10,000 k or so.
If you used bulbs that only put out green light frequencies the plants would be affected the same as being in the dark and could not live.
You could use plants spectrum bulbs that would grow healthy plants but the tank would appear dark as the plants will be absorbing much of the light and reflecting little.
I like to use a natural or brite white bulb that has frequencies the plants can use as well as plenty of other frequencies to be reflected to my eyes and make the tank look good.
I hope that I got this mostly right from memory. I did not put in the frequencies and temperature ranges the the chlorophylls work at because i am not sure what they are from memory. I think some of them are in the reds.
