fluorescent lights put out a full spectrum

the difference is the intensity of light is not the same across the entire spectrum.

The sun puts out full spectrum which means all the shades of all colors.
Full spectrum florescent bulbs put out specific shades of blue, yellow, red,
and green. So whereas the sun would put out 100 shades of green a florescent
bulb will only put out 3 shades of green. Plant lights put out mostly blue
and red and normal office lights put old mostly green and yellow (what
humans see best)
