yep every little bit helps, even the low lights that don't get alot of light still get some and for mushrooms it requiores very little light for that reason, because they usually live in the deeper parts of the reefs where more of the light is filtered out but SPS
require more as they are higher up and closer to the surface where less light is filtered out and more red and green spectrum waves are present
thats why alot of the times we aim to use daylight bulbs and full spectrum, a reasom why KZ fiji purple is suck a great bulb. heres a link to a comparison of the purple plus and fiji purple. you'll notice the full spectrum and the spikes in blues greens and reds
