Generally higher output will be better than micromanaging the spectrum for growth. I wouldn’t worry about it, there isn’t going to be a huge impact. Yes some spectrums are more efficient, but that is at the same output levels and I have not seen evidence that it’s a dramatic impact either way. More a theoretical thing for our purposes when talking about small potential increases.
it is good for refugiums, just not a necessary spend. I love kessil but I can admit it's generally overkill for growing chaeto. I'd set it to whatever light is most pleasing to your eye and adjust the intensity as needed. I use the kessil H80 for my display fuge and leave it on "grow" mode on the dial.
Its not that it isnt good for a fuge. I just dont see why all the lighting/fuge/ats manufacturers jumped on the bandwagon. Kessil really confuses me on this. Kessil made horticulture lighting long before they got into the aquarium game. They know lighting. I am just a guy with a bunch of plants and fish tanks and I had a 75g display fuge on my last system that was very nice. My current fuge is so overgrown with caulerpa and dragons breath that I hate how it looks but function over form on this one I am running a 96 cri 7200k light on it. They may know something I do not but I can speak from experience high cri white light will grow macro better than the pink light. But that a360 will be fine for your cheato.
