I think most people keep it on when your tank lights are off? Helps with temp changes from lights. But I've also heard of people running them with the normal light timing. Usually people throw a fish or invert down there so lights won't be on 24/7 but probably pretty long to grow some good stuffs

I'm pretty sure it needs some light. But it seems to grow under rocks and stuff so it might survive under like fluorescent lighting?

It's often turned on at night in what's referred to as a reverse daylight photoperiod. It helps balance pH. At night just about every living thing in the display tank takes in oxygen and produces co2. CO2 in water forms carbonic acid and any acid in water lowers the pH of the water. By running the refugium lights opposite the display tank you let the plants and algae in the sump take the co2 from the display tank and convert it back into oxygen. This makes the pH more stable and keeps oxygen high when it would otherwise drop. Keeping the lights in the sump off during the day helps control heat and is good for the copepods. They're nocturnal.

Cheato works well with a simple cfl bulb in a cheap lamp.
