Back in the day, people used PC
bulbs to keep corals...but they needed many of them over a tank to meet the requirements for photosynthetic creatures.
If you want to be successful in keeping coral, I'd suggest a higher output lighting. Even a 2 bulb T5HO unit can successfully keep soft corals. I normally suggest the LED
route as it is cheaper and normally once someone gets bit by the bug, they want more light intense coral and anemone. If you want to keep any photosynthetic anemone in the future, you will need as high output lighting as you can. Either 6-8 bulb T5HO, MH
, or LED
