It is something that Dana Riddle has written about using Porites. It is a good start, but there is still way too much real life experience that contradicts what he is saying, especially with Acropora. There are all kinds of control issues and assumptions that are made between different types of "coral." You can search for his many articles - Google knows how to find them. He lays out his tests and the equipment that he uses and you can make your own assumptions. All that I know is that I grew Porites in a fuge under a 60w incandescent bulb, so they are not all that demanding.

I run my Halides for 11 hours, on and off with a light timer. I have 250w HQI, so about the same output as a 400W Radium. The 11 hours gives me more growth and color than 8 hours... all that I need to know.
