I ran the reef breeder Photon 48's and they were mounted 12" above the tank with no problems. I was told by the rep that I could go 1-2 feet above the tank and adjust the intensity. My tank looked good and grew everything nicely for the near 2 years I had it. In the beginning when I switched from t5's I had to lower the intensity to a max of 56% for a hour and gradually rose it to a max of near 74% for a hour a day in the end. The average intensity was at 54%. It will really depend on where you are putting your SPS in the tank and the tank depth.
