Make sure that when you DO get the lights that you do not overexpose the corals to that light! Start with the corals very close to the sandbed and work your way up with them over several days, if not weeks. If not, they will bleach and die. Each coral will have a spot that it likes, and it will reflect in the growth, polyp extension, and coloration of the coral. I would also start with a few hours less light for the first three days.
