LPS corals usually have low light requirements and I find many people seem to think they need tons of light like SPS corals. Whenever I've been diving most LPS corals are in deeper waters or in crevices and some of the best LPS tanks I've seen are lit with simple PCs. My first tank was mostly LPS and was lit with a combination of NO and PC, to this day my LPS have never done as good as they did in that tank.
