While it isn't as simple as saying SPS = high light, LPS = medium light, and Soft corals = Low light, we know that there are multiple corals in each category that favor different lighting. For instance, Leptoseris, although it is an SPS coral it will do best under medium-low light. A soft coral like the Fiji Yellow Leather will look its best under the most light you can possibly give it. I would say that branching SPS like Acropora, Stylophora and Bird's Nest will do well in your higher light areas whereas Micromussa, Euphyllia, Favia, and most other LPS will like the middle of your tank, and the area on the bottom middle. Most Soft corals like mushrooms, toadstools, and others will enjoy the lower end of the light on the sides of your tank. Just keep in mind that although the light might be ok for that type of coral, the other major aspect to consider is if the flow is ok in that area as well for that coral.
