I would say that husbandry would be the limiting factor in what you are able to keep, not lighting. If you use high quality bulbs, ATI for example, you should be able to keep just about anything that you want.
I typically run less light on my tanks than most other people, I run a 7 bulb T5 light on my 150g tank. Even with acropora towards the bottom of the tank, the growth is above average.
