I would guess you could keep a montipora capricornis under that lighting but it wouldnt show its best color and wouldnt grow as fast. I am keeping monti cap under PC lighting but its almost 500w and its placed about 8 inches from the lights centered under my high noon supplemental light. but I think your below the safe range for most SPS there are a lot that wont make it due to the extremly high light requirments those corals have. However I am not an SPS expert, while I do keep more than just MOnti under these lights I have a very very strict regiment about feeding and maintinence so my parameters are ALWAYS exeptional. keep in mind that when your keeping something at the lower range of its light tolerance your going to need to make sure it gets benificial feeding from whatever food source it needs be it plankton, rotifers, oyster eggs, or whatever. before you get them make sure your ready, under iffy conditions its hard to stop the decline in health once it starts.
hope this helps a little.
