Yes. And the limit is what your corals can stand. Your corals will let you know its too much but why do you ask?

Something make you think you have too much light?

Going from PC to MH you'll def have to ease your corals into the new lighting. Either move your corals low in the tank or hang those lights high and move them down a couple inches every week.

You wont mess anything up, you can do few things that are super easy. Either a) raise the light higher slowly lowering it week by week b) shorten the photoperiod to 6 hours and increase 1 hour a week or c) use some egg crate or screen under the light and remove a layer every week or two.

I went from 4 t5's to a 150w over a 29g with no light acclimation and everything did fine so i wouldnt worry too much or anything.
