T5 lighting for SPS?

[bignose]

I'm using a 6x54W and had the same question before I bought mine. From what I read on the interenet you can grow sps but near the top of your tank. The person I bought the light from had sps under the light and he said it was ok. I'm relatively new with sps so I'm guessing some of the lower light sps. I don't know which ones though.

Perhaps someone could throw toss some answers here? perhaps? please? hehe.
