you can use T5ho for SPS just not for all you would not be able to do shallow water Acro's but deep water Acro's would be fine as long as you put them high on your rock work also Monti's and Digita's would be fine. just the ones that require specific lighting would do poorly. forgot some Millie's will do fine also.
If I got this unit I would install fans as I believe this light does not have any. Not a hard thing to install. If it has fans then it should do fine. you could always DIY it make a aluminum frame and mount everything on it you could then add a MH fixture latter.
