How often would the bulbs have to be replaced?

Ideally, 9 months.

What about metal halide? I found a lamp that includes 1 metal halide, 2 blue t5 and 2 moonlight LED. Could this work? http://m.ebay.com/itm/MH-30-Metal-Ha...916?nav=SEARCH

IMO both fluorescent (T5) & halide lighting components will become increasingly difficult to source in the future and as a result, more costly. Plenty of reasonably priced LED fixtures available these days to grow any coral you wish. My DIY LED rig has been running just short of 5 years (April 2012) & I certainly don't miss the bulb change hassles from when I ran a hybrid halide/T5HO light monstrosity. Furthermore, halides are a source of excessive heat, which you may have to mitigate with a chiller - more costly hardware adding to your hydro bill.
