Is a 480 Watt T5 system going to be strong enough for that large of a tank?
I'm a MH guy...I love the shimmering look you get with the MH's and IMO the PAR is much better with MH's especially as you get deeper into the water column.
And after a lot of research and discussion in another thread under Advanced Reefkeeping....the research I have found is that you MUST be sure to change the bulbs annually in order to avoid severe spectral shift in the wavelengths the light is producing. And you need more T5 bulbs to acheive the natural light level that we all try to reach in our tanks, whereas 3 MH bulbs get a lot closer to natural light.
Also, the MH bulbs, after research are found not to have a spectral shift, but only lose PAR.
Just my .02
