Took you long enough.
If you want to run t-5 you should be able to get away with a "QUALITY" 4 bulb system. Look for individual reflectors as a must - they give better output because they direct more of the light downward where you need it.
If you want to look into LED prepare to pay $$$ up front. There are many good points that will equal out over a period of time such as possible energy savings and bulb life (you won't have to change out bulbs every 6 months or year). I purchased one of these from txg8gxp and bought another one from the vendor - http://www.evolutionledlight.com/
There are way too many variables involved - positioning of coral or clams, quality of fixture, and what type you decide on. Also, do you plan on leaving the glass tops on? If you go MH then that could cause some heat issues.
