Three Fluval fixtures would put you on the high end of high light. Two would be sufficient but you would definitely need to dose ferts and use CO2.

What are the dimensions of your tank? How many inches from the substrate will the light be placed?

As BruceF suggested, daylight CFLs are a cheaper and more reliable way to go. You can use a desk lamp or clamp-style work lamps from the hardware store. Bulbs are cheap and last a long time.
