How would you light a 6ft tank?

My tank is 24" deep and is SPS dominant. They are 2-250 watt single end on electronic ballasts. For an LPS/softie tank I would suggest 150 watt for your 20" deep tank, but you would need three to span 6 feet. You would need to buy your lighting used in order to stay under $600. Most of my LPS do not like the 250 watt halides and have to be placed off to the sides and in the shade.
