IMO the Nova Pro series is sufficient for SPS, depending on tank depth, higer placment maybe necessary. Although not parabolic they have individual reflectors. However I will argue that if you have the extra $ to opt for the aquatinics or Tek's with true individual parabolic reflectors and you will indeed be able to keep what ever you could keep with MH lights matching wattage. Although your up front cost maybe close to MH in the long run its cheaper. JMO. And if you over drive them IMO they surpass MH. Again jmo.
