what about the larger versions of the sfiligoi? I am considering the 8X80W unit as it would be cheaper than replacing 14 29w bulbs in the constellation, and you are getting a higher wattage? This unit has active cooling right? What are the quaity of the reflectors like in comparasion to the Aquactinics? What about the ballasts? Can anyone tell me? they are very close in price to each other.
