Not sure what you're asking here. What kind of ballast is it? If its like one of mine then I have 2 lights plugged into one ballast, with 2 ballasts for a 4 PC system.
It's one Dual output 65w PC ballast by Custome Sealife, Inc. What I really want to know is why is one bulb a 55w Daylight and another a 65w Actinic, and not both 65w...
