reef165 Posted January 12, 2011 Share Posted January 12, 2011 How many watts is it rated to run? The 48's are 110 each and the 36 is 75 I think so you will be trying to run 405 watts, as long as the ballast will run that many watts then your good. can you see the actual ballast or is it in a housing?
