I think you'd need a new ballast that would run them as high output.

Look for a workhorse ballast...with at least as much wattage as the bulb you want it to power. The high output ones say "high output" or "high power factor" on them. Premium aquatics has some workhorse (http://premiumaquatics.com/store/merchant.mvc?Screen=PROD&Store_Code=PA&Product_Code=CI-00277&Category_Code=) 7's on clearance.

I've ordered them from prolighting (http://www.prolighting.com/woba.html) before. Prolighting.com is in Michigan, but only do mail order.

no you can not combine a 2 bulb ballast that runs NO to make a 1 bulb HO you will fry the ballast as it is not designed for this

get a workhorse 5 ballast they run about $25 and save yourself the hassle and have a 2x 54w fixture

oh yea workhorse ballasts can be found at any good electrical/lighting store
