High output is correct, any good lighting supply shop should be able to get the bulbs you need. Tri-State in Winchester Va has supplied all of the bulbs that I have needed, now they go by Hagemeyer-TriState. They may have a store in Manassas. Good luck! Brady

The ballast will probably cost about $75 bucks. I think I have a spare one in the garage. I have several light up canopy signs.
