The Keystone ballast was working properly when I installed it. Unfortunately the location of the screws securing the ballast to the ceiling panel was not exactly the same as the old burned block. This involved finding some washers and some longer mounting screws to hold the ballast on both ends. However, when I installed all of this, everything worked. I ordered two so I have one on hand in case one of my hallway lights burns out.
