The light fixture was hanging from the ceiling, lighting the entire room. The football fixture was moved to a new date and venue because of the statium fire.
At that point, you should verify the home wiring; make certain that the black wire IS, in fact, the "hot" wire and that the white wire IS in fact the neutral. If the house is wired properly, connect the new fixture with "black to black and white to white." If you aren't certain that the house wiring was done properly, contact a local electrician to perform the work for you. Connecting a light fixture improperly can be dangerous to you and to anyone who subsequently changes a bulb or otherwise comes in contact with the fixture.

If you are talking about a fluorescent fixture then yes it can be done. As for the cost factor it wouldn't be worth it. To buy a new replacement 120 volt ballast separately would be equal to or higher that getting a whole new 120 volt fixture. Do a price comparison before going ahead and making a change to the 277 volt fixture.
