On October 12, 1977, a new energy-efficient lighting system was installed permitting a wider range of colors. It was inaugurated with flashing blue and white lights, announcing that the Yankees had won the world series. This installation uses metal halide lamps plus 310 fluorescent lamps. Plastic gels are fitted manually over the metal halide lamps, or floodlights, and colored plastic sleeves are fitted over the fluorescent tubes in a variety of colors to honor national holidays and events of interest to New Yorkers. The lamps create candle power of 1,000 watts each.
