1. A method of playing golf at night on a golf course comprising:

  • providing a glow-in-the-dark golf ball having a high illumination contrast with a dark exterior light level;

    illuminating only predetermined spot locations on the golf course and various hazards of each golf hole on the golf course;

    providing illumination units each having a light beam for illuminating said spot locations;

    maintaining the golf course, other than the illuminated predetermined spot locations, substantially unlit, so that substantially the entire fairway on each golf course hole remains unlit with a dark sky backdrop and a dark ground level, wherein each fairway extends from a tee location along a central axis to an associated golf green;

    illuminating said spot locations with the illumination units while the light beams are directed away from the fairway central axis; and

    playing golf with the glow-in-the-dark golf ball while only the spot locations around the perimeter of the golf course exist in an illuminated state thereby allowing the golfer to identify discontinuities and hazards in the golf course while at the same time maintaining a constant sharp illumination contrast between the glow-in-the-dark golf ball and the exterior light level along a standard flight trajectory and landing path for various locations on the fairway.
