Abstract: A floodlighting system for one or more tennis courts utilizing a pair of high-level floodlamp supporting structures adjacent a diagonally related set of corners of the perimeter zone of a tennis court. The lamps on each support are directed onto the adjacent back court and service box of a related court and uniquely aimed to be highly effective in illuminating the advance face of the ball with increasing light intensity as a ball in flight approaches a receiving player. The height of the lamps together with the small included angle of its beam greatly minimizes if not entirely avoids glare in the player's eyes. Adjacent courts are effectively and efficiently illuminated by lamps supported on a common pole located at the junction of a contiguous pair of court playing areas.
