Abstract :
Precise aiming of floodlights is one of the secrets of successful sports field floodlighting. Each of the hundreds of lights must be directed at a slightly different spot to illuminate the play properly and at the same time to keep glare from the spectators´ and players´ eyes. Here the packing boxes in which the lights originally were shipped from the Westinghouse Electric Corporation are arranged on the Polo Grounds of the New York Giants according to a predetermined plan to act as targets. A rifle sight built into each light makes it possible to aim the lights in daylight.
