Stadium lighting must offer optimal visual conditions for both athletes and spectators. Broadcasting presents further demands on the lighting. For excellent visual conditions, adequate vertical components and a good localised uniformity of horizontal components are vital. At the same time it is important to determine that glare effects from floodlighting are kept to a minimum.
Projectors with symmetrical distribution as well as floodlights with symmetrical/asymmetrical distribution with metal-halide lamps are favoured. These are mounted on masts, whereby 4-mast constructions with spotlights satisfy the basic requirements for quality with regard to athletes, spectators and television. This is especially the case with stadiums holding large crowds, with large visual distances between spectators and athletes. Trunking systems on grandstand roofs with floodlights for symmetric and asymmetric distribution offer a good alternative to a 4-mast construction, or can serve to complete such a construction.
