In a gymnasium used for sports lessons, club training and competitions, a degree of illuminance of 500 lx is required on the playing field. The playing field is lined with stands. To be able to see well, a degree of illuminance of 50 to 100 lx is required in these areas. At least 10 lx is required for emergency lighting. The entire illumination of the 2100 square metre large hall is effected using ballproof high-performance floodlights with a colour temperature of 4000 K. Aisles and stairs are equipped with shielded recessed luminaires. This ensures that neither the sportspersons nor the spectators are dazzled.
