The most suitable lighting for swimming baths consists of compact reflector luminaires or floodlights with metal halide lamps. They are mainly directly inclined and for easy maintenance are mounted outside of the water area.
Secondary reflector systems are also particularly suitable for the lighting of swimming baths.
The maintenance-free reflector system is positioned above the water surface. The respective projectors are to be found in an easily accessible area. The luminaires must be well protected against moisture, and for this reason only luminaires protected to IP54 and higher are deployed.
Indirect lighting for swimming baths with fluorescent lamps or metal halide lamps has the disadvantage of causing considerable reflection on the water surface, thereby hampering the ability to see through it. Additional underwater projector lighting reduces this effect.
