The existing swimming pool lighting had to be replaced by LED lighting. The whole pool should be illuminated down to the bottom to increase the safety of the swimmers without blinding them. The external conditions with very humid air and high chlorine content were another challenge. The DeltaLUXX is ideally suited for this owing to its standard Teflon coating and IP65 protection category. The luminaires were mounted in the technical equipment room behind the concrete wall using a custom-made assembly bracket.
