About Interferenz

Interferenz Lichtsysteme GmbH was founded in 1972 by Alfred Korsch and has since been manufacturing project and custom luminaires for architectural applications at its site in Tönisvorst. The company specialises in the development and production of custom LED luminaires, including downlights, spotlights, wall lights, pendant luminaires, LED tubes and custom-made solutions for projects. Customer-specific lighting solutions are developed in the company's own lighting laboratory; historic luminaires are also retrofitted to LED technology. In addition to artificial lighting, the sister company Interferenz Daylight GmbH plans and distributes standardised daylight systems such as Solatube light tubes and heliostats. Aluminium (including anodised high-purity aluminium 99.96% for reflectors) as well as polycarbonate, acrylic glass and plastic are processed for housings and optics at the factory. Customers come from industries such as automotive, banking, telecommunications, retail, hotels, churches, insurance and Deutsche Bahn.
