Beutelsbacher Halle in Weinstadt is a popular venue that hosts a wide array of sport and recreational activities and fits up to 1,000 people when used as a festival hall. A sleek, functional LED solution that could be used both as is and as a pendant luminaire mounted to the ceiling was needed to light the multi-functional hall. The ball-resistant luminaire ROBUST met these mechanical and technical requirements. These sleek luminaires look great on the slat ceiling of the 45 m long hall, and constitute an optimal and efficient lighting solution.
