LEDVANCE developed a sustainable and customized lighting concept for Bayer 04 Leverkusen in both indoor and outdoor areas. As part of this, the Ulrich-Haberland Stadium underwent modernization, with the four existing floodlight poles being replaced by modern arena floodlights. Additional floodlights were installed, including some on a specially constructed 30-meter high mast, to ensure optimal light distribution and an illuminance level of 800 lux.
