The retractable roof on Wimbledon's Centre Court presented unique lighting challenges due to its very low height. To minimize glare for players and spectators, the lighting design team implemented indirect lighting by reflecting some light off the roof itself to create diffuse lighting across the court. Lutron's GRAFIK 7000 lighting control system was installed to provide precise, automated control of the lighting zones and meet the BBC's requirements for high-definition coverage. Testing confirmed the innovative lighting design passed requirements and was praised for its technical sophistication.
