The floodlight system of the Dalian Barracuda Bay Football Stadium project, China’s first professional football stadium surrounded by sea on three sides, is launched, lighting up a new landmark of the city. The stadium is currently the world’s largest professional football stadium in terms of membrane structure coverage and the number of single-layer ETFE membrane structures used. The floodlight system takes marine-blue and cloud-white as the main colors: the facade takes blue sea as the theme and the ceiling lighting looks like white clouds, highlighting the romantic seaside hues.
