In 2020, a major sports stadium in Thailand upgraded its system to improve the quality of lighting by adopting 1000W circular FI Series stadium floodlights. The floodlights were set at a height of 18 meters for optimal illumination, ensuring that every corner of the stadium received an even and bright light, and successfully eliminating strong direct light and shadows. The upgrade not only provides an unprecedented visual experience for spectators and TV broadcasts, but also makes the new system more energy efficient than traditional lighting methods. The project owner expressed deep satisfaction with the results of the lighting upgrade project.
