We illuminated the football field and the tennis court with FL13 HiFlex lights. We used 20 pcs of 200W HiFlex and 28 pcs of 400W HiFlex, all with a color temperature of 5000K and a color rendering index of 70. The HiFlex lights had adjustable brackets that allowed us to control the light direction precisely. This maximized the lighting efficiency and minimized the light waste. The HiFlex lights brightened both the football field and the tennis court at night, creating a pleasant environment for the players to enjoy the games.
