ST11 HiPole X lit up an outdoor tennis court in the UK. Due to the low efficiency and high energy consumption, previous lighting fixtures were retrofitted to our HiPole X. With HiPole X, the tennis court was fully illuminated with sufficient and uniform lighting. Thus, players were able to enjoy the sport both day and night, while the operator could save more energy costs. Apart from higher lighting performance and lower operating costs, HiPole X also contributed to easier installation.
