Old lighting was replaced by 78 LED luminaires with 80 W, 120 W and 200 W input power. Implementing LED replacement resulted in a 45% reduction in annual energy use costs. Additional 30% savings (total energy saving is about 75%) is delivered by SEAK lighting control, which automatically adjusts the lighting intensity to ideal values. Both safety and economy has been improved.
