Problem

Atlanta airport illuminates their aircraft parking apron with over 740 high pressure sodium lights during night-time operations. High illuminance levels are necessary to provide adequate safety for ground personnel working through the night. The lighting is controlled via mechanical timers which occasionally fail and leave many lights burning, wasting energy during the day. The HPS lights require constant maintenance with frequent replacement cycles.

Solution

Retrofit legacy HPS lights with BLS NOVA HM LED High Mast fixtures. NOVA HM LED fixtures consume only 570 watts and offer flexible optical packages for optimal light coverage on the apron. The crisp, brilliant white light delivers an average illuminance over 4 foot-candles and offers improved color recognition for security cameras and better night-time visibility for ground personnel. Integrated BLMS controls achieves up to 30% in additional energy savings. Adjustable glare shields eliminate light trespass for pilots and ground crews. A 100,000 hour L80 lifetime reduces maintenance costs by $22,910 annually.
