Ontario International Airport covers 1,741 acres with 12 passenger airlines flying to and from 17 domestic and 2 international destinations. It served over 4.5 million passengers in 2017 and 2.4 million passengers in first half of 2018. The airport has 2 terminals and 4 adjacent parking lots. The parking lots are originally equipped with 400W HPS as the primary lighting source. SolarMax LED converted the exterior pole lights for parking lot #2 and #4 and installed 313 LED luminaires to cover the parking space and roadway. The parking lot pole LED area luminaires contain embedded PIR occupancy dimming sensors that further reduce the energy consumption by additional 50% when the lot is vacant and immediately resume to full brightness when motion is detected.
