LED technology has evolved into many “white light” applications, including parking lot lighting. As this technology has advanced, testing suggests that benefits include high-quality lighting and long life. The lifetime cost of LED luminaires can be less than the alternative HID or HPS lighting due to their low power consumption and long life, which correlates to some of the benefits for LED lighting in parking lots. LED is becoming more common in street light applications because it projects the lumen output of the LED more efficiently, which allows for wider coverage of a consistent light pattern. Uniformity is one of the benefits of a well-designed solid state lighting product and project. Therefore, the same considerations can be applied to open air parking lots.
