A study was conducted to determine the viability of an LED-based parking garage light. The requirements for this light were based on the Illumination Engineering Society of North America (IESNA) enclosed parking/driving lanes specifications. Three basic optical designs were compared. The first used no secondary optic, the second used a reflector optic, and the third used a lens optic. Based on the findings herein, the IESNA requirements could be met using approximately 121 1-watt LEDs of typical performance today. Compared to metal halide, high pressure sodium, and fluorescent lights the LED fixture would have a longer lifetime as well as equal or better color rendering index and energy efficiency. Although the energy consumption and the re-lamping frequency could be significantly less for an LED fixture, currently the initial cost of a fixture meeting the IESNA requirements would be more than several times higher than that of existing fixtures. LED cost per lumen is decreasing rapidly, however, it will likely take several years before a cost effective LED light can provide the same performance as metal halide, high pressure sodium, and fluorescent lighting in parking garage applications.
