Issues with Use of Airfield LED Light Fixtures. Airport Cooperative Research Program (ACRP) Synthesis 35. A Synthesis of Airport Practice

J. D. Bullough

Light-emitting diode (LED) airfield lighting is increasingly used at airports in the United States and abroad. The objective of this synthesis study is to provide documentation about the performance of LED airfield lighting systems, and it is primarily intended for airfield operations managers and airport electrical maintenance staff. Information about LED lighting systems in terms of performance, cost, and other operations issues is not readily found in a single location. This report is an effort to gather information about airport experiences and feedback with LED airfield lighting. A literature review and a survey of individuals representing airports that have experience with LED airfield lighting were conducted. Individuals from 22 airports and aviation agencies agreed to participate in the survey and all 22 completed it (for a 100% response rate). In general, the study findings confirm that LED airfield light fixtures reduce energy use and maintenance requirements, compared with conventional airfield lighting technologies. LED airfield lighting systems have been in use for a number of years, and most feedback on their visibility and performance is positive. Early compatibility issues appear to have been largely overcome through technological progress and through efforts of the FAA to address LED technologies in its guidance to airports.
