The IREL-L Style 2 LED Runway Edge Lights have an average LED life of 56,000 hours under high-intensity conditions and more than 150,000 hours under typical operating conditions, which significantly reduces ongoing maintenance costs and virtually eliminates runway shutdowns due to relamping. The IREL-L is used in runway edge applications on Category I, II, and III runways. It is also used in military runway edge applications that are 60 m (200 feet) wide or more.
