The PRO APF ICAO High Intensity Runway Edge Light (HIRL) is an advanced LED lighting fixture designed to serve as a high intensity runway edge light, high intensity threshold/end light, and displaced threshold light. This fixture is engineered to provide maintenance-free operation, delivering both a long lifespan and high lumen output to meet the demanding requirements of airfields worldwide. The PRO APF HIRL is available in multiple models specifically designed to comply with major international standards, including those set by the FAA, ICAO, and TP-312.
Certifications and compliances for the PRO APF ICAO HIRL reflect its global applicability and adherence to rigorous aviation safety standards. These include ICAO Aerodromes Annex 14, Volume 1 (Sixth Edition, July 2013), IEC TS 61827 (First Edition, May 2004), ICAO Aerodrome Part 6 Frangibility (First Edition, 2006), and NATO STANAG 3316. These certifications ensure the fixture meets critical criteria for safety, reliability, and performance in airport environments worldwide.
The design of the PRO APF ICAO HIRL incorporates WaveTrac™ technology, which significantly reduces power consumption by up to 60% compared to traditional incandescent lighting. This technology enhances energy efficiency while maintaining superior light output. The fixture provides a full 360-degree viewing angle with an omnidirectional halo, ensuring maximum visibility for pilots during low-visibility conditions.
Ease of installation and maintenance is a key feature of this design. The glass dome is secured to the housing with a removable flange ring, allowing quick access to the power supply and LED optical assembly for fast servicing. Leveling is facilitated by three hex head bolts, making precise adjustments simple and reliable. The fixture is available in installed heights of 14 inches (350mm), 24 inches (607mm), and 30 inches (759mm), and is compatible with both 1.5-inch and 2-inch baseplate hubs for versatile installation options.
The PRO APF ICAO HIRL uses long-life LED technology, rated to exceed L70 at 50,000 hours at 6.6 amperes, ensuring durability and consistent performance over many years. Its housing is constructed from highly durable cast aluminum, providing robust protection against harsh environmental conditions. To eliminate flicker perception, the fixture utilizes a high-frequency 400 Hz pulse width modulation (PWM) system, delivering smooth and stable light output.
Additional protective features include 10kV/5kA surge protection to safeguard the fixture’s electronics against electrical spikes. For cold weather applications, an energy-efficient arctic kit is available, which employs a filament applied directly to the glass dome to minimize energy losses and prevent icing. The fixture also features a frangible coupling with an integral fluid barrier, effectively preventing ambient moisture or precipitation from entering the base assembly.
All LED components and electronics are housed within an IP67-rated enclosure, ensuring dust and water tightness for reliable operation in challenging airport environments. Overall, the PRO APF ICAO HIRL combines advanced technology, global compliance, and rugged construction to deliver a high-performance runway lighting solution trusted by airports worldwide.
