The PRO APF 12/8" L-850 RCL/TDZ LED light serves as an 8-inch inset fixture designed for use as either a runway centerline light or a touchdown zone light, with options available both with and without a support ring. The L-850 RCL model is a bidirectional light, typically configured in white/white or white/red, providing clear runway centerline guidance to pilots during approach and landing. In contrast, the L-850 TDZ variant functions as a unidirectional white light, marking the touchdown zone to aid pilots in precise and safe landings.
This fixture meets rigorous aviation standards and certifications, including the FAA AC 150/5345-46 current edition, FAA Engineering Brief 67, FAA Engineering Brief 83A, and NATO STANAG 3316, ensuring compliance with both civil and military airfield lighting requirements. The light is ETL certified, confirming its safety, quality, and performance under stringent industry benchmarks.
Incorporating advanced Wavetrac™ technology, the PRO APF 12/8" L-850 RCL/TDZ significantly reduces power consumption by up to 60% compared to traditional incandescent fixtures. Its LED technology boasts a long projected life exceeding 50,000 hours at 6.6 amps, making it a highly reliable and cost-effective lighting solution. The fixture is fully dust- and watertight, rated to IP68 standards, providing robust protection against harsh environmental conditions.
The modular design of the fixture simplifies maintenance, reducing the number of parts that must be stocked and enabling faster servicing when necessary. It features dimming compatibility with the FAA Engineering Brief 67 current edition, and secure fixture attachment compliance per Engineering Brief 83A. The use of high-frequency 400 Hz pulse-width modulation (PWM) minimizes flicker perception, enhancing pilot comfort and safety during nighttime or low-visibility operations.
This LED runway light is compatible with all known Constant Current Regulator (CCR) types, including Thyristor (Series) CCRs, across 6 or 8 steps. Its 3.5 crest factor further ensures seamless operation within series CCR systems. Additional electrical protections include built-in surge suppression rated at 10kV/5kA to safeguard against voltage spikes.
Engineered for performance in extreme conditions, the fixture operates reliably across a wide temperature range from -40°C to +85°C, ensuring safe aircraft movement in the most challenging climates. It features an IEC Style 3 low-profile housing with a protrusion of 6 to 13 mm and conforms to FAA Style 3 standards, maintaining a profile height of less than 0.25 inches (6.35 mm). For colder environments, an optional patent-pending arctic kit is available to maintain performance and durability.
Overall, the PRO APF 12/8" L-850 RCL/TDZ offers a robust, energy-efficient, and easy-to-maintain lighting solution suitable for modern runways, supporting both civil and military aviation with superior visibility, reliability, and compliance.
