The PRO APF 8" ICAO TCLI is a high-performance LED taxiway centerline light designed to provide reliable ground traffic guidance under low-visibility conditions, such as fog, heavy rain, or nighttime operations. Commonly deployed along taxiways between runways and parking stands, this fixture enhances pilot awareness and aircraft safety. The TCLI (Taxiway Centerline Light) typically emits a yellow or green bidirectional beam and complies with stringent global aviation standards, making it suitable for both civil and military airfields worldwide.
This advanced fixture meets the specifications set forth by ICAO Annex 14 Volume 1 and Part 4, NATO STANAG 3316, FAA AC 150/5345-46 (current edition), and EB67 (current edition), ensuring wide interoperability and regulatory compliance. Engineered with Wavetrac™ technology, the PRO APF significantly reduces power consumption—by up to 60% compared to traditional incandescent fixtures—while delivering high optical performance.
At the core of the design is long-life LED technology rated for over 50,000 operating hours at 6.6A. The unit is sealed to IP68 standards for dust and water resistance and built with a modular architecture that simplifies maintenance and reduces parts inventory. The fixture features Engineering Brief 67-compliant dimming curves and operates across 6 or 8 intensity steps for ICAO applications. Its high-frequency 400 Hz PWM (Pulse Width Modulation) control helps eliminate visible flicker, and it is compatible with all known CCR types, including thyristor-based (series) CCRs. A 3.5 crest factor ensures stable performance on series circuits.
Further enhancing reliability and safety, the PRO APF TCLI includes integrated failure monitoring, robust 10kV/5kA surge protection, and a broad operating temperature range from -40°C to +85°C. These capabilities make it well-suited for extreme climates, including arctic regions, with an optional arctic kit available for additional thermal protection. The light’s IEC Style 3 housing is low-profile (less than 0.25 inches or 6.35 mm), minimizing surface protrusion and supporting FAA Style 3 requirements for aircraft movement areas.
