The PRO APF 12/8" L-852 TCL is an LED taxiway centerline light designed primarily to assist ground traffic during periods of low visibility by guiding aircraft safely between the runway and parking areas. Available in an 8-inch size, with or without a support ring, the TCL fixture typically emits a yellow or green bidirectional light, providing clear directional cues for pilots navigating taxiways.
This lighting system is fully certified and compliant with key aviation standards, including FAA AC 150/5345-46 (current edition), FAA Engineering Brief 67, and NATO STANAG 3316. It is also ETL certified, ensuring that it meets rigorous safety and performance benchmarks.
The PRO APF 12/8" L-852 TCL incorporates Wavetrac™ technology, significantly reducing power consumption by up to 60% compared to incandescent alternatives. Its advanced LED modules deliver a rated projected life exceeding 50,000 hours at 6.6 A, promoting long-term reliability and minimizing maintenance demands. The fixture's design is dust- and watertight, rated at IP68, providing superior protection against environmental elements.
Maintenance is streamlined thanks to its modular construction, which reduces the number of parts to stock and simplifies servicing. The fixture complies with FAA Engineering Brief 67 for dimming curves and Engineering Brief 83A for secure fixture attachment to support rings. High-frequency 400 Hz pulse-width modulation (PWM) technology minimizes flicker perception, enhancing pilot comfort and safety.
Compatible with all known Constant Current Regulator (CCR) types, including Thyristor (Series) CCRs across 6 or 8 steps, the fixture also features a 3.5 crest factor to ensure smooth operation within various control systems. Built-in surge protection rated at 10kV/5kA safeguards the light against electrical disturbances.
The PRO APF 12/8" L-852 TCL is engineered to perform reliably in extreme temperatures ranging from -40°C to +85°C, making it suitable for use in the most challenging environments. Additional safety features include built-in failure monitoring to ensure fixture integrity. Its low-profile housing conforms to IEC Style 3 standards, with a protrusion of only 6 to 13 mm, and the fixture maintains a maximum profile height of less than 0.25 inches (6.35 mm), consistent with FAA Style 3 guidelines.
Together, these features make the PRO APF 12/8" L-852 TCL an efficient, durable, and reliable solution for taxiway centerline lighting in airports worldwide, ensuring safe aircraft movement under varying weather and visibility conditions.
