The TKH Inset Taxiway CenterLine Lights, available in Type TCL and TCC variants, are advanced LED airfield lighting solutions engineered to deliver exceptional performance, reliability, and compliance with international aviation standards. These lights feature an 8-inch outer diameter and a low-profile height of just 6.35 mm above the pavement surface, ensuring minimal disruption to aircraft taxiing. The installation depth below the flange is 35 mm, while the light outlet measures 40 mm by 6 mm, providing focused illumination that meets strict operational requirements.
Designed for durability and resilience, these fixtures are fully sealed against dust and water ingress, boasting an IP68 protection rating for long-term functionality in harsh airfield environments. With an overall expected service life of over 20 years and LED lamp life reaching up to 50,000 hours, the TKH inset lights offer long-lasting performance and reduced maintenance requirements. The lights comply with chromaticity standards set forth by ICAO Annex 14, Volume 1, and FAA AC 150/5345-46E, ensuring accurate and consistent light color for taxiway centerline applications.
Operating at a nominal current of 6.6 A, these lights demonstrate excellent energy efficiency. Power consumption varies based on configuration: 12 watts per side for green straight, 9 watts for green curved, 11 watts for yellow straight, and 9 watts for yellow curved lights. The voltage ranges from a minimum of 1.0 V at 0.1% output to a maximum of 1.8 V at full output, and the system maintains a power factor greater than 95% at nominal current levels. These specifications ensure stable operation even under fluctuating airfield power conditions.
The lights are engineered to withstand extreme ambient temperatures ranging from -55°C (-67°F) to +85°C (+185°F), making them suitable for deployment in diverse climates. An internal serial interface allows for diagnostics and parameterization, supporting advanced monitoring and configuration capabilities. Optional features include a fail-open function to maintain system integrity during faults, a de-icing kit which adds a minimum of 14 watts during operation for cold-weather functionality, and a sapphire-coated prism for enhanced optical durability.
Additionally, these inset lights are compatible with CEDD® technology—an innovative, contactless system that delivers both energy and data through a single cable using induction. This allows for safe, tool-free installation and replacement without the need for traditional electrical connections. When combined with CEDD®, the lights also support integrated single-lamp control, enabling smart, efficient airfield lighting management that aligns with modern airport infrastructure needs.
