The TKH Inset Runway Centerline Light Type RCL is a high-performance, long-lasting lighting solution engineered for precision and safety in modern airfield ground lighting systems. Designed to meet the demanding requirements of international aviation standards, this fixture offers superior optical performance, rugged construction, and intelligent functionality for use on commercial and military runways.
With a compact outer diameter of 8 inches and a low-profile height of just 6.35 mm above the pavement surface, the RCL light ensures minimal disruption to aircraft operations while maintaining durability and structural integrity. The unit’s depth below flange measures 35 mm, and the light outlet—sized at 40 mm by 6 mm—delivers highly controlled light output suitable for runway centerline applications. Built to withstand the harshest environmental conditions, the fixture is rated IP68 for dust and water ingress, enabling long-term reliability in exposed outdoor environments.
The RCL light is powered by advanced LED technology, offering a useful lamp life of up to 50,000 hours and an overall lifetime exceeding 20 years. It operates at a nominal current of 6.6 A with precise dimming from 0 to 100 percent. Power consumption is highly efficient, drawing just 19 watts per side for white output and 15 watts for red. The fixture maintains a power factor greater than 95% at nominal current, ensuring excellent energy performance. Voltage ranges from a minimum of 1.7 V at 0.1% output to a maximum of 5.8 V at full power. The chromaticity coordinates comply with ICAO Annex 14, Volume 1 and FAA AC 150/5345-46E standards, ensuring visibility and color consistency for safe aircraft guidance.
Engineered for resilience, the light operates in extreme ambient temperatures ranging from -55°C to +85°C (-67°F to +185°F), making it ideal for deployment in a wide range of global climates. An internal serial interface is included for diagnostics and parameterization, facilitating system monitoring and maintenance. Optional features further enhance the fixture's adaptability: a fail/open function for fault detection, a de-icing kit requiring a minimum of 14 watts during operation for snow and ice prevention, and a sapphire-coated prism for increased abrasion resistance and optical clarity.
The RCL light is also compatible with CEDD® technology—a smart, safe, and sustainable airfield ground lighting system developed by TKH. CEDD® integrates power and data transmission into a single cable via induction, allowing airfield lights to be installed, replaced, or upgraded quickly and safely without the need for direct electrical contact. With optional integrated single-lamp control using CEDD®, the RCL offers intelligent lighting management, significantly reducing maintenance time and increasing operational efficiency in airfield environments.
In summary, the TKH RCL Inset Runway Centerline Light combines robust construction, high-efficiency LED optics, intelligent control capabilities, and compliance with international aviation standards to deliver a best-in-class solution for critical runway centerline marking and guidance.
