The TKH Inset Rapid Exit Taxiway Light Type RETL800 is a high-performance, low-profile airfield lighting fixture designed specifically for rapid exit taxiways at commercial and military airports. Engineered for long-term durability and maximum safety, the RETL800 has an 8-inch outer diameter and maintains a low 6.35 mm profile above the pavement surface. Its minimal depth below the flange, only 35 mm, ensures straightforward installation even in shallow base cans. The light outlet, measuring 40 mm by 6 mm, delivers precise illumination that conforms to rigorous international aviation standards.
Constructed for extreme conditions, the RETL800 is rated IP68 for complete protection against dust and prolonged water submersion, making it suitable for continuous outdoor use in all climates. The fixture operates reliably in ambient temperatures ranging from -55°C to +85°C (-67°F to +185°F), and its robust design ensures an overall lifetime exceeding 20 years. The integrated LED light source offers up to 50,000 hours of useful lamp life, contributing to a lower total cost of ownership through reduced maintenance and energy consumption.
The RETL800 is fully compliant with ICAO Annex 14, Volume 1, and FAA AC 150/5345-46E chromaticity requirements. It supports a nominal current of 6.6 A with a power factor greater than 95% at that level, ensuring efficient energy usage. The power consumption is optimized at 21 W for yellow and 23 W for green LEDs when operating at full current (6.6 A). The light’s electrical characteristics include a maximum voltage (Umax) of 3.5 V and a minimum operating voltage (Umin) of 1.7 V at 0.1% output.
Designed for smart ground lighting systems, the RETL800 features an internal serial interface that enables diagnostics and parameterization, enhancing operational transparency and control. Optional features include a fail/open circuit function for added safety, a sapphire-coated prism for improved optical performance and scratch resistance, and a de-icing kit, which adds a minimum of 14 W of power draw during operation to ensure continued performance in cold and icy environments.
Furthermore, the RETL800 is compatible with CEDD® technology, a cutting-edge inductive power and data solution developed for smart, safe, and sustainable airfield lighting systems. With CEDD®, energy and data are transmitted through a single cable without direct electrical contact. This innovation allows lights to be installed, maintained, or replaced easily and safely, significantly reducing system downtime and complexity.
Overall, the TKH RETL800 is a future-ready, energy-efficient solution tailored for the demanding conditions of rapid exit taxiways, offering exceptional reliability, minimal maintenance, and advanced integration capabilities for modern airfields.
