The RELIANCE Elevated Runway Guard Light is a high-performance unidirectional airfield lighting fixture designed to deliver enhanced visibility and compliance in critical runway environments. Emitting alternating yellow LED flashes, this fixture serves as a runway guard light in accordance with ICAO standards (§5.3.23), ensuring clear visual cues for pilots at runway/taxiway intersections. It is engineered to meet the stringent requirements of ICAO Annex 14 Volume 1 (Current Edition), IEC 61827, and EASA CE-ADR-DSN, offering global regulatory compliance and suitability for international airports.
The fixture utilizes long-lasting LED technology, providing energy efficiency and a highly visible light output without visual flicker. With fully encapsulated all-in-one electronics, the RELIANCE Guard Light features integrated voltage surge and lightning protection for safe and uninterrupted operation. A standout feature is its availability with RELIANCE IQ – an integrated intelligent lighting control and monitoring system (ILCMS) that enables remote control and diagnostics. Additionally, the fixture can be equipped with RELIANCE’s fail-open (Mon) technology to ensure safety-critical redundancy in case of failure.
The mechanical design emphasizes durability and operational reliability. It includes an IP68-rated, anodized and powder-coated aluminum housing with all fasteners made of stainless steel, optimized for harsh weather environments. The modular construction and minimal mechanical components allow for easy handling and streamlined maintenance. The unit is operational on 3- or 5-step ferroresonant or thyristor constant current regulators (CCRs) that comply with both FAA and IEC requirements, making it compatible with existing airfield infrastructure worldwide.
In terms of electrical performance, the RELIANCE Elevated Runway Guard Light integrates a robust encapsulated 6.6 A electronic converter with a two-pole L-823 plug for transformer connection. It achieves a power factor typically greater than 0.9 at 6.6 A, ensuring efficient energy use. The fixture operates reliably in extreme environmental conditions, with an operating temperature range from -55 °C to +55 °C (-67 °F to +131 °F) and a storage temperature range extending up to +75 °C (+167 °F), while withstanding humidity levels up to 100%.
This elevated guard light exemplifies next-generation airfield safety and reliability, combining rugged design, cutting-edge LED performance, and intelligent control capabilities for modern aviation infrastructure.
