The RELIANCE Taxiway Edge L-852T(L) is a low-protrusion 8-inch omnidirectional LED inset light fixture engineered to meet the rigorous demands of modern airfield operations. Designed to replace traditional incandescent lighting systems, this advanced fixture significantly reduces maintenance requirements and operational downtime while improving energy efficiency and overall sustainability. Featuring blue or yellow LEDs, the RELIANCE L-852T(L) is suitable for a range of applications including taxiway edge lighting in compliance with FAA L-852T(L), intermediate holding positions per Australia’s MOS 139, and constant-intensity edge lighting for turnpads.
Built on state-of-the-art LED technology, the RELIANCE fixture delivers a long-lasting and environmentally friendly lighting solution. The use of LEDs not only minimizes power consumption but also offers robust resistance to vibration and environmental stress. Precision-engineered optics optimize photometric performance and extend LED life, while a reduced bottom pan profile supports installation in very shallow base cans. The fixture's LED output is modulated at 400 Hz using pulse-width modulation (PWM), ensuring consistent visual performance without flicker across all brightness levels, even for moving observers. It also features full dimming capabilities, following the traditional halogen dimming curve, and operates reliably with all steps of FAA- and IEC-compliant constant current regulator systems.
The RELIANCE L-852T(L) supports a broad range of international aviation standards, including FAA L-852T(L), ICAO Annex 14 Volume 1, IEC 61827, EASA CS-ADR-DSN, Canada TP 312, and Australia MOS 139, making it an ideal global solution. Its construction reflects a strong commitment to sustainability and resilience. An IP68-rated enclosure ensures protection in harsh outdoor environments, while stainless steel fasteners resist corrosion. A reinforced top cover enhances mechanical durability, and an optional reinforced prism is available for demanding applications. Furthermore, its universal all-in-one power supply is compatible across the runway, taxiway, approach, and omni inset lighting families, enabling streamlined inventory and replacement processes.
Safety and system compatibility are also prioritized in this fixture. It includes built-in lightning protection in accordance with ANSI/IEEE C62.41-1991, rated to withstand Category C2 surges (10,000 V, 5,000 A). The fixture is available with a fail-open circuit option to maintain compatibility with legacy monitoring systems and also supports advanced control and monitoring technologies through integrated Fail-LED detection, as outlined in FAA Engineering Brief 67D. For enhanced digital infrastructure, the EQ variant incorporates an ILCMS remote module using OFDM technology, enabling seamless integration with ADB SAFEGATE’s LINC 360 system for robust communication and data capacity.
Power supply options include non-monitored versions for simple installations, monitored versions featuring fail-open circuitry, and advanced EQ models with integrated digital control. This range of configurations ensures that the RELIANCE Taxiway Edge L-852T(L) fixture can be precisely tailored to meet the specific needs of airports worldwide, from conventional taxiway operations to smart airfield lighting networks.
