LERE LED Elevated Runway Edge and Threshold/End Light

The LERE is an elevated LED fixture covering the two most numerous elevated-light positions on a runway: edge lights (white in the landing direction, yellow in the last 600 m) and threshold/end lights (green threshold-facing, red runway-end-facing). Whereas inset fixtures require pavement cutting and can installation, the LERE is surface-mounted on a frangible base, making it the primary choice for runways where pavement excavation is not available or approved — including overlaid runways, thin-slab pavements, and military runways with rapid-repair requirements.

The 175 mm diameter head is compact relative to the fixture's photometric output. At 29.2 VA without heating — a figure consistent across both ICAO and FAA L-861 intensity requirements — the LERE imposes substantially lower electrical load than the halogen L-861 units it replaces, which typically drew 45–65 W per fixture. On a runway with 150 edge lights, that differential represents a meaningful CCR load reduction.

Height options — 320 mm (ICAO) and 14 inches/355 mm (FAA) — are the standard frangible mounting heights prescribed by ICAO Annex 14 Appendix 2 and FAA AC 150/5345-46 respectively, ensuring obstacle-limitation surface compliance without custom engineering.

Built-in electronics resist shock and vibration from jet blast and propeller wash. Automatic fault detection with alert output feeds directly into ALCMS platforms, enabling fault-driven maintenance dispatch rather than scheduled inspection rounds. Documentation is available in six languages, reflecting OCEM's global deployment footprint.
