Code Beacon Lamps, 125-130V 620W Heavy Duty, FAA L-864, 6Pack

DURO MEX Code Beacon Lamps deliver dependable, high-visibility illumination for aviation obstruction warning systems, communication towers, air traffic hazard marking. Designed for critical beacon systems, these heavy-duty lamps provide reliable performance in environments where clear warning signals are essential. Built with high-strength heat-resistant glass, each lamp is engineered to resist wind vibration and severe thermal shock in challenging outdoor conditions. Heavy-duty resilient filaments support extended operating life and help reduce replacement frequency in elevated or hard-to-access installations. The reinforced internal construction supports the filament at seven points, helping maintain precise filament position, consistent light projection, and resistance to vibration-related failure. A mica reflector disc helps direct heat away from the bulb base, supporting stable operation and reducing thermal stress near the electrical contact area. Each lamp is equipped with a brass prefocus base and precision eyelet for secure electrical contact and accurate filament alignment. Designed for FAA L-864 Incandesceent Type beacon warning systems, DURO MEX Code Beacon Lamps provide rugged, dependable performance for aviation, tower, and industrial warning applications.
