The Norman Lamps 052542 is a 150W tungsten halogen airfield runway lamp designed to replace the ANSI EWR standard bulb used in FAA airport lighting systems. Operating on a 6.6A series current circuit at 22.7V, this halogen lamp delivers 3750 lumens of bright, consistent illumination essential for pilot visibility during approach, taxi, and landing operations.

Built with a tubular T4 clear quartz envelope and a CC-6 oval filament, this halogen bulb provides precise light center alignment for use with prismatic and reflector-based runway fixtures. It is commonly specified for FAA Airport Runway Lighting Designations L-852E/F, L-861SE, L-862, and L-862E, including in-pavement taxiway intersections, medium intensity elevated runway threshold end lights, high intensity elevated edge lights, and runway threshold end lights.

The GZ9.5 two-pin prefocus ceramic base ensures secure, vibration-resistant mounting and repeatable filament positioning inside airfield fixtures. Rated for 1000 average life hours and fully dimmable across the constant-current regulator range, this halogen airfield lamp is a direct replacement for EWR-coded bulbs from major manufacturers used throughout commercial, military, and heliport airfield lighting installations.
