The LEDVANCE LED replacement for NAV lamps in design-oriented outdoor applications offers several benefits, including maintaining the same design as traditional NAV lamps with a frosted, ellipsoid full glass bulb for aesthetic continuity. Its 360-degree beam angle ensures full utilization of the existing luminaire's reflector. With energy savings of up to 78% compared to sodium vapour lamps (NAV) and instant 100% light output without warm-up time, it provides efficient and immediate illumination. Additionally, it offers similar light distribution to traditional NAV lamps. Suitable for various outdoor settings such as streets, area lighting, pedestrian zones, and parks, it enhances both design and functionality. However, it should only be used in luminaires suitable for outdoor applications to ensure optimal performance.
Suitable for operation with conventional control gear (CCG) or 230 V AC mains
