Osram lamp Nav 21W E27 Led Filament

Osram NAV 50 LED Filament is a 21W E27 tubular LED lamp manufactured by Osram, engineered as a direct replacement for traditional high-pressure sodium (NAV) lamps. The transparent tubular glass body, measuring Ø38 × 170 mm, faithfully replicates the appearance of conventional NAV lamps and ensures full compatibility with existing reflectors thanks to its 360-degree beam angle.

With an efficiency of up to 190 lm/W, this lamp delivers energy savings of up to 78% compared to the sodium vapour lamps it replaces. It is available in two colour temperatures: the 2700K very warm white version provides a luminous flux of 3600 lm, while the 4000K neutral white version reaches 4000 lm. Light output is instant at 100% with no warm-up delay. With a rated lifespan of 25,000 hours, a power factor of 0.9, an IP65 protection rating and surge protection up to 2 kV, the lamp is well suited for roads, pedestrian areas, parks and large outdoor surfaces when installed in suitable luminaires. It operates with a conventional ballast (CCG) or 230 V AC mains; it is not dimmable and is not compatible with igniters. The 21W power consumption is equivalent to a 50W halogen lamp.
