70W high-pressure sodium tubular lamp with an E27 Edison Screw base. Producing approximately 6,000 lumens of amber 2000K illumination, this OSRAM VIALOX® NAV SON-I HID lamp is ideal for security lighting, roadways, industrial sites, warehouses, agricultural buildings, and municipal infrastructure.
What it is
The OSRAM VIALOX® NAV SON-I 70W E27 Tubular High-Pressure Sodium Lamp is a professional-grade high-intensity discharge (HID) lamp engineered to provide efficient, dependable illumination for commercial, municipal, industrial, and agricultural applications.
Its clear tubular outer bulb maximises light transmission and reflector efficiency, while the E27 Edison Screw (ES) base provides secure installation in compatible HID luminaires. Producing approximately 6,000 lumens of characteristic amber 2000K illumination, this lamp offers excellent efficiency, long service life, and dependable performance for outdoor and area lighting applications.
Unlike conventional household lamps, this HPS lamp requires compatible 70W HID control gear, including a ballast and ignitor, for safe and correct operation.
