OSRAM NAV-E 350W E40 Sodium Vapor Lamp

The OSRAM NAV-E 350W E40 sodium discharge lamp is a professional light source designed for industrial, street lighting, and large-space applications. With a luminous flux of 34,000 lumens and a luminous efficacy of 97 lm/W, it delivers high performance in settings where light output is a priority.

High-Efficiency Street and Road Lighting

This discharge lamp is the ideal choice for street lighting systems, parking lots, and public areas. The 2,000K color temperature produces a very warm white light—characteristic of sodium—which enhances nighttime visibility and reduces glare. The E40 base allows for quick integration into existing fixtures, minimizing installation time in retrofit projects or new installations.

Industrial and High-Volume Applications

For warehouses, manufacturing facilities, and storage areas, the NAV-E sodium lamp offers a balance between energy consumption and light output. The average lifespan of 20,000 hours reduces the frequency of maintenance, lowering operating costs in facilities with extended operating hours. The lack of dimmability makes it suitable for environments where stable, continuous lighting is required.

Design Features and Reliability

The ellipsoidal design of the sodium discharge lamp, with a diameter of 122 mm and a length of 285 mm, ensures uniform and predictable light distribution. OSRAM technology guarantees long-term luminous flux stability and compliance with European standards. Energy class G reflects the typical energy consumption profile of high-power discharge lamps, offset by high luminous efficiency.

Advantages of NAV-E Sodium Technology

Compared to other lighting sources, the NAV-E sodium lamp combines long service life, energy efficiency, and low cost. The lower color rendering index (Ra <25) is typical of sodium technology but is not a limitation in applications where color fidelity is not critical. Ideal for those seeking a reliable and cost-effective solution for technical lighting of large areas.
