High-pressure sodium lamp NAV E 50/E 50W E27 4050300015750

High-pressure sodium lamp – reliable lighting for demanding applications

This high-pressure sodium lamp, known for its high luminous efficacy, is a proven choice for outdoor, industrial and street lighting. Manufactured by a renowned manufacturer, LEDVANCE (formerly OSRAM), it combines durability and efficiency, offering a long-lasting and economical solution. This product is designed to operate with an external ballast and igniter.

Characteristics and application

The VIALOX NAV-E lamp with a power of 50W and an E27 base emits warm light with a color temperature of 2000K, making it ideal for applications where precise color rendering is not required. A luminous flux of 3600 lm provides good visibility in various conditions. Thanks to its construction, the lamp is designed for operation in both open and closed luminaires – although in the case of outdoor applications, appropriate luminaires must be used. It will be perfect on streets, parking lots, industrial areas and other places requiring intense and reliable lighting.

Advantages and benefits

• High luminous efficacy: 72 lm/W means efficient energy use and lower operating costs.
• Long lifespan: Average durability of 24,000 hours minimizes the need for frequent lamp replacement.
• Proven technology: Product from a market leader – LEDVANCE – guarantees high quality and reliability.
• Versatility: Possibility of use in open and closed luminaires increases the scope of applications.
• Appropriate light color: Color temperature of 2000K provides visual comfort in many outdoor applications.
• Economy: Energy consumption at the level of 55 kWh per 1000 hours of operation allows to reduce costs related to lighting.
• Durable construction: Made of high-quality materials providing resistance to weather conditions (when using appropriate luminaire).

Construction and parameters

The lamp is characterized by an ellipsoidal shape of the bulb and a matte finish, which ensures even light distribution. Its compact dimensions (total length 156 mm, diameter 71 mm) make it easy to install in various types of luminaires. It should be remembered that the lamp requires the use of an external ballast and igniter for proper operation. The lack of mercury content is another plus for the natural environment – although it is important to remember about responsible disposal of used lamps. The color rendering index (CRI) is in the range of 20-39, which means limited possibilities for faithful color reproduction – therefore, the lamp works best where this aspect is not key.
