High-pressure sodium lamp NAV E 50W SUPER 4Y 50W E27 4008321356024

High-pressure sodium lamp – reliable industrial and outdoor lighting

A high-pressure sodium lamp is a proven choice for illuminating large spaces, both indoors and outdoors. It is characterized by high luminous efficiency and long life, which translates to energy savings and less frequent replacement. The NAV E 50W SUPER 4Y model is a product of a renowned manufacturer, guaranteeing solid construction and stable operation.

Characteristics and application

This 50-watt lamp with an E27 base emits a luminous flux of 4000 lumens with a luminous efficacy of 77 lm/W. A color temperature of 2000 K provides warm, yellow light that works well in street lighting, parking lots, industrial areas, and in agriculture. It should be remembered that the lamp requires an external ballast and igniter for proper operation. Its ellipsoidal shape and matte finish ensure even light distribution.

• High efficiency: Energy consumption of 58 kWh per 1000 hours of operation is a good result compared to traditional light sources.
• Long life: The average rated lifespan of 28000 hours minimizes costs associated with bulb replacement.
• Versatility: Ideal for outdoor (streets, parking lots) and industrial (production halls, warehouses) lighting.
• Renowned manufacturer: The product comes from a market leader in lighting, guaranteeing high quality and reliability.
• Suitable for harsh conditions: It will work in places requiring intense lighting for a long time.

Construction and assembly

The lamp has a diameter of 71 mm and a total length of 156 mm. Its E27 base allows for easy installation in standard fixtures. It should be remembered to use an external ballast and igniter – this is crucial for the correct functioning of the lamp. It is also worth noting that the product does not contain mercury, which is beneficial from an environmental point of view (although proper disposal of used lamps should be remembered). The color rendering index (CRI) is in the range of 20-39, which means poorer color reproduction compared to other light sources – it is worth considering this when choosing a lamp for applications requiring precise color reproduction.
