High-pressure sodium lamp NAV E 50/I 50W E27 4050300015583

High-pressure sodium lamp – reliable lighting for demanding applications

This high-pressure sodium lamp NAV E 50/I 50W E27 is a proven choice for professionals and users looking for an efficient and durable light source. The manufacturer, LEDVANCE, is known for its high-quality lighting products, and this lamp is no exception. It is characterized by high luminous efficacy, which translates to energy savings and lower operating costs.

The lamp is designed to operate with an external ballast, which ensures its stable operation and long life. Its power of 50W generates a luminous flux of 3600 lm, providing bright and effective lighting. A color temperature of 2000 K provides warm, yellow light, which is well suited for street lighting, outdoor lighting and industrial installations.

Characteristics and application

The NAV-E/I sodium lamp is an ideal solution where reliability and durability are important. It will work in demanding atmospheric conditions (in appropriate luminaires), as well as in places exposed to frequent switching on and off. Thanks to its construction, it is suitable for both open and closed lighting fixtures.

• Applications:
  • Street lighting
  • Outdoor lighting (gardens, parking lots)
  • Industrial installations (production halls, warehouses)
• Key features:
  • Power: 50W
  • Base: E27 – standard thread for easy replacement
  • Luminous flux: 3600 lm – high luminous efficiency
  • Average lifespan: up to 24,000 hours – minimizes the need for frequent replacement
  • Luminous efficacy: 72 lm/W – efficient energy use
  • Color temperature: 2000 K – warm, yellow light

Construction and parameters affecting performance

The lamp's construction has been designed with long-term operation in mind. The ellipsoidal shape of the bulb ensures even light distribution. It is worth noting the color rendering index (CRI) of 20-39 – although this is not a high value, typical of sodium lamps, it is sufficient for most outdoor and industrial applications where visibility is a priority rather than accurate color reproduction. The lamp does not contain mercury, making it more environmentally friendly (although proper disposal is required). Energy consumption per 1000 hours is 55 kWh - which allows you to estimate operating costs. The total length of the lamp is 156 mm with a diameter of 71 mm - these dimensions should be taken into account when selecting the luminaire.
