High-pressure sodium lamp NAV T 400 SUPER 4Y E40 4050300281179

High-pressure sodium lamp – reliable industrial and street lighting

This NAV T 400 SUPER 4Y E40 high-pressure sodium lamp from Osram is a proven choice for illuminating large spaces, both indoors in industrial buildings and outdoors – on streets, parking lots or recreational areas. Its construction based on HID (High Intensity Discharge) technology guarantees high luminous efficiency and long life. The lamp is characterized by a power of 400W and generates a luminous flux of 54800 lumens, providing intense and effective lighting.

Efficiency and durability for professionals

The NAV T 400 SUPER 4Y lamp was designed with demanding applications in mind. Its luminous efficacy is as high as 137 lm/W, which translates to energy savings compared to traditional light sources. The average rated life of 32000 hours minimizes the need for frequent replacement, reducing operating costs and downtime. It should be remembered that an external ballast and igniter are required for the lamp to function correctly.

Operating specifics and application

The characteristic C allows this lamp to react more slowly to short voltage surges, therefore it tolerates starting devices with an engine well. A color temperature of 2000K provides warm, yellow light, which works well in places requiring good visibility in low ambient light. Despite the relatively low color rendering index (CRI) in the range of 20-39, the lamp is perfect for applications where light intensity is a priority, and not faithful color reproduction. A transparent bulb ensures even light distribution.
