High-pressure sodium lamp NAV E 400 SUPER 4Y 410W E40 4050300024394

High-pressure sodium lamp – reliable industrial and outdoor lighting

This 400W E40 base high-pressure sodium lamp from Osram is a proven choice for illuminating large open spaces. Known for its high luminous efficiency, it is ideal for areas where bright and effective lighting is essential. The lamp emits a warm, yellow light with a color temperature of 2000K, making it particularly visible in atmospheric conditions such as fog or smoke.

Characteristics and application

The NAV E 400 SUPER 4Y lamp features an ellipsoidal bulb shape (ED37 type) and a matte finish, which ensures even light distribution. This minimizes glare and improves viewing comfort. Its robust construction guarantees a long service life – up to 32,000 hours of operation. Requires the use of an external ballast and igniter, which is standard for high-pressure lamps. The luminous flux at 55,400 lm with a power of 400W provides very good luminous efficacy – 138 lm/W.

It finds application primarily in:

• Street lighting: ideal for illuminating roads, parking lots and sidewalks.
• Industrial lighting: will work in production halls, warehouses and industrial areas.
• Sports lighting: perfectly suited for illuminating pitches, stadiums and other sports facilities.
• Advertising lighting: can be used to illuminate billboards and other outdoor advertising elements.
• Agriculture: although not specifically designed for plant lighting, it can be used in greenhouses as an additional light source (in combination with other types of lamps).

Advantages and benefits for professionals and end users

• High luminous efficiency: 138 lm/W means lower energy costs while maintaining an adequate level of lighting. This translates into savings for both companies and individual users.
• Long service life: 32,000 hours of operation minimizes the need for frequent lamp replacement, reducing maintenance costs and downtime.
• Clearly visible in difficult conditions: Sodium light is less scattered by fog or smoke than light from other sources, increasing safety and comfort.
• Proven manufacturer: The lamp comes from Osram – a world leader in lighting production, which guarantees high quality workmanship and reliability.
• Suitable for demanding applications: Thanks to its construction and technical parameters, the lamp performs perfectly in demanding working conditions – both indoors and outdoors.
• Energy saving: Despite the high power, the lamp is characterized by efficient use of electricity (energy consumption per 1000 hours: 451 kWh).

Please remember that the lamp does not contain mercury and requires the use of an external ballast and igniter for proper operation. The color rendering index (CRI) is in the range of 20-39, which means poorer color reproduction than modern LED light sources. However, its advantages related to luminous efficiency and durability compensate for this inconvenience in many industrial and outdoor applications.
