High-pressure sodium lamp with increased luminous flux 250W WLS City250 E40 WLS-3004

High-pressure sodium lamp – reliable industrial and outdoor lighting

This 250W high-pressure sodium lamp is a proven choice for lighting outdoor areas, industrial halls, warehouses, and spaces where high luminous efficiency is required. The WLS City250 E40 model from Helios is distinguished by increased luminous flux and longer life compared to standard sodium lamps. This translates to less frequent replacement and lower operating costs.

Features and application

The WLS City250 lamp is designed for versatility. The ability to operate in any position makes it possible to mount it both vertically and horizontally, adapting to the specifics of the installation. Thanks to the improved design, it offers approx. 18% higher luminous flux than traditional sodium lamps, which provides better lighting while maintaining energy efficiency. Additionally, faster restart (approx. 1 min) compared to metal halide and mercury lamps minimizes downtime in the event of a power failure.

It is important to remember that the lamp is intended for use only in luminaires equipped with appropriate electrical equipment – a series-parallel ignitor (3.5-4.5kV) and a magnetic or electronic ballast.

Advantages for professionals and end-users

• Higher efficiency: Increased luminous flux provides better lighting with lower energy consumption.
• Longer life: Means less frequent replacement and reduced maintenance costs.
• Versatility: The ability to operate in any position makes installation and adaptation to different conditions easier.
• Fast restart: Minimizes downtime after a power failure – especially important in industrial and public facilities.
• Compliance with standards: The product meets the requirements of PN-EN 62035, PN-EN 60662 and PN-EN 61547 standards, which guarantees safety and reliability.
• Ecology: Remember to dispose of used lamps properly – they contain mercury and cannot be thrown away with household waste. Return them to the place of purchase or to a collection point for waste electrical and electronic equipment.

Remember: proper selection of the luminaire and electrical equipment is crucial for the correct operation of the lamp and ensuring its long life.
