400W high-pressure sodium lamp with an E40 Goliath screw base and opal elliptical outer bulb. Producing approximately 48,000 lumens of warm amber 2100K illumination, this Eurolux HID lamp is ideal for roadway lighting, industrial sites, warehouses, security lighting, parking facilities, and municipal infrastructure.
What it is
The 400W E40 Elliptical High-Pressure Sodium Lamp is a high-intensity discharge (HID) lamp engineered to provide powerful, energy-efficient illumination across commercial, municipal, agricultural, and industrial environments.
Its opal elliptical outer bulb delivers a softer and more diffused light distribution than a clear tubular lamp, while the heavy-duty E40 Goliath screw base provides a secure connection in compatible HID luminaires. Producing approximately 48,000 lumens of characteristic amber 2100K illumination, this lamp is designed for applications where high light output, long operating life, and broad-area visibility are more important than colour accuracy.
Unlike conventional household lamps, this HPS lamp requires compatible 400W HID control gear, including a ballast and ignitor, for safe and correct operation.
Use Cases / Applications
Ideal for high-output commercial, municipal, agricultural, and industrial lighting applications, including:
- Street and roadway lighting
- Security and perimeter lighting
- Industrial yards
- Factory exteriors
- Warehouses and storage facilities
- Parking areas
- Loading bays
- Railway yards
- Agricultural buildings
- Building perimeter lighting
- Municipal and utility installations
- Existing luminaires designed for a 400W E40 HPS lamp
Key Benefits
- Produces approximately 48,000 lumens
- High luminous efficacy of approximately 120 lm/W
- Long nominal operating life of approximately 20,000 hours
- Suitable for prolonged nightly operation
- Opal elliptical bulb provides softer, more diffused illumination
- E40 base suits heavy-duty commercial and industrial luminaires
- Reliable replacement for compatible HPS lighting systems
- Proven technology for roadway, security, municipal, and industrial lighting
High-pressure sodium lamps generate light through an electrical discharge inside a sodium-filled ceramic arc tube. This technology produces the familiar amber-gold light associated with street lighting and prioritises efficiency, visibility, and long service life over precise colour reproduction.
Safety Compliance
- Requires compatible 400W HPS control gear
- Requires a compatible ballast and ignitor
- Must not be connected directly to mains voltage
- Allow sufficient warm-up time before reaching full brightness
- Hot restrike may require a cooling period before restarting
- Install only in luminaires designed for 400W HPS lamps
- Isolate power before installation or replacement
- Dispose of responsibly through an approved HID lamp recycling programme
