The 100W high-pressure sodium lamp with an E40 screw base and elliptical outer bulb. Producing approximately 8,500 lumens of warm amber light, this long-life HID lamp is ideal for street lighting, security lighting, industrial sites, warehouses, and other large-area applications.
What it is
The 100W E40 Elliptical High-Pressure Sodium Lamp is a high-intensity discharge lamp designed for efficient, long-duration lighting in commercial, industrial, municipal, and outdoor environments.
Its elliptical outer bulb protects the internal sodium discharge tube, while the E40 Goliath screw base provides a secure connection in compatible heavy-duty luminaires. Producing approximately 8,500 lumens, the lamp delivers strong amber-toned illumination well suited to applications where visibility, long operating life, and low maintenance are more important than accurate colour rendering.
Unlike standard household bulbs, an HPS lamp requires compatible control gear to regulate current and start the discharge process.
Use Cases / Applications
Ideal for high-output commercial, municipal, and industrial lighting applications, including:
- Street and roadway lighting
- Security and perimeter lighting
- Industrial yards
- Warehouses and storage facilities
- Factories and manufacturing plants
- Parking areas
- Loading bays
- Agricultural buildings
- Building exteriors
- Municipal and utility lighting
Key Benefits
- Produces approximately 8,500 lumens of high-output illumination
- Long operating life helps reduce replacement and maintenance frequency
- Suitable for extended nightly operation
- Strong luminous efficiency for conventional HID lighting
- E40 base supports compatible commercial and industrial luminaires
- Elliptical outer bulb protects the internal discharge assembly
- Proven technology for roadway, security, and infrastructure lighting
- Reliable replacement for compatible 100W HPS installations
High-pressure sodium lamps create light through an electrical discharge inside a sodium-filled arc tube. This technology produces the characteristic amber-gold light associated with streetlights and prioritises efficiency and long service life over colour accuracy.
