150W high-pressure sodium lamp with an E40 Goliath screw base and coated elliptical outer bulb. Producing approximately 13,700 lumens of amber 2,000K illumination, this long-life Philips HID lamp is ideal for roadway lighting, security areas, industrial sites, parking facilities, and municipal installations.
What it is
The SON-E 150W E40 Elliptical High-Pressure Sodium Lamp is a high-intensity discharge lamp designed for efficient, dependable illumination in municipal, industrial, commercial, and outdoor environments.
Its coated elliptical outer bulb provides a softer, more diffused light distribution than a clear tubular HPS lamp, while the E40 Goliath screw base provides a secure connection in compatible heavy-duty luminaires.
Producing approximately 13,700 lumens of characteristic amber-gold 2,000K light, this lamp is well suited to applications where long operating life, high luminous efficiency, and broad-area visibility are more important than accurate colour rendering.
Unlike ordinary household lamps, the SON-E requires compatible 150W HPS control gear to ignite the arc tube and regulate current during operation.
Use Cases / Applications
Ideal for high-output commercial, municipal, 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 and crossings
- Agricultural buildings
- Building perimeter lighting
- Municipal and utility installations
- Existing luminaires designed for a 150W E40 HPS lamp
Key Benefits
- Produces approximately 13,700 lumens
- Luminous efficacy of approximately 93 lumens per watt
- Long nominal operating life of approximately 28,000 hours
- Suitable for prolonged nightly operation
- Coated elliptical bulb provides softer, more diffused illumination
- E40 base suits heavy-duty commercial and industrial luminaires
- Universal operating position offers flexible installation
- Proven technology for roadway, security, and infrastructure lighting
High-pressure sodium lamps generate light through an electrical discharge inside a sodium-filled ceramic arc tube. This creates the distinctive amber-gold output associated with conventional street lighting and prioritises efficiency, visibility, and long service life over precise colour reproduction.
Safety Compliance
- Requires compatible 150W HPS control gear
- May require a ballast, ignitor, and power-factor correction capacitor, depending on the luminaire
- Control gear should include appropriate end-of-life protection
- Must not be connected directly to mains power without the correct control gear
- Requires warm-up time before reaching full brightness
- May require a cooling period before restriking after interruption
- Install only in a suitably rated HID luminaire
- Isolate the electrical supply and allow the lamp to cool before replacement
- Dispose of through an approved HID lamp-recycling channel
