400W mercury vapour lamp with an E40 Goliath screw base and opal elliptical outer bulb. Producing approximately 22,000 lumens of cool white 4000K illumination, this Eurolux HID lamp is ideal for warehouses, factories, workshops, security lighting, agricultural buildings, and commercial outdoor applications.
What it is
The Eurolux 400W E40 Elliptical Mercury Vapour Lamp is a high-intensity discharge (HID) lamp designed to deliver dependable, long-life illumination for commercial, industrial, agricultural, and utility lighting applications.
Its opal elliptical outer bulb provides a softer and more evenly distributed light, while the E40 Goliath Screw base allows installation into compatible mercury vapour luminaires. Producing approximately 22,000 lumens of cool white 4000K illumination, this lamp is well suited to installations where reliable performance, long operating life, and broad-area lighting are more important than energy efficiency.
Unlike mercury blended lamps, this mercury vapour lamp requires compatible HID control gear, including a ballast, for safe and correct operation.

Key Benefits
- Produces approximately 22,000 lumens
- Cool white 4000K illumination
- Long rated life of approximately 10,000 hours
- Suitable for prolonged daily operation
- Opal elliptical bulb provides softer, more diffused illumination
- E40 Goliath Screw base suits compatible mercury vapour luminaires
- Reliable replacement for existing mercury vapour installations

Mercury vapour lamps generate light through an electrical discharge inside a mercury-filled quartz arc tube. They provide a cool white output with good service life and have been widely used for industrial, warehouse, security, and high-bay lighting for decades.
Safety Compliance
- Requires compatible 400W mercury vapour ballast
- May require a compatible power factor correction capacitor depending on the luminaire
- 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 mercury vapour lamps
- Isolate power before installation or replacement
- Dispose of responsibly through an approved lamp recycling programme due to its mercury content
