400W mercury blended lamp with an E40 Goliath screw base and elliptical outer bulb. Producing approximately 13,000 lumens of neutral white illumination, this self-ballasted HID lamp operates directly from the mains without external control gear, making it ideal for warehouses, factories, agricultural buildings, workshops, and high-bay security lighting.
What it is
The 400W E40 Elliptical Mercury Blended Lamp is a self-ballasted high-intensity discharge (HID) lamp designed to provide dependable illumination in commercial, agricultural, industrial, and utility lighting applications.
Unlike conventional mercury vapour lamps, a mercury blended lamp incorporates an internal tungsten filament that acts as its ballast, allowing the lamp to operate directly from a standard 220–240V mains supply without requiring an external ballast or ignitor.
Producing approximately 13,000 lumens of neutral white illumination, this lamp is ideal for replacing existing mercury blended installations where simple installation, long service life, and reliable performance are required.
