## Long description

The Ledvance HQI-BT 400W is a high-performance metal halide lamp designed for professional lighting applications. Featuring an E40 base, this 400W discharge lamp provides efficient illumination for industrial, commercial, and outdoor floodlighting systems. It is engineered for reliability and consistent light output in demanding environments, making it an ideal choice for high-bay lighting and large area illumination.
Advantages
This metal halide lamp utilizes advanced quartz technology to deliver high luminous efficiency and a long operational lifespan. The inclusion of an integrated UV filter ensures that UV emissions remain significantly below the maximum permitted limits defined by international safety standards. The standard E40 socket design facilitates straightforward installation and handling in various industrial lighting fixtures.
Suitable for
Factories and workshops
Sports halls and multi-purpose halls
Industrial installations
Airports
Dry docks and port facilities
Deployment yards and container transfer facilities
This lamp is not suitable for use in open luminaires, as it is strictly approved for operation within closed lighting fixtures. It should not be installed in environments where the specific electrical requirements of a 400W metal halide discharge lamp cannot be met.
Key specifications
Power consumption: 400 W
Base type: E40
Technology: Metal halide with quartz technology
Dimensions: 62 mm x 285 mm
Color temperature: 5500K (Daylight)
Safety: Integrated UV filter
How to use
The lamp must be installed into a compatible E40 socket within a closed luminaire. Ensure that the electrical ballast and control gear are compatible with the 400W power rating of the lamp before installation. Due to the nature of metal halide technology, the lamp may require a short period to reach full brightness upon ignition.
What to consider before purchase
Verify that your existing luminaire is a closed type, as this is a mandatory safety requirement.
Ensure your lighting system is equipped with the correct ballast for a 400W metal halide lamp.
Confirm the physical dimensions of 62x285 mm fit within your specific fixture housing.
Usage recommendations
Always allow the lamp to cool down completely before attempting to replace it. Ensure that the glass bulb is not touched with bare hands during installation to prevent residue buildup that could affect performance.
