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)

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.
