When it may not be suitable
This lamp is not suitable for use in open luminaires, as it is strictly approved for operation within closed fixtures only. It should not be installed in residential settings or areas where the specific light spectrum and high-intensity output of a metal halide discharge lamp are not required.
Key specifications
Power rating: 400 W
Base type: E40
Technology: Metal halide with quartz technology
Color temperature: Daylight (5500K)
Dimensions: 62 mm x 285 mm
Safety: Integrated UV filter compliant with IEC 61167
How to use
The lamp must be installed into a compatible E40 socket within a closed luminaire. Ensure the power supply is disconnected before installation to prevent electrical hazards. Due to the nature of metal halide technology, the lamp requires a compatible ballast for proper ignition and operation. Once installed, allow the lamp to reach its full brightness during the warm-up period. Avoid touching the glass bulb with bare hands during installation to prevent residue buildup, which can affect performance.
What to consider before purchase
Verify that your existing luminaire is a closed-type fixture.
Ensure your lighting system is equipped with a compatible ballast for 400 W metal halide lamps.
Check the physical dimensions of the lamp to ensure it fits within your specific housing.
Confirm that the daylight color temperature (5500K) meets your application requirements.
Usage recommendations: For outdoor applications, ensure the lamp is housed in a weather-resistant, closed luminaire to protect it from environmental elements and ensure safe operation.
