Compatibility Check

Verify that your fixture and ballast are rated for a 100 watt pulse-start metal halide lamp with the correct base type. Ensure the enclosure can handle the operating temperature and that the supply voltage matches the ballast requirements. This lamp is not a direct retrofit for incandescent or standard metal halide sockets without a compatible ballast.

Suitable Applications

Ideal for users needing high-efficacy daylight-quality light with 25 percent better maintained output and 50 percent faster warm-up and restrike. Not suited for buyers who want instant-on capability, dimming control, or a lamp that operates on standard household sockets without dedicated HID gear. Those seeking lower colour temperatures or plug-and-play LED alternatives should consider other options.
