Equipment compatibility

Equipment and application fit

Used in track, display, retail, museum, gallery, and accent lighting

  • Use only in equipment whose lamp list and electrical, optical, thermal, and mechanical design specify this exact lamp or a fully documented equivalent.

Socket fit alone does not establish compatibility. The equipment label, current service manual, and installed-lamp marking take precedence.

Confirm any substitute against the complete electrical, mechanical, optical, filament, dimensional, and operating specification. A shared ANSI code may identify a lamp family but does not override equipment requirements.

Documentation & safety

Manufacturer documentation and handling

Halogen safety: Disconnect power and allow the equipment to cool before service. Install only in approved enclosed equipment with the required protective screen, ventilation, electrical controls, and shielding. Handle quartz with clean gloves or lint-free tissue and avoid touching the envelope with bare skin.
