Match ANSI EHA, OSRAM 54585, and the equipment's 500W 120V GY9.5 requirement. A shared GY9.5 base does not make lamps interchangeable; voltage, wattage, filament geometry, dimensions, and light-center length must also match.

Need help confirming fit? Email help@dynamiclamps.com with the equipment manufacturer, model, and a clear photo of the existing lamp and equipment labels.

Equipment compatibility

Compatible-equipment references

This lamp is intended for professional equipment whose lamp label or service documentation specifies ANSI EHA / 500W 120V. Confirm the exact requirement before installation.

  • Slide and film projectors specifying ANSI EHA
  • Microfilm readers and reader-printers specifying ANSI EHA
  • Photographic and studio fixtures specifying ANSI EHA
  • Optical and projection systems specifying EHA 500W 120V with a GY9.5 base

Legacy equipment can have regional or production-run lamp changes. The equipment label and service manual take precedence over a model-family association.

Safety

Use only in equipment rated for a 500W 120V EHA lamp and fitted with the required protective lens, shield, or enclosure. Disconnect power and allow the equipment to cool before service. Handle the quartz with clean gloves or a lint-free cloth; remove fingerprints with suitable alcohol before operation.

High-output halogen lamps operate at high temperature and pressure. Keep combustible materials clear, maintain the equipment's airflow, and follow the equipment manufacturer's lamping, focus, and disposal instructions.
