Product Overview
The Osram 54837 EKB is a photo-optic specialty halogen lamp engineered for professional projection and optical instrument applications requiring precise filament positioning, consistent color temperature, and reliable performance in OEM equipment. Osram photo-optic halogen lamps are built to tight optical tolerances — delivering consistent color temperature, high CRI, and stable light output that makes them the trusted OEM and replacement choice for professional medical, dental, microscopy, and projection equipment worldwide.
The GZ9.5 bipin base is a standard projection lamp base — confirm the exact base type specified by your equipment manufacturer, as some instruments specify GZ9.5, GY9.5, or GX9.5 depending on the lampholder design. Always confirm lamp code, wattage, voltage, and base designation against your equipment's service manual before ordering a replacement.
Compatible Applications
- Professional projection systems — Slide projectors, overhead projectors, and specialty optical projection equipment specifying ANSI EKB.
- Medical and dental equipment — Examination, surgical, and dental instrument lighting using 420W 120V halogen sources.
- Microscopy and scientific instruments — Optical instruments requiring precise filament positioning and consistent color output.
- Stage and studio lighting — Professional entertainment and broadcast fixtures specifying EKB-designated lamps.
Before Ordering — Verify
- ANSI Code: Confirm your equipment manual specifies EKB. Projection lamps are equipment-specific — always verify against OEM documentation.
- Voltage: Confirm equipment is rated for 120V. Do not install in higher-voltage equipment.
- Wattage: Confirm the fixture or equipment is rated for 420W.
- Base Type: Confirm the lampholder accepts GZ9.5 Bipin. Verify exact base designation (GZ9.5, GY9.5, or GX9.5) with your equipment's service documentation.
- Photometric Data: Confirm CCT, lumens, LCL, and rated life against the Osram specification sheet for critical optical applications.
Safety and Handling Guidelines
- Do not touch the quartz envelope with bare hands. Skin oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
- Approved Enclosed Fixtures Only: Use only in fixtures designed and approved for 420W halogen operation with appropriate UV shielding.
- High-Pressure Lamp: Operates under high internal pressure. Handle with care. Do not use a cracked or damaged lamp.
- Allow Complete Cool-Down: Allow the lamp to cool fully before handling or replacement.
- Do Not Exceed Rated Voltage: Operating above 120V dramatically shortens lamp life.
Compliance
- Verify RoHS compliance status, UL listing, and additional certifications with the Osram manufacturer specification sheet prior to use in regulated or medical installations.
