Product Description
High-output MR16 halogen reflector lamp (ANSI ELH) for projection and specialty optical illumination.
 
Overview

The Osram / Sylvania ELH is a precision 300W, 120V quartz tungsten-halogen lamp built in the MR16 reflector format to deliver controlled, repeatable illumination for projection and specialty optical systems. It uses a GY5.3 bi-pin base and a dichroic reflector architecture that helps manage heat in optical heads by transmitting a portion of infrared through the reflector while maintaining a focused visible beam. (OSRAM global reference: 93518 | Americas product number: 54776.)

Key Highlights
  • Electrical: 300W, 120V (AC)
  • ANSI Code: ELH
  • Lamp Type: MR16 halogen reflector
  • Base: GY5.3 bi-pin
  • Filament: CC-8 (common projector filament geometry)
  • Reflector: Dichroic (heat-managing reflector design)
  • Nominal Output: 525 lumens
  • Color Rendering: Ra 100
  • Average Life: 35 hours (nominal)
Typical Applications
  • Overhead projectors and specialty projector heads specifying ANSI ELH
  • Slide / filmstrip / microfilm projection systems
  • Optical illumination assemblies where MR16 reflector focus is part of the design
  • Specialty entertainment and effect lighting systems that specify ELH
Selection Tip (ELH vs “Similar MR16”)
Many MR16 lamps share a similar physical size and bi-pin base but differ in voltage, filament geometry, and reflector optics. For correct replacement, qualify by ANSI ELH and 120V first—then confirm base (GY5.3) and fixture design requirements.
Handling Tip
Halogen reflector lamps operate at high temperature and are sensitive to contamination. Avoid touching the glass/reflector with bare hands. Use clean nitrile gloves and/or a lint-free wipe to reduce residue and hot-spot failure risk. Allow full cool-down before removal.
Industry Update (Branding & Supply Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During this transition, customers may notice changes to branding, labeling, packaging, or invoicing entity even when the underlying lamp specification remains the same. SOSCleanroom will continue to support these lamps and can help qualify continuity by part number and critical specs (ANSI code, voltage, wattage, and base type) to ensure you receive the correct product across branding changes.
Need help selecting the right product?
Always confirm compatibility with your equipment model, required voltage (120V), ANSI ELH specification, and base type (GY5.3) prior to installation.

Lamp Science (Why Dichroic MR16 Matters in Projection)

In projection and optical heads, the lamp is both a light source and an optical component. The CC-8 filament and MR16 reflector geometry are matched so the system can form a controlled image of the filament at the correct location in the optical train. Small differences in filament placement or reflector shape can shift focus, reduce uniformity, or change how efficiently light couples into the condenser or aperture.

A dichroic reflector is designed to reflect visible light while transmitting a portion of infrared through the reflector. This can help reduce forward heat load on slides/optics and improve thermal management in tightly packaged projector heads (fixture design still controls real-world temperatures).

Cross-Reference (Market Equivalents)
ELH is commonly cross-referenced across projector lamp catalogs. Typical equivalents include Ushio 1000321 (ELH / JCR120V-300W/MR16) and Eiko 02450 (ELH). For continuity, qualify by ANSI ELH + 120V + 300W + GY5.3 + MR16 dichroic reflector.
Safety & Handling
Operate only in fixtures designed for 300W halogen MR16 lamps with appropriate shielding and thermal management. Avoid skin oils on the lamp surface. Ensure the GY5.3 pins seat fully and that the socket maintains strong contact pressure to prevent resistive heating.
Industry Update (Ushio & ENI Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During the transition, branding or packaging updates may occur even when lamp specifications remain unchanged. SOSCleanroom will continue supporting these lamps and qualifying continuity by part number and critical specifications.
