Product Description
Low-voltage MR16 dichroic reflector halogen lamp (ANSI EBV) for microscopy, lab/analysis, UV curing, fiber illumination, and dental/medical overhead lighting.
 
Overview

The Osram / Sylvania 64637 is a precision 100W, 12V quartz tungsten-halogen lamp built in the MR16 reflector format for controlled, repeatable illumination in optical and instrument platforms. This lamp is commonly identified by ANSI EBV and features a dichroic reflector that helps manage heat in compact optical heads by transmitting a portion of infrared through the reflector while maintaining a focused visible beam. (Americas reference: 54223.)

Key Highlights
  • Electrical: 100W, 12V (low-voltage)
  • ANSI Code: EBV
  • LIF Code: A1/271
  • Shape: MR16 Reflector
  • Base: GZ6.35 bi-pin
  • Beam Type: SP (spot)
  • Color Temperature: 3000K
  • Average Life: 1500 hours (nominal)
  • Reflector Coating: Dichroic
Typical Applications
  • Microscopy illumination systems
  • Laboratory & analytical instruments
  • UV curing systems specifying MR16 low-voltage reflectors
  • Fiber optic illumination and light engines
  • Surgical & dental overhead lighting platforms
Selection Tip (Prevent Mis-Matches)
Many MR16 lamps look similar but differ in voltage, base type, reflector behavior, and beam geometry. For correct replacement, qualify by ANSI EBV plus 12V, then confirm base GZ6.35 and beam type (SP) to match your equipment’s optical requirements.
Handling Tip
Halogen reflector lamps run hot and are sensitive to contamination. Avoid touching the glass/reflector with bare hands. Use clean nitrile gloves and/or a lint-free wipe to minimize residue and reduce hot-spot failure risk. Allow full cool-down before removal.
Industry Update (Branding & Supply Continuity)
Effective March 1, 2026, the OSRAM Entertainment & Industry lamp business in the United States transitions to Ushio America, Inc. as the legal contracting entity under Ushio ownership. 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 (EBV / 12V / 100W / MR16 / GZ6.35).
Need help selecting the right product?
Always confirm compatibility with your equipment model, required voltage (12V), ANSI EBV specification, beam type (SP), and base type (GZ6.35) prior to installation.

How It’s Built (HLX Pinch + Dichroic Reflector Physics)

This lamp is part of OSRAM’s HLX reflector family, designed around controlled quartz pinch manufacturing to support precise filament-to-reflector alignment. In optical and instrument lighting, small shifts in filament position can change beam intensity at the target and alter coupling efficiency into optics or fiber systems.

The dichroic reflector is engineered to reflect most visible wavelengths while transmitting a portion of infrared through the reflector. This design can reduce forward heat loading on sensitive optics or targets in compact light heads (actual temperatures depend on fixture airflow and thermal design).

Compare & Contrast (What Most Commonly Goes Wrong)
“MR16” describes the reflector diameter, not the electrical or optical identity. Substituting a different MR16 can change voltage, base, beam type, and focal behavior. For continuity, treat ANSI EBV + 12V + GZ6.35 + SP as the controlling match set.
Safety & Fixture Requirements
Halogen lamps may only be operated in suitable luminaires designed with protective mechanisms (shields/grids) to ensure that, in the unlikely event of lamp bursting, no parts can escape and that during operation no ultraviolet radiation can escape. Allow full cool-down before handling.
Industry Update (Ushio & ENI Continuity)
Effective March 1, 2026, the OSRAM Entertainment & Industry business in the United States transitions to Ushio America, Inc. as the legal contracting entity. During this transition, branding/packaging updates may occur even when specifications remain unchanged. SOSCleanroom will continue supporting these lamps and qualifying continuity by part number and critical specifications.
