Product Description
High-output MR16 halogen reflector lamp for microscope, medical, and scientific illumination.
SOSCleanroom
Overview

The Osram / Sylvania HLX 64627 (ANSI EFP) is a precision 100W, 12V halogen lamp in the MR16 reflector format, designed to deliver a bright, stable beam for microscopes and other optical systems where consistent illumination and repeatable performance matter. It is commonly referenced as JCR12V-100W and uses a GZ6.35 bi-pin base for secure fit and alignment. SKU: EFP (54189) EACH.

Key Highlights
  • Electrical: 100W, 12V
  • Description: JCR12V-100W
  • ANSI Code: EFP
  • Base: GZ6.35 Bi-Pin
  • Type: Halogen
  • Color Temperature: 3,350K
  • Shape: MR16 (50.7mm diameter)
  • Average Life: 50 hours
  • UPC: 046135541896
Typical Applications
  • Microscope illuminators and optical instruments
  • Medical and dental lighting systems using MR16 reflector lamps
  • Scientific and inspection equipment requiring consistent beam output
Handling Tip 
Halogen lamps run hot and are sensitive to surface contamination. Avoid touching the glass with bare hands. Use clean nitrile gloves and/or a lint-free wipe to minimize residue and reduce the risk of premature failure.
Industry Update:
In July 2025, Ushio and ams OSRAM announced an agreement for Ushio to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. During and after transitions in specialty lamp portfolios, customers may see changes such as labeling, packaging, and part-number presentation across certain lamp families. Best practice: qualify replacements by the manufacturer ordering code and critical specs (100W/12V, GZ6.35, and MR16 geometry), and retain HLX 64627 / EFP / 54189 in maintenance records.

The Science: How a Halogen Bulb Produces Light
A halogen lamp is a type of incandescent source. Electrical current heats a tungsten filament until it becomes white-hot, producing continuous-spectrum light (visible plus infrared) through thermal radiation.
The “halogen” advantage comes from the halogen cycle inside a quartz (high-silica) envelope: a small amount of halogen (often iodine/bromine) reacts with evaporated tungsten and helps transport it back toward the filament where it redeposits. This reduces envelope blackening and supports consistent output—while also driving high operating temperatures.
Industry Update: ams OSRAM ENI Business → Ushio (Expected Close by End of March 2026)
Ushio and ams OSRAM announced an agreement for Ushio to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026.
What this means for buyers: customers may encounter changes in labeling, packaging, or part-number presentation across certain specialty lamp lines during the transition. To reduce risk, qualify replacements by 100W/12V, GZ6.35, and the MR16 form factor, and keep the manufacturer ordering code (54189) in maintenance records.
Replacement & Handling Notes
  • Do not “voltage swap”: this is a 12V lamp; using a 21V/24V type (or vice versa) will cause incorrect output and may shorten lamp life.
  • Base fit matters: confirm GZ6.35 pin spacing and seating depth to avoid stress on the socket and optical misalignment.
  • Optical alignment is the point: MR16 reflector and filament geometry drive beam focus; match the exact code (EFP) when possible.
  • Keep the envelope clean: fingerprints/residues can create localized hot spots. Use clean nitrile gloves and/or a lint-free wipe.
Cleanroom Considerations

Treat lamp changes as a controlled maintenance step: minimize packaging debris, use low-lint handling materials, and keep the reflector and envelope free of oils and particulates prior to powering the instrument.

Stage clean nitrile gloves and a cleanroom-grade lint-free wipe during installation to reduce contamination risk and prevent residue transfer to nearby optics.
