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

The Ushio EKE is a precision 150W, 21V halogen lamp in the MR16 reflector format, designed to deliver a bright, stable beam for instruments that depend on consistent illumination and repeatable optical performance. It uses a GX5.3 bi-pin base and is commonly specified as JCR21V-150W. SKU: EKE (1000306).

  • Electrical: 150W, 21V
  • Description: JCR21V-150W
  • Base: GX5.3 Bi-Pin
  • Type: Halogen lamp with MR-16 reflector
  • Color Temperature: 3,300K
  • Shape: MR16 (50.7mm diameter)
  • Average Life: 200 hours
  • UPC: 048777119952
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.
About Ushio
Ushio is a global photonics and specialty lighting company that develops light sources and light-based solutions used across industrial applications (including semiconductor-related markets), visual imaging, and life sciences. Ushio’s “Applying Light to Life” focus reflects a broad portfolio that includes specialty lamps, LED/laser technologies, and integrated lighting systems.
Industry Update:
In July 2025, Ushio announced an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing anticipated by the end of March 2026. During and after a transition, customers may see changes such as branding, labeling, packaging, and distribution channels. Best practice: qualify replacements by the manufacturer code and critical specs (150W/21V, GX5.3, and MR16 geometry) to ensure continuity.

The Science: How a Halogen Bulb Produces Light
A halogen lamp is a form of incandescent light source. Electrical current passes through a tungsten filament, and the filament’s resistance converts energy into heat. At operating temperature, the filament becomes white-hot and emits continuous-spectrum light (visible light plus infrared) due to thermal radiation.
The “halogen” advantage comes from the halogen cycle. Inside a quartz (high-silica) envelope, an inert fill gas is combined with a small amount of halogen (commonly iodine or bromine). Tungsten that evaporates from the filament can react with the halogen to form tungsten-halide compounds. Near the hotter filament region, these compounds dissociate and redeposit tungsten back onto the filament. This helps reduce glass blackening and supports higher filament temperatures for strong, stable output—while also requiring careful handling because the lamp operates at high temperature.
Industry Update: ams OSRAM ENI Business → Ushio (Expected Close by End of March 2026)
Ushio announced an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing anticipated by the end of March 2026.
What this means for buyers: during and after the transition, customers may see changes in branding, part-number presentation, packaging, origin labeling, or channel availability across certain specialty lamp families. To reduce risk, qualify replacements by electrical specs (150W/21V), base (GX5.3), and MR16 geometry, and retain the manufacturer code (EKE / 1000306) in maintenance records.
Common Cross-References (Verify Before Ordering)
Common identifiers include: EKE, JCR21V-150W, and 150W 21V MR16 GX5.3. Always verify voltage and base type before substituting—MR16 lamps may look similar while using different electrical ratings.
Replacement & Handling Notes
  • Match electrical specs: use 150W / 21V only. Incorrect voltage can damage equipment or shorten lamp life.
  • Confirm base & format: GX5.3 pin geometry and MR16 reflector dimensions are critical for fit and optical performance.
  • Keep the envelope clean: avoid fingerprints and residues that can create localized hot spots. Use clean nitrile gloves and/or a lint-free wipe.
  • Plan spares: typical rated life is 200 hours; keep spares for critical instruments.
Cleanroom Considerations

Treat lamp changes as a controlled maintenance step: minimize packaging debris, use low-lint handling materials, and keep the lamp 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 the lamp and optical path.
