Product Description
High-output single-ended halogen quartz lamp for stage, studio, and precision illumination systems requiring stable 3200K output.
 
Overview

The Ushio JCD120V-300WC is a 300W, 120V single-ended halogen quartz lamp built for fixtures that need high luminous output and consistent color performance. It uses a GY9.5 prefocus bi-pin base and a compact G7 envelope to support tight optical systems in entertainment and specialty lighting applications. SKU: JCD120V-300WC (1000896).

Key Highlights
  • Electrical: 300W, 120V
  • Base: GY9.5
  • Bulb Shape / Finish: G7, Clear
  • Color Temperature: 3200K
  • Light Output: 7500 lm
  • Average Life: 100 hours
  • Burn Position: BD/HZ (base down to horizontal)
  • Dimensions: 22.0 mm dia • 63.5 mm MOL • 36.5 mm LCL
Typical Applications
  • Stage / studio / broadcast lighting fixtures specifying JCD120V-300WC (or equivalent)
  • Optical systems using prefocus bi-pin halogen sources (GY9.5)
  • Equipment requiring 3200K “tungsten balance” output for consistent color rendering
Compare & Contrast (What to Match Before Substituting)
Many 300W halogen lamps appear similar, but fixture performance depends on base type (GY9.5), envelope size (G7), light center length (LCL), and burn position limits. If your system references an ANSI code (commonly DYS in this class), qualify by exact part number + critical geometry to protect focus and beam quality.
Handling Tip
Halogen quartz lamps run extremely hot and are sensitive to surface contamination. Avoid touching the glass with bare hands. Use clean nitrile gloves and allow full cool-down before removal.
Industry Update (Ushio & ENI Continuity)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. During transitions, customers may see changes to branding, labeling, or packaging. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.

Halogen Quartz Science (Why These Lamps Hold Output)

Halogen quartz lamps use a tungsten filament inside a quartz envelope with a halogen fill gas. At operating temperature, evaporated tungsten can be driven back toward the filament (the “halogen cycle”), helping preserve lumen maintenance and reduce blackening compared to non-halogen incandescent lamps. This is one reason 3200K studio-class halogen sources remain a standard for repeatable color appearance in many legacy fixtures.

In optical fixtures, light center length (LCL) is a critical parameter—LCL shifts can change focal position, beam shape, and hot-spot alignment. When replacing, prioritize LCL and base geometry alongside wattage and voltage.

Cross-Reference & Fixture Matching
Common documentation may reference this lamp class as DYS (300W / 120V / GY9.5). Always verify:
  • Base: GY9.5 (prefocus)
  • Envelope: G7
  • LCL: 36.5 mm
  • Burn position: BD/HZ
Matching these reduces focus drift and optical misalignment.
Safety & Handling
Operates at high temperature. Avoid touching quartz glass with bare hands. Use clean gloves and ensure fixtures are powered down and cooled before service. Maintain fixture shielding, airflow, and wattage compliance to reduce risk of overheating.
Industry Update (Ushio + ams OSRAM ENI)
Ushio has an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. Customers may see branding/packaging transitions across some legacy lamp lines during and after integration. SOSCleanroom will continue supporting specialty lamps and can assist with continuity validation by part number and critical specs.
