Product Description
High-output single-ended halogen quartz lamp for stage, studio, and projection fixtures requiring tight optical focus and stable 3200K output.
 
Overview

The Ushio JCD120V-800WC is a 800W, 120V halogen single-ended quartz lamp designed for high-intensity “tungsten-balance” illumination where beam focus, color consistency, and fixture compatibility are critical. This lamp uses a GY9.5 prefocus base and a compact G8 envelope to support optics that depend on repeatable filament position. SKU: JCD120V-800WC (1000909).

Key Highlights
  • Electrical: 800W, 120V
  • Base: GY9.5 (prefocus bi-pin)
  • Bulb Shape / Finish: G8, Clear
  • Color Temperature: 3200K
  • Initial Lumens: 19,500 lm
  • Efficacy: 24.4 lm/W
  • Average Life: 75 hours
  • Burn Position: BD/HZ (base down to horizontal)
  • Dimensions: 24.0 mm dia • 62.0 mm MOL • 36.5 mm LCL
  • Front Glass Cover: No
Typical Applications
  • Stage / studio / broadcast fixtures specifying JCD120V-800WC or compatible GY9.5 prefocus lamps
  • Projection and special effects lighting where filament alignment controls beam quality
  • Optical systems needing 3200K “tungsten” appearance for consistent color rendering
Compare & Contrast (What Matters Most in Substitution)
Many 800W halogen lamps are electrically similar, but fixture performance depends on GY9.5 prefocus geometry, Light Center Length (LCL), and envelope size. If LCL changes, focus shifts—impacting beam shape, hotspot position, and overall intensity where it’s needed. Best practice is to qualify by exact part number + LCL (36.5 mm) rather than wattage alone.
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 (What Drives Performance)

Halogen quartz lamps operate a tungsten filament at high temperature inside a quartz envelope with a halogen fill gas. The halogen cycle helps return evaporated tungsten to the filament, reducing bulb blackening and supporting more stable lumen maintenance than non-halogen incandescent sources in similar form factors.

For optical fixtures, geometry is as important as electrical rating. The prefocus GY9.5 base and LCL (36.5 mm) control filament placement in the reflector system. Substitution with a different LCL or base type can shift the focal point and distort beam quality.

Qualification Checklist (Before You Substitute)
Match these to protect focus and fixture safety:
  • Voltage / wattage: 120V / 800W
  • Base: GY9.5 (prefocus)
  • LCL: 36.5 mm
  • Envelope: G8, clear
  • Burn position: BD/HZ
Safety & Handling
Operates at very high temperature. Avoid touching quartz glass with bare hands (use clean gloves). Ensure fixtures are powered down and cooled before service, and confirm the fixture is rated for 800W operation with proper shielding and airflow.
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.
