Product Description
High-output 1000W linear halogen double-ended quartz lamp (R7s-12) for equipment needing intense, uniform line-source illumination.
 
Overview

The Ushio J120V-1000WB is a 1000W, 120V halogen double-ended quartz lamp engineered in a linear T4 envelope with an R7s-12 base. This format is widely used when systems require a strong, even “bar” of light for optical assemblies, heating/processing stations, or legacy specialty fixtures that qualify by ANSI and geometry. SKU: J120V-1000WB (1000695).

This lamp is commonly cross-referenced as Q1000T3/CL-120V and qualifies under ANSI: J-1000. For continuity, always match the R7s-12 base, overall length (191.1 mm), and contact-to-contact (185.7 mm).

Key Highlights
  • Electrical: 1000W, 120V
  • ANSI Code: J-1000
  • Cross Reference: Q1000T3/CL-120V
  • Base: R7s-12 (double-ended)
  • Bulb: T4, Clear
  • Color Temperature: 2900K
  • Initial Lumens: 22,000 lm
  • Rated Life: 2,000 hours
  • Burn Position: Any
  • Geometry: 191.1 mm MOL • 185.7 mm contact-to-contact • 12.0 mm diameter
  • Other: UV Protected • Ozone Free
Typical Applications
  • Specialty fixtures and legacy systems specifying J-1000 / J120V-1000WB / Q1000T3/CL-120V
  • Graphic arts and process equipment using linear R7s lamps
  • Optical assemblies needing high output and consistent line-source geometry
Compare & Contrast (What to Match Before Substituting)
Many “1000W R7s” lamps look interchangeable, but performance (and safe fit) depends on the exact mechanical spec. Match these first: R7s-12 base, MOL 191.1 mm, contact-to-contact 185.7 mm, and T4 diameter 12.0 mm. If length or contact spacing differs, lamps can seat incorrectly, shift the optical line source, or stress lampholders.
Handling Tip
Double-ended halogen quartz lamps run extremely hot. Avoid touching the quartz with bare hands—oils can create hot spots and shorten life. Use clean nitrile gloves and ensure the fixture’s protective lens/guard is installed per equipment requirements.
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. Customers may see changes to branding, labeling, or packaging during transitions. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.
Need help selecting the right product?
Confirm ANSI J-1000 / Q1000T3/CL-120V equivalency, R7s-12 base, and mechanical length (191.1 mm MOL; 185.7 mm contact spacing) before installation.

Why Double-Ended Quartz Halogen (R7s) is Used

The double-ended quartz format supports a long, high-power filament in a compact tube while keeping the light source aligned as a uniform line. In systems that image, mask, or spread light across a width, the linear filament geometry helps deliver consistent intensity compared to point-source lamps.

As a halogen lamp, the quartz envelope and halogen fill enable the “halogen cycle,” which helps reduce tungsten deposition on the tube and supports better lumen maintenance versus non-halogen incandescent designs under similar thermal loading.

Cross-Reference (Common Identifiers)
This lamp is commonly referenced as:
  • Ushio: J120V-1000WB / Item Code 1000695
  • ANSI: J-1000
  • Industry cross-ref: Q1000T3/CL-120V
  • Base class: R7s-12 (double-ended)
Qualification tip: prioritize mechanical match (MOL + contact spacing + base) before brand name or shorthand codes.
Safety & Handling
High-wattage quartz halogen lamps operate at very high temperature. Use clean gloves (avoid skin oils on quartz), allow full cool-down before service, and keep fixture guarding/protective glass in place as required by the equipment design. Confirm lampholders are rated for 1000W service and proper contact spacing.
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.
