Product Description
Single-ended halogen lamp (ANSI ESR) for professional fixtures requiring a BA15d double-contact bayonet base.
 
Overview

The Ushio ESR is a compact 100W, 120V quartz tungsten-halogen lamp designed for stable, repeatable output in enclosed fixtures that use a BA15d (double contact bayonet) socket. Common catalog identification: ESR, JCV120V-100WGB2. Ushio Item Code: 1000364.

Key Highlights
  • Electrical: 100W, 120V
  • ANSI Code: ESR
  • Base: BA15d (double contact bayonet)
  • Bulb Shape: T4 (clear)
  • Color Temperature: 2850K (nominal)
  • Burning Position: Any (universal)
  • Filament: CC-2V (industry standard for ESR family)
Typical Applications
  • Professional entertainment / studio fixtures that specify ANSI ESR
  • Mole-Richardson fixtures commonly listed for ESR applications (e.g., Type 2351 / Type 2901)
  • Specialty luminaires using BA15d double-contact bayonet sockets
Selection Tip (ESR vs Similar BA15d Lamps)
For correct replacement, qualify by ANSI ESR first, then confirm 120V, 100W, and base BA15d. Similar-looking bayonet-base lamps can differ in contact style, filament geometry, and operating characteristics.
Handling Tip
Halogen lamps run hot and are sensitive to contamination. Avoid touching the glass with bare hands. Use clean nitrile gloves and/or a lint-free wipe, and operate only in approved enclosed fixtures designed for halogen sources.
Industry Update (Ushio & ENI Continuity)
Ushio has signed an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. During transitions like this, customers may see changes to branding, labeling, or packaging—even when underlying lamp specifications remain consistent. SOSCleanroom will continue to support specialty lamps and can help qualify continuity by part number and critical specs.
Need help selecting the right product?
Always confirm ANSI code (ESR), voltage (120V), wattage (100W), and base type (BA15d) prior to installation.

Lamp Science (Halogen Cycle + Why BA15d Matters)

ESR is a quartz tungsten-halogen source: a tungsten filament operates at high temperature inside a halogen environment. In properly designed enclosed luminaires, the halogen regenerative cycle helps reduce envelope darkening and supports more consistent output over time than non-halogen incandescent sources.

The BA15d double-contact bayonet base provides repeatable mechanical indexing and robust electrical contact. In high-heat fixtures, socket condition matters: weak spring pressure or oxidized contacts can create resistive heating at the base, accelerating lamp and socket wear.

Compare & Contrast (ESR vs ESN / “Other 100W Bayonet Lamps”)
Lamps may share a similar bayonet form factor but differ in contact style (single vs double contact), filament geometry, and color temperature. For continuity, qualify by ANSI ESR first—then confirm BA15d, 120V, and 100W.
Cross-Reference (Common Market Equivalents)
ESR is commonly cross-listed as 100Q/CL/DC style references in some legacy catalogs and may appear under various manufacturer numbers. When cross-referencing, treat ANSI code + voltage + base as the controlling specs, then verify output/CT if color matching is critical.
Safety & Fixture Requirements
Operate only in approved enclosed fixtures designed for halogen lamps. Maintain ventilation paths and keep the lamp envelope clean to avoid hot spots. Always allow full cool-down before handling.
