Product Description
High-output MR16 halogen reflector lamp (ANSI ELC) for projection, optical instruments, and precision illumination systems.
 
Overview

The Ushio ELC is a 250W, 24V tungsten-halogen lamp in the MR16 reflector format, designed for high-intensity optical systems where beam control and filament alignment directly affect performance. Identified by ANSI ELC and commonly listed as JCR24V-250W, this lamp uses a GX5.3 bi-pin base and is widely specified in projection equipment, microscopy, and fiber-optic light engines.

Key Highlights
  • Electrical: 250W, 24V
  • ANSI Code: ELC
  • Base: GX5.3 bi-pin
  • Shape: MR16 reflector (clear)
  • Color Temperature: 3400K (nominal)
  • Average Life: 50 hours (nominal)
  • Burning Position: Base Down (BD)
Typical Applications
  • 16mm / slide / microfilm projection systems
  • Microscopes and laboratory optical benches
  • Fiber-optic and endoscopic illumination sources
  • Scientific and inspection equipment requiring controlled beam geometry
Selection Tip (ELC vs Similar MR16 Lamps)
MR16 lamps can share the same GX5.3 interface yet differ in voltage, filament geometry, and reflector design. For correct replacement, qualify by ANSI ELC first, then confirm 24V, 250W, and required burn position. Substituting a different MR16 variant can shift focus and alter light coupling efficiency.
Handling Tip
Halogen lamps operate at elevated temperatures and are sensitive to surface contamination. Avoid touching the quartz or reflector with bare hands. Use clean nitrile gloves or a lint-free wipe. Verify transformer output (24V systems) under load to prevent over-voltage conditions that shorten lamp life.
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 the transition, customers may notice branding or packaging updates even when lamp specifications remain unchanged. SOSCleanroom will continue to support specialty lamps and can assist with continuity validation by part number and critical specifications.
Need help selecting the right product?
Always confirm ANSI ID (ELC), voltage (24V), wattage (250W), base (GX5.3), and fixture burn orientation prior to installation.

Lamp Engineering & Optical Performance

The ELC is a quartz tungsten-halogen reflector lamp. The tungsten filament operates at elevated temperature inside a halogen gas environment, enabling the regenerative halogen cycle. This process helps redeposit evaporated tungsten back onto the filament, reducing envelope darkening and maintaining luminous stability over the lamp’s rated life.

In projection and fiber-optic systems, the MR16 reflector geometry and controlled filament placement determine beam divergence and coupling efficiency. Light center length and reflector precision are critical; incorrect substitutes can shift focal alignment and reduce system performance.

Cross Reference & Substitution Guidance
Commonly referenced as ELC or JCR24V-250W. When evaluating alternates, verify voltage (24V), wattage (250W), base (GX5.3), reflector type, and burn position. Do not substitute 21V or 120V MR16 lamps in 24V systems.
Industry Update (Ushio & ams OSRAM ENI)
Ushio has signed an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps business, with closing expected by the end of March 2026. Branding and packaging updates may occur during the transition, while core specifications remain consistent. SOSCleanroom continues to support these specialty lamps and assists customers with part-number validation and continuity planning.
