Product Description
200W DC EmArc® enhanced metal arc lamp with integrated 70mm reflector — optimized for high-efficiency optical and fiber coupling.
 
Overview

The Ushio SMR-200D1 (Ordering Code: 5001399) is a 200W DC EmArc® Enhanced Metal Arc reflectorized lamp engineered to deliver high luminance from a tightly confined arc into compact optical trains. The integrated 70mm reflector is aligned for maximum throughput through a 6mm aperture at a 52mm working distance from the reflector rim, making it a strong fit for imaging and fiber-optic illumination systems where collection efficiency matters.

Key Highlights
  • Rated Power: 160–200W (DC), nominal 200W
  • Lamp Electrical: 43V / 4.65A nominal
  • Arc Gap: 1.2 mm (high radiance class)
  • Color Temperature: 6500K (projection/“white” imaging class)
  • Optical Output Reference: 5100 lm measured through 6mm aperture (at 52mm from reflector rim)
  • Reflector: Integrated 70mm reflector (aligned for optical coupling)
  • Average Rated Life: 2000 hours (life definition depends on duty cycle/output depreciation method)
Where It’s Used
  • Medical and scientific fiber optic illumination (endoscopy, headlights, specialty illumination)
  • Machine vision, microscopy, and precision imaging platforms
  • Industrial optical systems where compact arc geometry improves coupling efficiency
  • OEM optical assemblies designed around SMR-series reflectorized EmArc® lamps
Compare & Contrast: SMR-200D1 vs SMR-201/D1 vs SMR-202/D1 (Same Family)
If your system is aperture-limited or you need to tune coupling efficiency, these related models are commonly evaluated side-by-side:
Model Arc Gap Nominal CCT Through-Aperture Output Reference Typical Use Case
SMR-200/D1 1.2 mm 6500K 5100 lm / 6mm aperture (52mm WD) Tight aperture / strong coupling
SMR-201/D1 1.6 mm 6500K 5500 lm / 8mm aperture (52mm WD) Slightly larger aperture collection
SMR-202/D1 2.0 mm 6900K 5900 lm / 10mm aperture (52mm WD) Higher throughput at larger apertures
Important: Do not substitute based on wattage alone. Match exact model + reflector geometry, electrical characteristics (V/A), and the OEM ballast/driver specification.
Safety Notice (High Pressure Arc Lamp)
Arc discharge lamps operate at high temperature and pressure and require a properly engineered lamp housing. Install only in enclosed, interlocked systems with appropriate shielding and cooling. Allow full cool-down before service. This product contains mercury; handle and dispose/recycle per applicable regulations.
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 while underlying specifications remain consistent. SOSCleanroom will continue to supply and support specialty lamps and can help validate continuity by part number and critical specs.

How EmArc® Delivers High Coupling Efficiency

EmArc® is a DC arc-discharge technology that blends rare gas and metal additives to create a tightly confined plasma discharge. The 1.2 mm arc-gap class supports high luminance (radiance), which improves collection into small apertures and fiber bundles where étendue is limited.

Ushio describes EmArc® designs as using precise filling control, electrode design, and tight manufacturing tolerances to maintain arc stability and reduce optical artifacts (shadowing), while supporting long-life operation relative to traditional discharge options in similar applications.

Ballast / Power Supply Pairing (System-Level Requirement)
SMR-series EmArc® reflector lamps require a compatible DC electronic power supply with appropriate ignition and current regulation. Power supply choice impacts arc stability, hot re-ignition performance, and life.
Ushio Power Supply Where It Fits Why It Matters
SmartArc™ ELDC 2.31 (Item #5002001) Power supply for EmArc® lamps Digital power management for DC arc stabilization (OEM integration dependent)
SmartArc™ UBX 76 (Item #5001569) For EmArc® & DC gas discharge lamps Compact “intelligent” control architecture (match ignition/current spec to your housing)
Best practice: Validate ignition method, operating current regulation, cooling, interlocks, and optical alignment requirements per your OEM system documentation.
Safety & Compliance Notes
High-pressure arc lamps require robust shielding and interlocks. Never operate outside an approved lamp housing. Allow full cool-down before handling. Contains mercury; manage disposal per applicable regulations. Follow applicable warning guidance for mercury and California Proposition 65 where required.
Industry Update (Ushio + ams OSRAM ENI)
ams OSRAM announced the sale of its Entertainment & Industry Lamps (ENI) business to Ushio, 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 part-number and specification continuity checks.
