Product Description
Low-voltage HLX quartz halogen capsule for microscopy, lab/analysis, fiber illumination, UV curing, and surgical/dental lighting systems.
 
Overview

The Osram / Sylvania 64602 is a precision 50W, 12V single-ended quartz tungsten-halogen lamp designed for optical systems that require repeatable light coupling and stable illumination in a compact envelope. This lamp uses a G6.35 bi-pin base and is widely specified in microscopy, laboratory & analysis platforms, fiber illumination systems, UV curing equipment, and surgical/dental overhead lighting where consistent output and filament alignment matter.

Key Highlights
  • Electrical: 50W, 12V (low-voltage)
  • Base: G6.35 bi-pin
  • Nominal Output: 1000 lumens
  • Color Temperature: 3050K
  • CRI: Ra 100
  • Light Center Length (LCL): 30 mm
  • Average Life: 1100 hours
  • Burn Position: s90
  • Lamp Type: HLX quartz halogen (single-ended)
Typical Applications
  • Microscopy illumination and optical instruments
  • Laboratory & analysis equipment
  • Fiber illumination light engines
  • UV curing platforms specifying this low-voltage halogen architecture
  • Surgical & dental overhead lighting systems
Selection Tip
In instrument lighting, filament placement + LCL can be as important as voltage and wattage. If your system specifies 64602, qualify by 12V / 50W, G6.35, and LCL 30 mm to maintain optical coupling and alignment.
Handling Tip
Quartz halogen capsules are sensitive to surface contamination. Avoid touching the glass with bare hands. Use clean nitrile gloves and/or a lint-free wipe to minimize residue and reduce hot-spot failure risk.
Industry Update (Branding & Supply Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During this transition, customers may notice changes to branding, labeling, packaging, or invoicing entity even when the underlying lamp specification remains the same. SOSCleanroom will continue to support these lamps and can help qualify continuity by part number and critical specs (voltage, wattage, base type, and key optical dimensions) to ensure you receive the correct product across branding changes.
Need help selecting the right product?
We can help verify low-voltage requirements and optical qualifiers (LCL/geometry) to prevent mis-matches in microscope and instrument platforms.
Always confirm compatibility with your equipment model, required voltage (12V), wattage (50W), base type (G6.35), and any specified optical dimensions (LCL 30 mm) prior to installation.

Lamp Science (Why HLX Matters in Instruments)

In microscopy and fiber illumination, the “system performance” is often limited by how well the source couples into an optical train (condenser, aperture stop, or fiber bundle). HLX-style lamps emphasize filament alignment and geometric repeatability, so optical coupling remains consistent after lamp changes. The specified illuminated field (3.0 × 3.0 mm²) and LCL (30 mm) are practical qualifiers for systems that image or focus the filament.

Quartz halogen chemistry supports the regenerative “halogen cycle,” reducing envelope darkening and helping maintain output stability across life compared to non-halogen incandescent sources—important when instruments require repeatable illumination for imaging, measurement, or inspection.

Compare & Contrast
Compared to higher-output, shorter-life families (common in projection MR16 reflector lamps), 64602 is positioned as a longer-life instrument capsule with controlled geometry and stable color rendering. Use 64602 when your system is built around G6.35 + LCL 30 mm + s90 and prioritizes repeatable optical coupling.
Cross-Reference Notes (Qualification-First)

Use these qualifiers to prevent mis-matches: 64602 (Global order reference), 54607 (Americas product number), LIF M/134, 12V / 50W, G6.35, and LCL 30 mm. Equivalent listings may exist from other manufacturers when matching these exact electrical and geometric requirements; verify dimensional clearance and optical alignment requirements prior to substitution.

Safety & Handling
Halogen lamps should be operated only in suitable luminaires/equipment with protective mechanisms (shields/guards) appropriate to the application. Avoid skin oils on quartz. Ensure full insertion and good socket tension to prevent intermittent contact and localized heating.
Industry Update (Ushio & ENI Continuity)
Ushio is scheduled to assume the U.S. Entertainment & Industry (ENI) lamp business as the legal contracting entity effective March 1, 2026. During the transition, branding or packaging updates may occur even when lamp specifications remain unchanged. SOSCleanroom will continue supporting these lamps and qualifying continuity by part number and critical specifications.
