Product Description
Pre-focused 6.5V microscope illumination lamp—built for consistent alignment and reliable instrument lighting (10 pack).
SOSCleanroom
Overview

The 1460X is an incandescent microscope replacement bulb designed for microscopy illumination where repeatable filament positioning matters. Its DC pre-focus base is engineered to seat consistently in compatible sockets, helping maintain light placement and uniformity within the microscope’s optical system. SKU: 1460X. Supplied as a 10 pack.

Key Highlights
  • Electrical: 18W, 6.5V, 2.75A
  • Base: DC Pre-Focus (alignment-focused seating)
  • Shape: S Shape
  • Technology: Incandescent
  • Average Life: 100 hours (application dependent)
  • Pack Size: 10 bulbs
Typical Applications
  • Microscope illumination systems
  • Scientific, medical, and dental microscopes and related optical instruments
Common Cross-References (Examples)
1460X is commonly referenced under codes such as GE 1460X, Ushio SM-1460X / SM1460X, SOS FU-2852, and Bausch & Lomb codes (including 31-31-75 and 31-31-76). Always qualify by the electrical rating and pre-focus base style.
Handling Tip 
For best life and optical performance, avoid touching the glass with bare hands. Use clean nitrile gloves and/or a lint-free wipe. In controlled environments, cleanroom-grade low-lint handling materials help reduce residue and particulates around the lamp housing and optics.
Service Note
SOSCleanroom (Specialty Optical Systems, Inc.) has supported specialty lighting customers as a distribution partner for 40+ years. For microscope bulbs, the correct fit is driven by voltage/wattage, base seating, and filament position—not just the part number.

The Science: How an Incandescent Microscope Bulb Produces Light
Incandescent instrument lamps generate light by heating a tungsten filament. When electrical current passes through the filament, the filament’s resistance converts electrical power into heat. At operating temperature, the filament becomes white-hot and emits continuous-spectrum light (visible light plus infrared) through thermal radiation.
For microscopes, the usable result is not only brightness—it is repeatable light placement. That is why instrument bulbs use precise filament geometry and base seating: the optical system is designed around where the filament “sits” relative to collectors, condensers, field diaphragms, and the illumination pathway.
Why the DC Pre-Focus Base Matters
  • Filament position is an optical requirement: even small shifts can reduce coupling efficiency, change the illuminated field, or introduce non-uniform brightness.
  • Repeatable seating: pre-focus bases are built to “land” consistently in the socket so the filament returns to the intended focal relationship after replacement.
  • Reduced troubleshooting: using the correct base style helps avoid symptoms that look like “optics issues” but are actually lamp alignment problems.
Power, Voltage Discipline, and Life Drivers
  • Designed for 6.5V operation: microscope illuminators typically rely on regulated or transformer-based low voltage. Stable voltage supports stable output.
  • Over-voltage shortens life: higher filament temperature increases evaporation and can dramatically reduce service life.
  • Hot switching and vibration: frequent on/off cycling at full power and mechanical shock can accelerate filament fatigue.
  • Thermal management: keep airflow paths clear; excess heat in the lamp house can stress sockets, wiring, and nearby optics.
Replacement Checklist (Avoid Costly Mis-Matches)
  • Match electrical rating: 6.5V and 18W (and the expected current draw).
  • Match base style: DC pre-focus seating is a functional requirement for alignment, not just a connector.
  • Confirm envelope/shape: the lamp must clear the lamp house and maintain the intended optical geometry (S shape).
  • Validate illumination performance: after replacement, confirm field uniformity, brightness, and the ability to focus/adjust the illumination as expected.
Cross-Reference Guidance (Common Names You May See)
Installed bases often reference the same lamp under different supplier codes. Examples associated with 1460X-style replacements include:
  • GE: 1460X
  • Ushio: SM-1460X / SM1460X / SM-1460
  • Bausch & Lomb: 31-31-75, 31-31-76, 31-01-05
  • Reichert / American Optical / AO: commonly referenced in older microscope platforms
  • Other: Swift MA760 / MA 760, SOS FU-2852 (varies by documentation)
Best practice: use cross-references as a starting point, then qualify by 6.5V / 18W, DC pre-focus base, and fitment in your lamp housing.
Cleanroom Considerations

Treat bulb changes like a minor maintenance event: minimize packaging debris, protect reflectors and lenses from particulates, and keep the lamp envelope free of oils and residue.

Stage clean nitrile gloves plus cleanroom-grade lint-free wipes/swabs during service to reduce contamination risk around the illumination path.

For microscopes, confirm OEM requirements (voltage, wattage, base seating, and illumination geometry). If your scope manual lists multiple equivalent codes, always qualify by the electrical rating and the pre-focus base style.
