Product Description
High-stability HLX/XENOPHOT halogen capsule for microscope and precision optical illumination.
SOSCleanroom
Overview

The Osram / Sylvania HLX 64621 is a precision 100W, 12V low-voltage halogen lamp designed for stable, repeatable illumination in demanding optical systems such as microscopy and medical/scientific instruments. “HLX” identifies OSRAM’s XENOPHOT technology, where xenon replaces the standard fill gas to help reduce tungsten vaporization and support strong output performance over service life. SKU: HLX 64621 (54032).

Key Highlights
  • Electrical: 100W, 12V
  • Base: 2-Pin (PG22)
  • Shape: T3
  • Length: 48mm
  • Initial Light Output: 2,880 lumens
  • Average Life: 2,000 hours
  • Ordering Code: 54032
Typical Applications
  • Microscope illuminators and optical instruments
  • Medical and scientific exam/inspection equipment requiring consistent light placement
  • Optical assemblies where filament position and stable output matter
Handling Tip 
Halogen lamps run hot and 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 the risk of premature failure.
Industry Update:
In July 2025, Ushio and ams OSRAM announced an agreement for Ushio to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected in Q1 2026 (by the end of March 2026). During and after transitions in specialty lamp portfolios, customers may see changes such as labeling, packaging, part-number presentation, and distribution channels across certain lamp families. Best practice: qualify replacements by the manufacturer code and critical specs (100W/12V, PG22, and key dimensions like 48mm), and retain HLX 64621 / 54032 in maintenance records.

HLX / XENOPHOT Note (Why It Matters)
“HLX” identifies OSRAM’s XENOPHOT halogen technology where xenon replaces krypton as the fill gas. In many optical applications, xenon can help reduce tungsten vaporization and support higher filament temperature—supporting strong output and consistent lumen maintenance.
The Science: How a Halogen Bulb Produces Light
A halogen lamp is a type of incandescent source. Electrical current heats a tungsten filament until it becomes white-hot, producing continuous-spectrum light (visible plus infrared) through thermal radiation.
The “halogen” advantage comes from the halogen cycle inside a quartz (high-silica) envelope: a small amount of halogen (often iodine/bromine) reacts with evaporated tungsten and helps transport it back toward the filament where it redeposits. This reduces envelope blackening and supports consistent output—while also driving high operating temperatures.
Industry Update: ams OSRAM ENI Business → Ushio (Expected Close by End of March 2026)
Ushio and ams OSRAM announced an agreement for Ushio to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected in Q1 2026 (by the end of March 2026).
What this means for buyers: customers may encounter changes in labeling, packaging, part-number presentation, or channel availability across certain specialty lamp lines during the transition. To reduce risk, qualify replacements by 100W/12V, PG22, and the lamp’s key dimensions, and keep the manufacturer ordering code (54032) in maintenance records.
Replacement & Handling Notes
  • Match electrical specs exactly: use 12V and 100W only. Incorrect voltage can cause rapid failure or insufficient output.
  • Confirm base & seating: PG22 fit and seating depth affect filament position and optical alignment.
  • Keep the envelope clean: fingerprints/residues can create localized hot spots. Use clean nitrile gloves and/or a lint-free wipe.
  • Protect optics during service: stage low-lint materials and keep packaging debris away from light paths and air inlets.
Cleanroom Considerations

Treat lamp changes as a controlled maintenance step: minimize packaging debris, use low-lint handling materials, and keep the capsule free of oils and particulates prior to powering the instrument.

Stage clean nitrile gloves and a cleanroom-grade lint-free wipe during installation to reduce contamination risk and prevent residue transfer to nearby optics.
