Product Description
Instrument-grade HLX/XENOPHOT halogen capsule for microscopy and precision optical illumination.
SOSCleanroom
Overview

The Osram / Sylvania HLX 64610 (ANSI BRL) is a precision 50W, 12V low-voltage halogen capsule built for stable, repeatable illumination in microscopes and other optical instruments. “HLX” identifies OSRAM’s XENOPHOT technology, where xenon replaces the typical fill gas to support strong performance and improved lumen maintenance in demanding applications. This listing is a 10-pack. SKU: BRL (54249).

Key Highlights
  • Electrical: 50W, 12V
  • ANSI Code: BRL
  • Mfg. Ordering Code: 54249
  • Base: G6.35 Bi-Pin
  • Shape: T3.5
  • Average Life: 50 hours
  • Pack Quantity: 10 bulbs
  • UPC: 4050300006697
Typical Applications
  • Microscope illuminators and optical instruments
  • Ophthalmic and medical imaging systems using low-voltage bi-pin capsules
  • Precision inspection equipment where filament position and stable output matter
Handling Tip 
Halogen capsules 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 by the end of March 2026. During and after transitions in specialty lamp portfolios, customers may see changes such as labeling, packaging, and part-number presentation across certain lamp families. Best practice: qualify replacements by the manufacturer ordering code and critical specs (50W/12V, G6.35, and T3.5 geometry), and retain HLX 64610 / BRL / 54249 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 more 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 the transaction expected to close by the end of March 2026.
What this means for buyers: across certain specialty lamp lines, customers may encounter changes in labeling, packaging, or channel availability during the transition. To reduce risk, qualify replacements by 50W/12V, G6.35, and capsule geometry, and keep the manufacturer ordering code (54249) in maintenance records.
Replacement & Handling Notes
  • Match electrical specs: use 50W / 12V only. Incorrect voltage can cause rapid overheat/failure or insufficient output.
  • Confirm base & filament position: G6.35 fit and filament alignment affect coupling into reflectors/light paths and overall brightness.
  • Keep the envelope clean: fingerprints/residues can create localized hot spots. Use clean nitrile gloves and/or a lint-free wipe.
  • Pack management: this is a 10-pack; store spares sealed and clean to reduce contamination during maintenance events.
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.
