Osram Xenophot® 54250 (64633 HLX) Halogen Lamp — 150W | 15V Low Voltage | 5,600 Lumens | G6.35 Bi-Pin Base

The Osram Xenophot® Professional 54250 (64633 HLX) Lamp is an entertainment and medical-grade, high-intensity low-voltage tungsten halogen capsule engineered exclusively for laboratory microscopes, ophthalmic slit lamps, surgical diagnostic instruments, dental examination tracks, and high-magnification overhead slide projection systems. Delivering 5,600 initial lumens of crisp 3300K studio white illumination, this premium single-ended bulb features an authoritative ANSI BRJ / LIF A1/234 specification tracking profile and utilizes an advanced Xenophot (HLX) fill gas matrix—where high-pressure xenon gas replaces traditional krypton—to achieve up to 10% higher luminous efficiency while maintaining standard power parameters. Outfitted with a heavy-duty G6.35 bi-pin base and a high-purity clear T4 quartz glass envelope, it ensures perfect optical focal alignment across its 50-hour calibrated technical service life.

ADL Supply Expert Application & Replacement Guide

The Osram 64633 HLX low-voltage technical capsule is an established medical, clinical laboratory, and photographic baseline specified universally across clinical diagnostics bays, automated blood chemistry analyzers, surgical examination monitors, and high-contrast material inspection stations. Featuring a precision-aligned flat planar filament positioned perfectly within its clear transparent casing, this lamp delivers an intense full-spectrum point light beam. This allows laboratory pathologists, ophthalmic surgeons, and material quality technicians to capture absolute color rendering accuracy and fine structural depth without experiencing the frequency gaps or visual color casting common in alternative solid-state replacements.

Critical 15V Low-Voltage Transformer Parameters and G6.35 Seating Safety Controls: Facility engineers and medical field contractors executing routine instrument maintenance must verify circuit configuration metrics closely prior to checkout: this capsule runs natively on low-voltage 15V line tracks and requires a compatible step-down magnetic transformer or stabilized electronic DC power supply to operate safely. Connecting or bridging this 15V module directly across standard 120V or 277V primary building branch circuits will trigger instant high-amperage over-drive failure, prompting immediate filament vaporization and an explosive quartz capsule breakdown.

Furthermore, ensure the dual pins—spaced on an absolute 6.35mm center-to-center pitch—slide fully and straight into the fixture socket blocks. Because driving a high thermal density 150-watt load across a compact G6.35 contact footprint requires minimum line resistance, any loose wire contact or internal pin tracking will invite localized arcing loops, causing high contact resistance that transcends the base's maximum safe **350°C maximum safe thermal limit** and damages the host instrument's delicate socket assembly.

Operation, Safety & Mounting Compliance

High-Temperature Regenerative Halogen Halide Cycle Controls

This halogen lamp operates via an internal chemical loop where vaporized tungsten particles bond with halogen gas molecules inside the heated chamber. This compound cycles back onto the burning filament tracks, redepositing the tungsten to preserve filament mass. For this cycle to work cleanly and prevent wall-blackening, the inner envelope must continuously transcend a high temperature threshold exceeding 250°C, making proper convective venting inside track cylinders or medical instrument shrouds mandatory.

Safety and Installation Guidelines

• Use only in approved enclosed halogen fixtures
• Disconnect power before installing or removing lamp
• Allow lamp to cool before handling
• Use clean gloves or lint-free cloth to avoid quartz contamination
• Confirm correct system voltage before operation

Additional Information

In the Osram Xenophot version, xenon is used as the filling gas instead of standard fill gas technology. This allows the lamp to achieve up to 10% higher luminous efficiency while maintaining the same power consumption. Xenophot lamps are identified by the HLX abbreviation in the product catalog.
