OSRAM FDS/DZE 64642 HLX Xenophot Lamp — 150W | 24V Low Voltage | 5,000 Lumens | GY9.5 Prefocus Bi-Pin Base

The Osram Display/Optic 64642 HLX (FDS/DZE) Lamp is a professional-grade, high-intensity low-voltage tungsten halogen capsule engineered for clinical medical microscopes, slide projection equipment, overhead microfilm readers, architectural showcase spots, and high-fidelity machine vision tracks. Producing a brilliant 5,000 initial lumens of crisp 3400K photographic white light, this compact T4 bulb features an advanced ANSI FDS/DZE specification code tracking profile and utilizes an upgraded Xenophot (HLX) fill gas mix with a precision-coiled axial filament to achieve a flawless color rendering index of 100 CRI. Outfitted with a heavy-duty GY9.5 prefocus bi-pin base and a high-purity clear quartz envelope, it ensures perfect optical focal alignment across its 100-hour calibrated service life.

ADL Supply Expert Application & Replacement Guide

The Osram 64642 HLX flanged halogen capsule is an established industry photo-optic baseline specified universally across clinical diagnostics equipment, surgical operating projectors, high-magnification laboratory instruments, automated quality-control scanning tracks, and architectural profile spots. Utilizing high-density Xenophot technology—where premium xenon gas replaces standard krypton to elevate internal chamber pressure parameters—this bulb forces its axial tungsten filament to burn hotter, producing a raw, high-intensity "Photographic White" beam. This enables lighting designers and laboratory technicians to secure an absolute continuous full-spectrum projection layout, rendering accurate details without creating frequency gaps.

Critical 24V Step-Down Circuit Parameters and Mechanical GY9.5 Seating Controls: Field technicians and commercial contractors executing routine equipment repairs must verify system voltage parameters closely prior to checkout: this capsule runs natively on low-voltage 24V lines and requires a compatible step-down magnetic transformer or electronic power supply to operate. Connecting or bridging this 24V bulb across standard 120V or 277V mainline building grids will trigger immediate high-amperage over-drive failure, causing instant filament blowout or explosive quartz capsule fracturing.

Furthermore, the specialized GY9.5 base features a keyed bi-pin prefocus spacing dimension set at exactly 9.5mm center-to-center. Installers must slide the pins firmly into the fixture receiver slots until the capsule base sits completely flush against the seating collar. This precise mechanical placement aligns the filament core exactly along the fixture reflector's optical center, maximizing center-beam candlepower (CBCP) and preventing optical focus drift.

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 showcase track fixtures or medical instrument shrouds mandatory.
