With CRI 100, 3000K warm white color temperature, 900 initial lumens, and a rated life of 2,000 hours, this lamp is engineered for display, medical, optical, and specialty commercial lighting applications where UV suppression and color accuracy are required. The lamp is dimmable and complies with IEC 60432-3 UV protection thresholds. Verify voltage, wattage, and base type before ordering.

Technical Specifications

Product Overview

The Osram 64445 Halostar is a precision T4 halogen lamp engineered for applications where UV suppression, full-spectrum color accuracy, and directional light control are critical. The UV-reducing quartz envelope suppresses unwanted ultraviolet radiation and complies with IEC 60432-3 — making this lamp well suited for use near UV-sensitive materials, artworks, merchandise displays, and environments where UV exposure must be controlled.

The axial filament design provides optimum directional light output, maximizing illuminance in focused beam applications. Corrosion-resistant tempered base pins ensure reliable electrical contact over the lamp's service life. CRI 100 delivers full-spectrum color rendering identical to natural daylight — the highest possible color fidelity available in a halogen source. The lamp is dimmable and operates at 24V — confirm your fixture or transformer is rated for this voltage before ordering.

Compatible Applications

• Display and retail lighting — Museum cases, retail showcases, and merchandise displays where UV suppression protects sensitive items.
• Medical and scientific equipment — Instruments and examination lighting requiring CRI 100 and controlled UV output.
• Architectural and hospitality accent lighting — High-end accent and task lighting systems using 24V GY6.35 halogen lamps.
• Specialty optical and studio applications — Equipment requiring an axial filament for precise directional control.

Before Ordering — Verify

• Voltage: Confirm the fixture or transformer is rated for 24V operation.
• Wattage: Confirm the fixture is rated for 50W.
• Base Type: Confirm the socket matches GY6.35 Bi-Pin.
• Physical Fit: Confirm 44mm MOL and 12mm diameter fit within your fixture's lamp housing.
• UV Requirement: If UV suppression is required, confirm this is the UV-reducing quartz variant (Halostar 64445) — not a standard halogen equivalent.

Safety and Handling Guidelines

• Do not touch the quartz envelope with bare hands. Skin oils cause hot spots that can lead to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
• Correct Voltage Required: Use only with 24V compatible fixtures or transformers. Incorrect voltage will cause immediate failure or drastically reduce lamp life.
• Allow Cooling: Allow the lamp and fixture to cool fully before handling or relamping. Halogen lamps operate at very high surface temperatures.
• Approved Fixtures Only: Install only in fixtures rated for the listed wattage and voltage.

Compliance

• UV-reducing quartz complies with IEC 60432-3 UV protection thresholds.
• Verify RoHS compliance status and additional certifications with the Osram manufacturer specification sheet prior to use in regulated installations.
