The Osram 64435-U Halostar is a high-performance 24V halogen capsule designed for precision lighting and accentuation. This 20-watt T3 lamp features an axial filament, which is meticulously aligned to ensure optimum directional light and maximum luminous intensity when used in reflectors. Built with specialized UV-reducing quartz, it effectively suppresses unwanted UV radiation, complying with the strict protection thresholds of IEC 60432-3. With a perfect CRI of 100 and tempered base pins to prevent corrosion, this G4 bi-pin lamp delivers brilliant, warm white light (3000K) ideal for high-end residential fixtures and specialized commercial equipment.

Brilliant Light with UV Protection

The Halostar 24V series is engineered for those who require the highest quality of light without the risks associated with ultraviolet exposure. The integrated UV-filter protects sensitive surfaces and prevents the fading of illuminated objects, making it a reliable choice for galleries and high-end retail displays. Its compact T3 shape and axial filament design allow for precise beam control in small luminaires. Furthermore, the pins are tempered to ensure a long-lasting, corrosion-free electrical connection, providing a consistent 1,000-hour rated life and smooth dimming capabilities.

• Axial Filament: Optimized for use in reflectors to provide superior directional illumination.
• UV-Filter Technology: Drastically reduces UV emission for safer lighting of sensitive materials.
• Superior Color: CRI 100 (Ra=100) ensures colors are rendered with absolute fidelity.
• Corrosion Resistance: Tempered pins protect the lamp base against oxidation in humid or high-heat environments.
