OSRAM SYLVANIA 54446 | EYB 360W 82V Halogen Lamp

The Osram Sylvania 54446 (EYB) is a high-performance single-ended halogen lamp engineered for critical illumination requirements in technical display systems, precision optical equipment, and specialized medical projectors. Operating at **82V**, this **360W** quartz lamp features a high-grade G5.3 ceramic 2-pin base designed to withstand extreme thermal environments. With a color temperature of **3250K** and a maximum **CRI of 100**, it delivers stable, high-intensity natural white light with perfect color rendering accuracy throughout its specialized 75-hour operating lifespan.

Precision Engineering for Optical Instrumentation

Designed with a precision-coiled CC-8 filament, the Sylvania EYB lamp generates an intensely focused, high-clarity beam pattern that eliminates distortion in optical setups. Its premium hard glass envelope features advanced UV-blocking properties to protect sensitive downstream equipment components. To maintain system reliability and prevent premature burnout, this lamp requires operation in the designated **s90 position** (vertical ±90 degrees) inside fixtures utilizing robust, heat-resistant ceramic sockets.

• Instant Activation: Reaches full, unfiltered brightness instantly without any warmup period.
• Maximum Heat Resistance: Ceramic base ensures mechanical stability under heavy industrial or clinical runtimes.
• Exceptional Color Rendering: True CRI 100 accuracy allows for precise visual inspection and medical scanning.
• Stable Luminous Flux: Halogen cycle chemical configuration keeps the quartz wall free of dark carbon deposits.
