SYLVANIA 54448 | EYB-5 360W 85.5V Halogen Specialty Projection Lamp

The Sylvania 54448 (EYB-5) is a high-performance quartz halogen specialty lamp engineered specifically for directional projection and precision optical systems. Operating at **85.5V**, this robust **360W** lamp features a specialized bi-pin configuration crafted to ensure exact filament alignment inside advanced equipment. As a foundational component of Sylvania's photo-optic specialty line, the EYB-5 lamp delivers exceptional, intense brightness, a flawless **CRI of 100** for perfect color rendering, and the tight manufacturing tolerances demanded by professional OEM hardware worldwide.

Precision Engineering for Demanding Optical Environments

Sylvania photo-optic lamps are designed to withstand the rigorous thermal and electrical conditions of scientific, stage, and professional projection systems. The **EYB-5 360-watt** bulb utilizes a heavy-duty quartz glass envelope that ensures clean, unfiltered light transmission throughout its lifespan. Because of the intense internal gas pressure and operating heat, this lamp must always be used within **approved enclosed halogen fixtures** designed to handle high-wattage specialty projection lamps safely.

• OEM-Grade Dependability: Built to precise mechanical tolerances in world-class facilities (USA / Germany) to ensure effortless drop-in fitment.
• Instantaneous Ignition: Reaches full lumen output and complete color accuracy immediately upon start up with no warm-up lag.
• Stable Lumen Output: Halogen cycle technology continuously prevents internal envelope blackening, providing steady brightness over time.
• Accurate Filament Alignment: Strong bi-pin base engineering maintains strict geometry relative to reflectors and condenser lenses.
