OSRAM BTR | 54689 | 1000W 120V Halogen Display Optic Lamp

The Osram Sylvania BTR (54689) is a high-performance 1000-watt halogen lamp designed for precision optical systems in theater, film, and high-end display environments. Engineered with a P28s Medium Prefocus base, this lamp ensures critical filament alignment for accurate light distribution. It delivers a powerful 3200K warm white light with a perfect CRI of 100, making it indispensable for museum exhibits, retail showrooms, and professional studio sets where true-to-life color rendering is non-negotiable. The C-13D filament configuration is built for stability and high-output performance across its 500-hour rated life.

Professional Optical Precision

The ANSI BTR lamp is recognized for its exceptional light quality and precise mechanical construction. The prefocus base eliminates the need for manual adjustment, seating the T7 tubular bulb in the exact focal point of your fixture's reflector. This results in a highly controlled beam pattern ideal for Fresnel spotlights and specialized retail display housings. As a clear halogen source, it maintains its 3200K color temperature throughout the life of the lamp, ensuring that your lighting design remains consistent from the first hour to the last.

• Clear Display Optic: Transparent quartz envelope for maximum light transmission and sharp distribution.
• Superior CRI: 100 CRI ensures that artifacts, merchandise, and skin tones are rendered with total accuracy.
• High-Temperature Durability: Engineered to withstand the extreme thermal loads of 1000W operation in enclosed professional fixtures.
• Stable Filament: C-13D coil design resists vibration and maintains lumen output stability.
