OSRAM XENOPHOT HLX | 400W EVD | 36V G6.35 Xenon Halogen

The Osram 64663 HLX (EVD) is a professional-grade, high-intensity Xenophot halogen lamp engineered for precision optical systems. By substituting xenon for standard krypton gas, Osram’s HLX technology delivers up to 10% higher luminous efficacy, producing a massive 16,200 lumens from a compact T6 capsule. This 400W, 36V lamp is the industry standard for overhead projectors, medical fiber optic illuminators, and studio lighting where absolute color fidelity (100 CRI) and exact filament positioning are non-negotiable. Manufactured in Germany, it features a specialized C-BAR-6 filament design for consistent, high-performance light output in critical scientific and diagnostic equipment.

Product Overview

The Osram 64663 HLX (EVD) is distinguished by its Xenophot technology, which allows the filament to operate at higher temperatures with greater efficiency and nearly constant luminous flux throughout its life. With a 3250K color temperature, it provides a brilliant warm white light that is essential for accurate microfilm reading and surgical site visualization. The 36mm Light Center Length (LCL) is precision-calibrated to ensure the filament sits at the exact focal point of optical lenses, preventing image distortion. Designed for professional use, this lamp is fully dimmable and reaches its full brightness instantly, supporting the demanding requirements of medical, studio, and laboratory environments.

• HLX Technology: Xenon gas fill provides up to 10% more light than standard halogen bulbs.
• Optical Precision: Manufacturing tolerances ensure perfect filament alignment for OHP and projectors.
