Osram 64634 Xenophot 150W 15V EFR Halogen MR16 Lamp – ANSI EFR | GZ6.35 Bipin | 32mm Focal Length

The Osram 64634 Xenophot EFR is a 150-watt 15-volt MR16 open-face halogen lamp designed for display, projection, dental, and optical lighting equipment requiring ANSI EFR specifications. Featuring a GZ6.35 bipin base, 32mm focal length, and Xenophot® xenon gas technology, this lamp provides high luminous intensity and consistent photometric performance for professional optical systems.

Product Overview

The Osram Xenophot 64634 halogen lamp is engineered for precision optical applications including medical lighting systems, dental equipment, projection systems, and laboratory instruments. Operating at 150 watts and 15 volts, the lamp delivers high intensity illumination through an MR16 open-face dichroic reflector.

Xenophot® technology uses xenon gas instead of krypton inside the quartz envelope, producing up to 10% higher luminous output while maintaining identical electrical characteristics. This improves brightness and efficiency without changing system specifications.
