OSRAM 64617 M117 - MR11 75W 12V Dichroic Halogen Lamp (XENOPHOT HLX)

OSRAM 64617 M117 - MR11 75W 12V Dichroic Halogen Lamp (XENOPHOT HLX)

The Osram 64617 M117 is a 75W , 12V halogen lamp with an MR11 reflector, a G5.3 (G5.3-4.8) base, and a dichroic coating. It belongs to the XENOPHOT HLX family, which uses xenon gas instead of krypton and offers up to 10% more luminous flux with the same energy consumption compared to standard halogen lamps. It is designed for demanding professional applications such as microscopy, laboratory and analytical work, UV curing, fiber optic illumination, and surgical and dental equipment, where accurate color rendering (CRI 100) , a color temperature of 3200K , instant start-up, and stable performance throughout its lifespan are required.

Its optics are optimized with precise alignment of the filament and reflector (quartz clamp technology), improving beam concentration at the 26 mm focal length . The 35 mm diameter MR11 reflector and overall length of 35.5 mm facilitate direct integration into medical and laboratory light sources using a G5.3 socket. It is dimmable , accepts alternating current (AC) , and, due to its high power density, requires forced cooling and use in suitable luminaires. The rated life is 25 hours , consistent with its high-performance design.

• Flawless color reproduction (CRI 100): ideal for visual diagnostics and processes where color is critical.
• Wide compatibility: G5.3 socket and standard MR11 format for multiple medical, dental, and laboratory equipment.
• Stable and repeatable beam: precise alignment of filament and reflector for consistent uniformity and focus.
• Total intensity control: adjustable operation to adjust the lighting to the procedure.

Use cases

• Microscopy and fiber optic illumination in laboratories and analysis.
• Dentistry and surgery (overhead lighting and auxiliary light sources).
• UV curing processes and precision tasks in industry and science.

Frequently Asked Questions

• What is the difference between the standard 64617 and the 64617 HLX? The HLX uses xenon gas and provides up to 10% more luminous flux with the same energy consumption.
