OSRAM HLX 64634 - Dichroic lamp MR16 15V/150W (XENOPHOT, 50 h)

OSRAM HLX 64634 - Dichroic lamp MR16 15V/150W (XENOPHOT, 50 h)

The OSRAM HLX 64634 is a halogen lamp with an MR16 dichroic reflector , designed for medical, scientific, and industrial applications, as well as entertainment lighting equipment requiring a precise beam and high light stability. It belongs to the XENOPHOT HLX family, which uses xenon instead of krypton as a fill gas to provide up to 10% more luminous flux with the same energy consumption compared to standard halogen lamps. With a power rating of 150 W at 15 V , a GZ6.35 base , a focal length of 32 mm , and a maximum color temperature of 3200 K , it offers reliable and repeatable performance in fiber optic equipment, microscopes, endoscopic light sources, UV curing, and 150 W scanner/gobo lights.

Its dichroic (cold mirror) coating improves thermal management by reflecting visible light forward and dissipating infrared radiation to the rear, while the P90/P15 burn-in position and forced cooling requirement ensure safe and stable operation. The lamp is dimmable and internationally categorized as ANSI EFR and LIF A1/232 , facilitating its identification and compatibility with a wide range of professional equipment. Typical lifespan: 50 hours .

Main features

• XENOPHOT HLX technology : xenon as a fill gas for up to +10% luminous flux with the same consumption.
• Precise optics : MR16 dichroic reflector with a 32mm focal length for a stable and defined beam.
• Key specifications : 15 V, 150 W, GZ6.35 , diameter 51.0 mm , length 42.0 mm , lifespan 50 h , Tc max. 3200 K.
• Safe operation : requires forced cooling and supports p90/p15 burn position .
• Standardized compatibility : ANSI EFR and LIF A1/232 codes; ideal for equipment specifying “EFR 15 V / 150 W”.
• Adjustable : supports dimming to adjust the intensity according to the application.

Product benefits

• More light without increasing consumption : the gas mixture with xenon in the HLX series improves light output while maintaining efficiency.
• Color and stability : typical halogen continuous spectrum with Tc max. 3200 K, suitable for visual inspection and faithful color reproduction.
• Easy integration : the GZ6.35 base and the EFR/A1/232 codes facilitate replacement in numerous light sources and luminaires.
• Optimized thermal management : the dichroic coating directs heat to the rear, protecting the beam and front optical components.
• Consistent performance : Precise alignment of filament and reflector promotes a consistent beam throughout its lifespan.

Use cases

• Medicine and laboratory : light sources for endoscopy, microscopy and fiber optic systems in the operating room or bench.
• Science and industry : spot lighting for analysis, inspection, UV curing and technical tasks.
• Entertainment and events : 150W scanners/gobos and lighting effects that specify lamp: EFR 15V 150W .

Compatibilities and equivalencies (EFR reference)

This lamp replaces other EFR MR16 15V/150W lamps with a GZ6.35 base from various manufacturers, provided the equipment specifically requires “EFR 15V 150W MR16 GZ6.35”. In professional lighting, some older fixtures use this lamp type (e.g., certain American DJ scanners ). In the medical/scientific field, it is common in microscopy and endoscopy light sources. Always consult the equipment manual before replacing the lamp.

Installation and safety

• Check voltage and base of the lamp holder (GZ6.35) and the 32 mm focal length required by the equipment.
• Respect the indicated p90/p15 burn position and ensure a continuous forced airflow during operation.
• Do not touch the bulb/reflector with your hands; use gloves or a lint-free cloth.
• Use the lamp in enclosed luminaires and housings approved by the equipment manufacturer.
