OSRAM 64665 HLX - 36V 400W G6.35 Bipin Halogen Lamp (XENOPHOT) for Scientific and Medical Equipment

OSRAM 64665 HLX - 36V 400W G6.35 Bipin Halogen Lamp (XENOPHOT) for Scientific and Medical Equipment

The OSRAM 64665 HLX is a low-voltage, bipin G6.35 halogen lamp designed to deliver intense and uniform light in demanding professional applications. Part of the XENOPHOT HLX series, it uses xenon gas as a filler to provide up to 10% more luminous flux with the same power consumption compared to standard halogen lamps. Operating at 36 V and 400 W , it delivers a nominal flux of 12,200 lm with a color temperature of 3400 K , offering instant start, dimming , and virtually constant flux throughout its 300-hour lifespan. Its 36 mm LCL (Light Center Length) , precise filament alignment , and 10.5 × 5.3 mm² illuminated field ensure a controlled and stable beam in fiber optic systems, microscopy, UV curing, analysis, and medical/laboratory lighting. Compact dimensions ( 60 mm long and 18 mm in diameter) and s90 burn position for reliable integration into compatible equipment.

Main features

• XENOPHOT HLX technology: xenon gas instead of krypton for greater luminous performance with the same consumption.
• Power and voltage: 400 W, 36 V.
• Base: G6.35 (bipin) for firm mounting and reliable electrical contact.
• Flux and color: 12,200 lm nominal; 3400 K for neutral warm white light, suitable for imaging and analysis.
• Useful life: 300 h nominal.
• Adjustable: compatible with intensity control suitable for 36V halogen charging.
• Optical geometry: LCL 36 mm , illuminated field 10.5 × 5.3 mm² and filament length ~10.5 mm for precise focusing.
• Dimensions: length 60 mm, diameter 18 mm; weight approx. 12 g.
• Burning position: s90 .
• LIF Classification: A1/166 .
• Design advantages: precise filament alignment (patented quartz clamp), instant ignition, and stable flux throughout the lamp's life.

Product benefits

• More light without increasing consumption: the HLX version increases the flux by up to 10%, useful in tasks where beam intensity and uniformity are critical.
• Natural color rendering: typical halogen continuous spectrum, suitable for observation and documentation.
• Control and stability: smooth regulation and virtually constant flow for repeatable results in laboratory and clinical settings.
• Easy integration: Standardized dimensions and LCL for direct replacement in G6.35, 36V/400W compatible equipment.

Use cases

• Microscopy and analysis: homogeneous illumination for observation, inspection and documentation.
• Medical and scientific optical fiber: light sources for light guides in endoscopy, field illumination and inspection systems.
• UV curing and photo-optics: laboratory equipment and optical benches designed for 36V halogen lamps.
• Special lighting fixtures in healthcare environments: procedure lamps, operating rooms and dental units that specify A1/166.

Frequently Asked Questions

• Is it dimmable? Yes. Use a regulator/driver compatible with 36V halogen loads to preserve service life and flux stability.
• What are the LIF and ANSI codes? LIF: A1/166 . This model does not have an ANSI code assigned by OSRAM. The ANSI EVD code corresponds to reference 64663 HLX , not 64665.
• What working position does it support? Position s90 , according to the manufacturer's specification.
• Can I touch the bulb with my hands? Avoid doing so. Handle it with gloves or a clean cloth to prevent leaving residue that could shorten the lamp's lifespan.
• Safety requirements? Operate only on suitable luminaires/equipment protected against UV radiation and fragment projection; respect ventilation and heat dissipation of the equipment.

Installation and safety notes

• Disconnect the equipment and allow it to cool before replacing the lamp.
• Check compatibility: 36V, 400W, G6.35 base, LCL 36mm and s90 burn position.
• Do not use in open luminaires without the protective elements indicated by the equipment manufacturer.
