OSRAM 64653 HLX (ELC) - MR16 250 W 24 V Halogen Lamp with Dichroic Reflector (50 h)

OSRAM 64653 HLX (ELC) - MR16 250 W 24 V Halogen Lamp with Dichroic Reflector (50 h)

The OSRAM 64653 HLX is a professional 250W, 24V halogen lamp in an MR16 format with a GX5.3 base and dichroic reflector. It belongs to the XENOPHOT HLX family, which uses xenon gas to provide up to 10% more luminous flux compared to standard halogen lamps with the same power consumption, while maintaining a CRI of 100 and a color temperature of 3400K . Its compact optics and precise filament alignment within the reflector provide a highly controlled beam, ideal for microscopy , laboratory analysis , fiber optic illumination , UV curing , and dental/surgical lighting . The dichroic coating promotes a "cool beam," transferring some of the heat to the back of the reflector to protect the illuminated object. It has a nominal lifespan of 50 hours and requires forced cooling for continuous operation.

Main features

• Cooling: forced (mandatory in continuous use).
• Adjustable: Yes, with suitable equipment.
• Identification: ANSI ELC , LIF A1/259 .
• Weight: 28.7 g.
• Packaging: individual unit; shipping box of 20 units .
• Siluj Code: 003-0709.

Product benefits

• More light with the same power: XENOPHOT HLX technology with up to a 10% increase in flux compared to standard halogens, while maintaining dimensions and connection.
• True and consistent color: CRI 100 and instant start, with virtually constant flow throughout its lifespan.
• Cool light: the dichroic reflector reflects visible light and lets some infrared light pass through to the back, reducing the heating of the illuminated surface.
• Precise integration: 35mm LCL and 51mm MR16 for optimal alignment in projection, microscopy, and fiber optic systems.
• Easy maintenance: halogen capsule and quick-insertion GX5.3 base.

Use cases

• Microscopy and laboratory: homogeneous illumination in Köhler systems, photometry and stereomicroscopes.
• Optical fiber: concentrated beam illuminators for inspection and machine vision.
• Curing and photochemistry: UV curing equipment that uses halogens with reflector.
• Dental/surgical: overhead lamps and auxiliary equipment compliant with ANSI ELC / LIF A1/259.
• Projection and effects: projectors and entertainment luminaires that require MR16 24 V 250 W.

Frequently Asked Questions

Is this lamp equivalent to other 24V/250W ELC lamps?
Yes, the ANSI ELC and LIF A1/259 designations ensure compatibility. However, please verify the LCL 35 mm , GX5.3 base, and the need for forced cooling in your system.

Are there longer lifespan variants (ELC/5, ELC/10)?
Yes, there are variants with different rated lifespans and outputs. If your priority is lifespan rather than maximum performance, you might consider the ELC/5 or ELC/10; always check the equipment manufacturer's specifications.

Can I use it without ventilation?
Not recommended. This product requires forced cooling to maintain performance and lifespan.

Which transformer do I need?
One suitable for 24 V AC and with sufficient power for 250 W, compatible with halogen loads and, if applicable, with regulation.

Installation and best practices

• Check the compatibility of the GX5.3 lamp holder and the 24V voltage .
• Install in halogen-compatible light fixtures and respect thermal/UV warnings.
• Do not touch the quartz capsule with your fingers; use gloves or a clean cloth.
• Ensure active ventilation according to the equipment's instructions.
