OSRAM HBO 200 W/DC TM — Reflectorless Short Arc Mercury Lamp for Microscopy, UV Curing and Light Guides

OSRAM HBO 200 W/DC TM — Reflectorless Short Arc Mercury Lamp for Microscopy, UV Curing and Light Guides

The OSRAM HBO 200 W/DC TM is a short-arc mercury discharge lamp (double-ended, reflectorless) designed for fluorescence microscopy , UV curing , and light-guiding applications in laboratories and scientific equipment. It provides a very high luminance point source with a multilinear spectrum and high radiant power in both the UV and visible ranges , offering 9,500 lm of luminous flux and 1,000 cd of typical intensity. It operates on direct current (DC) at 200 W , 57–65 V , and 3.0–4.3 A , and has a rated life of 400 h .

Its compact and precise design— LCL 40 mm , diameter 17 mm , total length 125 mm , mounting length 102 mm —with SFc10-4 anode and cathode bases allows for integration into microscope illuminators and fiber optic systems. The s90 firing position (anode down) contributes to arc stability and photometric repeatability in demanding instrumentation.

• Repeatability of color and intensity thanks to the stability of the arc and the specified working position.
• Professional integration into OEM illuminators and UV microscopy and curing equipment.

Use cases

• Fluorescence microscopy in biomedical research and quality control.
• UV curing in dental, cosmetic and industrial processes.
• Light guides for precision illumination in medical and scientific devices.
• Solar simulation / analysis when a broad spectrum with characteristic mercury peaks is required.

Frequently Asked Questions

Does it require a special ballast or power supply? Yes. It must operate with a specific DC power supply and the ignition equipment specified by the instrument manufacturer.

Can it be dimmed with a conventional dimmer? No. It is not dimmable using standard dimmers; any control must be done with the power supply specified by the OEM.

Can I mount it in any orientation? The s90 position (anode down) is specified for rated performance and lifespan.

Is it suitable for domestic use? No. It is a special-purpose lamp for enclosed laboratory and industrial equipment.

Safety and handling

• Operate only in enclosed housings designed for HBO due to high luminance, UV radiation and high internal hot pressure .
• Contains mercury : follow local waste regulations and the manufacturer's instructions in case of breakage.
• Respect polarity, ventilation and thermal limits of the equipment; handle with clean gloves.

Compatibility and installation

• Check 200W , 57–65V DC , SFc10-4 on both poles and LCL 40mm on your illuminator.
• Reference lengths for integration: 125 mm (total length) and 102 mm (mounting length).
• Align s90 (anode down) as specified by OSRAM.
