OSRAM HBO 103 W/2 - 103 W Mercury Short Arc Lamp for Microscopy and UV Curing

OSRAM HBO 103 W/2 - 103 W Mercury Short Arc Lamp for Microscopy and UV Curing

The OSRAM HBO 103 W/2 is a 103 W DC mercury short-arc lamp designed to deliver extremely high luminance and powerful radiation in the UV and visible ranges . Its multilinear spectrum and arc stability make it an ideal source for fluorescence microscopy , UV curing , and fiber optic illumination . It provides a nominal luminous flux of 2,550 lm and an intensity of 300 cd , with an efficacy of 30 lm/W . The compact geometry (Ø 10 mm , 90 mm length, LCL 43 mm ) and the SFa9-2 (anode) / SFa7.5-2 (cathode) bases facilitate its integration into laboratory lamphouses and scientific imaging systems. It has a nominal lifespan of 300 h and an S90 burn-in position (anode down) for stable performance.

Frequently Asked Questions

Does it work on AC? No. This lamp is designed for direct current (DC) .

How should I handle it? Wear gloves and goggles; do not touch the bulb. Let it cool before removing it.

Is UV radiation dangerous? Yes. It must be operated exclusively in specific enclosed housings , following the equipment manual.

What is the correct position? s90 , with the anode facing down, unless otherwise indicated by the equipment manufacturer.

Security and compliance

• Mandatory operation in closed housings due to high luminance, UV radiation and hot internal pressure.
• Contains mercury ; if broken, vapors may be released. Follow the manufacturer's safety procedures and local regulations.
• End-of-life management of discharge lamp waste .

Logistics data (individual unit)

• Packaging dimensions: 165 × 95 × 48 mm
• Packaging volume: 0.75 dm³
• Gross weight (including packaging): 91 g
