OSRAM HBO 100 W/2 - Mercury Short Arc Lamp for Fluorescence Microscopy and UV Curing
The OSRAM HBO 100 W/2 is a 100 W mercury short-arc lamp designed to provide a point source of extremely high luminance and UV-Visible radiation . Its characteristic multilinear mercury spectrum allows it to efficiently excite a wide range of fluorochromes in fluorescence microscopy and provide stable energy for UV curing and light guide illumination . It offers a nominal luminous flux of 2,200 lm , an intensity of 260 cd , and an efficacy of 22 lm/W , with a compact geometry ( Ø 10 mm , MOL 90 mm , mounting length 82 mm ) and LCL 43 mm for optimal integration into cassettes and fluorescence lamps. It operates on direct current (DC) with a lamp voltage of 17–25 V and a current of 4.3–5.6 A , SFa9-2 (anode) and SFa7.5-2 (cathode) bases, s90 burn position (vertical, anode down) and a nominal lifespan of 200 h . It is ideal for laboratory and analytical applications , microscopy , UV curing , fiber optic illumination and solar simulation .

Exact compatibility depends on the lamp holder/cassette and the equipment manufacturer.
Frequently Asked Questions
-
Does it require a specific power supply? Yes, it requires a regulated DC power supply and a cassette/enclosed housing designed for 100W HBO lamps.
-
Can it be used in any orientation? No. The burning position is s90 (vertical, anode down) . Follow the manufacturer's instructions.
-
Is it suitable for time-lapse photography? Yes, its stable short arc produces continuous (unmodulated) light, ideal for scientific photography.
-
What maintenance does it require? Record hours of use and replace around 200 hours or when intensity/stability decreases.
Usage and safety recommendations
- Operate only in enclosed housings designed for HBO due to their high luminance, UV radiation and high internal hot pressure .
-
Do not look directly at the arc; use appropriate eye protection and filters .
- Contains mercury : manage in accordance with applicable regulations and the manufacturer's instructions.
