Medical Halogen Lamp

The Ushio SM-H2000 is a 50 watt halogen lamp operating at 22.8 volts with a G6.35 base. It produces 1000 lumens at a 3000K colour temperature for medical and scientific equipment. The lamp carries ANSI code SM-H2000 and is rated for an average life of 700 hours. It serves as a direct replacement for specific clinical devices.

Thermal and Power Characteristics

During normal operation the lamp draws 50 watts at its rated 22.8 volt supply. As a halogen source it generates noticeable heat and should be used only in fixtures designed for this wattage and voltage. The 3000K output indicates a warm white spectrum typical of halogen technology. No active cooling or noise is produced by the lamp itself.

Build and Compatibility

The compact G6.35 bi-pin base allows installation in compatible sockets without tools. Cross-reference numbers include OSRAM 54056 64650 and Ushio 8000325 for straightforward identification. Verified equipment fits include Dr. Mach M3F and Hanalux Siemens models 15282, 561 152 82 and H2000. Buyers needing a different base type, voltage or wattage should select an alternative lamp.

Questions about this item

How do I install the G6.35 base into the Dr. Mach M3F fixture correctly?

Switch off the device and let it cool. Align the two pins of the G6.35 base with the socket holes, then push straight in until the lamp seats firmly. The step often missed is handling the quartz envelope only with a clean cloth or gloves — skin oils create hot spots that shorten the 700-hour rated life.

When will this 50W 22.8V halogen lamp need replacement?

The average rated life is 700 hours. In a surgical or scientific fixture running continuously, expect to replace it roughly every four weeks; with intermittent use it will last proportionally longer. Light output will gradually decline as the filament ages.

What limit appears first during a long procedure with the SM-H2000?

The 700-hour filament life is the primary limit. Extended runs accelerate tungsten evaporation and envelope blackening, so output drops below the 1000-lumen spec before any thermal protection would activate.
