Specialised Halogen Lamp for Scientific Use

The Ushio SM-50067 is a 100W halogen bulb operating at 23V with an X514 base. It delivers a 3250K colour temperature and a 99 CRI for accurate colour rendering in medical and scientific instruments. The lamp produces 3000 lumens and has an average rated life of 300 hours.

Replaces Worn Lamps in Precision Equipment

This bulb serves as a direct replacement when the original lamp in a compatible device reaches the end of its 300-hour rated life. The upgrade is worth it when colour fidelity is critical and the existing lamp has dimmed or shifted colour temperature. It restores the specified 3000-lumen output and 99 CRI performance.

Limited by Short Life and Fixed Voltage

The 300-hour lifespan means frequent replacement cycles in continuous-use applications. The fixed 23V requirement restricts use to equipment designed for this specific voltage. The X514 base prevents installation in standard sockets. Buyers needing longer intervals between changes or different voltage compatibility cannot use this lamp.

Questions about this item

What socket does the X514 base on this Ushio SM-50067 halogen bulb fit?

The X514 base is a specialised bipin connector used in scientific and medical equipment; it mates only with a matching X514 socket rated for 23 V operation.

What is the critical step when installing this 100 W halogen lamp to avoid early failure?

Handle the quartz envelope only with clean, lint-free gloves; skin oils create hot spots that shorten the 300-hour rated life.

How often should I plan to replace this bulb given its 300-hour average rated life?

At 300 hours average rated life, schedule replacement after roughly 300 hours of use; the 3250 K colour temperature and 99 CRI will remain stable until end of life.
