Equipment compatibility

Dental curing equipment references

Ushio identifies 1000921 as JCR/M12V-100W and cross-references it to OSRAM 64624. This is a 12V, 100W MR11 reflector halogen lamp. The equipment references below are documented in Bulbworks' dental lamp cross-reference catalog for the JCRM12V-100W / 64624 lamp family.

Equipment Required version / original lamp reference
Demetron 400, 401 and 403 High Output 12V, 100W version; original lamp reference 20140
Den-Mat Ceri Light Original lamp reference 3961; 12V, 100W
L.D. Caulk / Dentsply Prismetics Lite Original lamp reference 644358; 12V, 100W
Kinetic Instruments Sunspot Original lamp reference 1511; 12V, 100W
Kulzer Translux CL Original lamp reference 2244; 12V, 100W

Check the exact version before ordering. Demetron models also appear with 75W or 80W lamps; the High Output reference above does not cover those versions. Translux EC, EC-S and II use a different 15V, 150W lamp. Do not select this lamp by the equipment family name or socket fit alone.

For any dental curing machine, match its service-manual lamp specification and original lamp markings, including reflector, filament, dimensions and electrical rating. These references do not establish compatibility with an unidentified machine or verify its curing output. Send the equipment make/model and original lamp markings if you need a fit check.

Sources: Ushio lamp catalog (printed pages 11 and 38); Bulbworks 2026 dental lamp cross-reference catalog (printed pages 4, 6 and 10). Equipment references are supplier-documented; the current equipment manual and exact lamp specification take precedence.

Confirm any substitute against the complete electrical, mechanical, optical, filament, dimensional, and operating specification. A shared ANSI code may identify a lamp family but does not override equipment requirements.

Documentation & safety

Manufacturer documentation and handling

Halogen safety: Disconnect power and allow the equipment to cool before service. Install only in approved enclosed equipment with the required protective screen, ventilation, electrical controls, and shielding. Handle quartz with clean gloves or lint-free tissue and avoid touching the envelope with bare skin.
