Purpose and fit

The Ushio SM-3800-18-2520 is a 60W 12V incandescent bulb with a BA20d base, rated for 100 hours average life and 1400 lumens. It suits medical, scientific or healthcare equipment that specifies this ANSI code and the C-6Z filament design.

Thermals, noise and power

As an incandescent lamp it draws a steady 60 watts at 12 volts and converts most of that energy into heat; the clear envelope and compact 63.5 mm length mean the fixture must tolerate the resulting temperature rise. No active cooling or fan is present, so operation is silent.

Included accessories and software

The bulb is supplied as a single replacement unit identified by product code 8000173 and part number BC8959; no additional adapters, drivers or software are bundled. Buyers needing a different base type, longer life or lower heat output will need an alternative lamp design.

Questions about this item

How do I install the BA20d base correctly, and what step do people often miss?

Align the pins on the BA20d base with the socket slots, push in, then twist clockwise until the ring locks; the step often missed is the final twist that secures the ring.

What maintenance or replacement will this 60W 12V incandescent bulb need after its 100-hour rated life?

The filament will burn out after roughly 100 hours of continuous use; simply replace the whole bulb — no separate components are serviceable.

What limit appears first when this C-6Z filament bulb runs continuously at 12V?

The 100-hour average rated life is the first limit; the tungsten filament will fail before heat or voltage stress becomes an issue.
