OK, I never thought I would ask about light bulbs. I had a bulb go out in the bathroom. The lamp says 18v type 921. Searching online at large stores, the closest I get is a T5. Is this a match? Pic of the lightbulb and light fixture.
 
It's a t10
The 18v is maximum voltage.
They run on 7ish volts to 18v.

Posting a picture would help others(and myself in case memory is memory memorying wrong.)
 
Dang it. I thought I had attached the pics.

I've posted it before in my signature thread, but my factory thor backups were under 600lumen.
My led replacements are under 6000 lumens. (Phone app measured using same phone and distance)
