Title: Need help identifying buld
Post by: mhonings on July 26, 2020, 02:48:53 pm

Found this in an old barn, looking for any information I can get on it. I can't find any marking.

Looks like a relatively high power carbon filament bulb. Known as a "concentrating filament" type.
Viewed from the correct angle, the filament appears to occupy a relatively small area.
