What fixtures commonly use it
Chandeliers, decorative sconces, nightlights, and ceiling fan light kits in North America commonly use E12 candelabra sockets.
What it's interchangeable with
E12 and E14 share the same general candelabra profile but differ by 2mm in diameter. An E14 bulb will not reliably thread into an E12 socket.
What it's NOT interchangeable with
E12 does not fit E26 or E27 standard sockets due to the large size difference.
