What fixtures commonly use it
European chandeliers, decorative bedside lamps, refrigerator bulbs, and small accent fixtures typically use E14 sockets.
What it's interchangeable with
E14 and E12 are functionally similar in role but not physically interchangeable — 2mm diameter difference means thread engagement is unreliable between the two.
What it's NOT interchangeable with
E14 does not fit E27 or E26 standard sockets, and bayonet B22 is a completely different system.
Common mistakes
- Purchasing E12 bulbs for European E14 fixtures.
- Importing appliances and not checking whether E14 bulbs are available locally.
