How to identify E14
- Look for E14 on the bulb, holder, packaging, or fixture label.
- Measure straight across the widest part of the threaded metal base.
- Check voltage separately; E14 products exist for more than one supply system.
Where it is commonly used
Common use is a clue, not proof. The fixture label and model documentation take priority over a visual match.
Bulb shapes sold with this base
You may see these shapes with a E14 base. The base code does not guarantee the bulb width, length, beam angle, or clearance.
Before you buy a replacement
- E14 and E12 are different sizes and should not be forced or treated as interchangeable.
- Imported fixtures require a voltage and local-approval check as well as a base match.
- Measure the bulb envelope and overall length inside compact shades and covers.
