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 E26 base. The base code does not guarantee the bulb width, length, beam angle, or clearance.
Before you buy a replacement
- E26 and E27 are close in size but belong to different voltage systems.
- Confirm enclosed-fixture and dimmer ratings before switching to LED.
- Match bulb shape and clearance as well as the base.
