Read these five fields before ordering
Use the old bulb and fixture label together. A shared base or wattage figure answers only part of the fit question.
- 01
Socket and shape
Match E26 exactly. The A19 code describes the bulb envelope, not the socket. Open the E26 base guide. Check the A19 shape profile.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 450 lumens. The 5 W figure is input power, not brightness.
- 04
Physical clearance
Confirm that the A19 envelope fits the shade or cover; this snapshot does not provide complete dimensions.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; it is marked dimmable; the location rating is Damp.

Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
