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 A15 code describes the bulb envelope, not the socket. Open the E26 base guide. Check the A15 shape profile.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 340 lumens. The 40 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 3.38 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; it is marked dimmable; a wet/damp rating is not stated.

Questions about 0393000
What socket does Westinghouse 0393000 use?

Is Westinghouse 0393000 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 0393000 be used in an enclosed fixture?
The source snapshot does not state an enclosed-fixture rating. Do not infer one from shape or wattage; confirm on the bulb or manufacturer page.
