Five checks decide the fit
A shared base or wattage alone is not enough. Work down the list with the old bulb and fixture label in hand.
- 01
Socket
Match E12 exactly. The C7 code describes the bulb envelope, not the socket. Open the E12 base guide.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 90 lumens. The 15 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 2.11 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; dimming is not stated; a wet/damp rating is not stated.

Questions about 3720800
What socket does Westinghouse 3720800 use?
The official record identifies a E12 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 3720800 dimmable?
The source snapshot does not state a dimming rating. Treat dimmer compatibility as unconfirmed.
Can Westinghouse 3720800 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.
