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 G8 exactly. The T4 code describes the bulb envelope, not the socket. Compare base profiles.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 175 lumens. The 20 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 1.38 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 0621000
What socket does Westinghouse 0621000 use?
The official record identifies a G8 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 0621000 dimmable?
The source snapshot does not state a dimming rating. Treat dimmer compatibility as unconfirmed.
Can Westinghouse 0621000 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.
