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 E26 exactly. The A15 code describes the bulb envelope, not the socket. Open the E26 base guide.
- 02
Electrical rating
The source lists 130 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 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 0450300
What socket does Westinghouse 0450300 use?
The official record identifies a E26 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 0450300 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 0450300 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.
