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 ST20 code describes the bulb envelope, not the socket. Open the E26 base guide.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 1,100 lumens. The 10 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 5.43 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
The source approves totally enclosed fixtures; it is marked dimmable; the location rating is Wet.

Questions about 5287000
What socket does Westinghouse 5287000 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 5287000 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 5287000 be used in an enclosed fixture?
The official record marks it for totally enclosed fixtures. The fixture's wattage, voltage, and clearance limits still apply.
