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 G9 exactly. The G9 code describes the bulb envelope, not the socket. Open the G9 base guide.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 500 lumens. The 5 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 2.13 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 Damp.

G9 · Looped bi-pin
G9 uses two wire loops rather than straight pins. The lamp pushes into the socket and is common in compact decorative fixtures.

Questions about 5164100
What socket does Westinghouse 5164100 use?
The official record identifies a G9 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 5164100 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 5164100 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.
