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 E39 exactly. The T30 code describes the bulb envelope, not the socket. Compare base profiles.
- 02
Electrical rating
The source lists 120/277 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 7,020 lumens. The 54 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 10.24 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
The source approves totally enclosed fixtures; dimming is not stated; the location rating is Damp.

Questions about 3516600
What socket does Westinghouse 3516600 use?
The official record identifies a E39 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 3516600 dimmable?
The source snapshot does not state a dimming rating. Treat dimmer compatibility as unconfirmed.
Can Westinghouse 3516600 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.
