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 T38 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 15,000 lumens. The 100 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 11.1 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 4516700
What socket does Westinghouse 4516700 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 4516700 dimmable?
The source snapshot does not state a dimming rating. Treat dimmer compatibility as unconfirmed.
Can Westinghouse 4516700 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.
