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 GU5.3 exactly. The MR16 code describes the bulb envelope, not the socket. Compare base profiles.
- 02
Electrical rating
The source lists 12 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 360 lumens. The 4.5 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 1.85 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.

Questions about 3363800
What socket does Westinghouse 3363800 use?
The official record identifies a GU5.3 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Westinghouse 3363800 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 3363800 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.
