Read these five fields before ordering
Use the old bulb and fixture label together. A shared base or wattage figure answers only part of the fit question.
- 01
Socket and shape
Match GU5.3 exactly. The MR16 code describes the bulb envelope, not the socket. Open the GU5.3 base guide. Check the MR16 shape profile.
- 02
Electrical rating
The source lists 12 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 180 lumens. The 20 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 1.81 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; it is marked dimmable; a wet/damp rating is not stated.

GU5.3 · Straight bi-pin reflector base
GU5.3 uses two straight pins spaced a nominal 5.3 mm apart. It is commonly paired with MR16 reflectors but does not itself define voltage or beam angle.

Questions about 0474900
What socket does Westinghouse 0474900 use?
Westinghouse lists this model with a GU5.3 base. Look for the same complete base code on the socket or old lamp. The MR16 shape is a separate specification.
Is Westinghouse 0474900 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Westinghouse 0474900 be used in an enclosed fixture?
The source snapshot does not state an enclosed-fixture rating. Do not infer one from shape or wattage; confirm on the bulb or manufacturer page.
