Before replacing it

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.

  1. 01

    Socket

    Match G13 exactly. The T8 code describes the bulb envelope, not the socket. Compare base profiles.

  2. 02

    Electrical rating

    The source lists 120/277 V. Confirm that against the fixture and local supply.

  3. 03

    Brightness, not “watts”

    Target about 1,800 lumens. The 14 W figure is input power, not brightness.

  4. 04

    Physical clearance

    The official maximum overall length is 48 inches. Check shade, cover, and neck clearance.

  5. 05

    Heat, controls, and location

    The source approves totally enclosed fixtures; it is marked dimmable; the location rating is Damp.

Quick answers

Questions about 5156100

What socket does Westinghouse 5156100 use?

The official record identifies a G13 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.

Is Westinghouse 5156100 dimmable?

Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.

Can Westinghouse 5156100 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.
