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

    Voltage is not stated in this snapshot. Read it from the lamp or official record before substituting.

  3. 03

    Brightness, not “watts”

    Target about 1,000 lumens. The 12 W figure is input power, not brightness.

  4. 04

    Physical clearance

    Confirm that the T8 envelope fits the shade or cover; this snapshot does not provide complete dimensions.

  5. 05

    Heat, controls, and location

    Enclosed-fixture use is not stated; it is marked non-dimmable; the location rating is Damp.

Quick answers

Questions about T818/840/LED

What socket does Feit Electric T818/840/LED 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 Feit Electric T818/840/LED dimmable?

No. The official record marks this model as non-dimmable, so it should not be used on a dimming circuit.

Can Feit Electric T818/840/LED 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.
