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 4-Pin exactly. The T9 code describes the bulb envelope, not the socket. Compare base profiles.
- 02
Electrical rating
Voltage is not stated in this snapshot. Read it from the lamp or official record before substituting.
- 03
Brightness, not “watts”
Target about 1,550 lumens. The 30 W figure is input power, not brightness.
- 04
Physical clearance
Confirm that the T9 envelope fits the shade or cover; this snapshot does not provide complete dimensions.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; it is marked non-dimmable; the location rating is Indoor/Outdoor.

Questions about FC30/CW
What socket does Feit Electric FC30/CW use?
The official record identifies a 4-Pin base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Feit Electric FC30/CW dimmable?
No. The official record marks this model as non-dimmable, so it should not be used on a dimming circuit.
Can Feit Electric FC30/CW 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.
