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 E26 exactly. The ST19 code describes the bulb envelope, not the socket. Open the E26 base guide.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 180 lumens. The 5 W figure is input power, not brightness.
- 04
Physical clearance
Confirm that the ST19 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 dimmable; the location rating is Damp.

Questions about ST19/MOSAIC
What socket does Feit Electric ST19/MOSAIC use?
The official record identifies a E26 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Feit Electric ST19/MOSAIC dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Feit Electric ST19/MOSAIC 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.
