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 A19 code describes the bulb envelope, not the socket. Open the E26 base guide.
- 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 1,600 lumens. The 15 W figure is input power, not brightness.
- 04
Physical clearance
Confirm that the A19 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; a wet/damp rating is not stated.

Questions about 42274
What socket does SYLVANIA 42274 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 SYLVANIA 42274 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can SYLVANIA 42274 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.
