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 A21 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 2,610 lumens. The 29 W figure is input power, not brightness.
- 04
Physical clearance
Confirm that the A21 envelope fits the shade or cover; this snapshot does not provide complete dimensions.
- 05
Heat, controls, and location
Enclosed-fixture use is not stated; dimming is not stated; the location rating is Damp.

Questions about 571497
What socket does Philips 571497 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 Philips 571497 dimmable?
The source snapshot does not state a dimming rating. Treat dimmer compatibility as unconfirmed.
Can Philips 571497 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.
