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 GU24 exactly. The A21 code describes the bulb envelope, not the socket. Open the GU24 base guide.
- 02
Electrical rating
The source lists 120 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 1,600 lumens. The 16 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; it is marked dimmable; the location rating is Damp.

Questions about 558684
What socket does Philips 558684 use?
The official record identifies a GU24 base. The replacement socket must use the same base code; a similar-looking bulb shape does not establish socket compatibility.
Is Philips 558684 dimmable?
Yes. The official record marks this model as dimmable, but the installed dimmer must also support the lamp technology and load.
Can Philips 558684 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.
