In my kitchen, ceiling fixture. 2 incandescent bulbs.
I switched both bulbs to a don't recall manufacture LED's.
For no rhyme or reason I can figure, on occasion,
when I turn the light off,
one of the bulbs glow for about 5 or so seconds before going completely dark.

Electrical problem or cheap LED's?

Thanks....notnew....

I do not have the explanation, but have had the same experience with shop light style fixtures, name brand Feit. No issues with function in any regard, FYI.

I would change the bulb just to study the results in detail.

The LEDs in the bulb don't operate at 120 volts. There is circuitry in the base to turn the 120 volts AC into the DC voltage required for the LED. Within that circuitry there are capacitors that hold a charge after power has been turned off. As the LED discharges the capacitor you get a small glow.

Yes that is detailed in most directions that come with bulbs.

Sometimes LED bulbs can have flicker issues. That slow fade to black helps get rid of the flicker.
