I bought some of the LED replacements for Edison bulb incandescents, and
they have an afterglow that lasts for several minutes. It is very much
dimmer than when they are turned on, but is there none the less.

The speed isn't terribly surprising since the "phosphor" used is

Unlike phosphors scintillators don't have long decay times so there is
no afterglow like that from a phosphor.
The IKEA LED lamp output may not be significantly modulated if the wall
wart constant current supply may have an output thats a little smoother
than just rectified AC.
