I have a LED bulb that for some reason faintly "afterglows" for hours after I turn off the light. The glow quickly fades when I screw the bulb out of its socket, and comes back when I screw it back in (the light switch is off the entire time!) ... such unintuitive ... very magic.

Wow I was just watching a video about why this happens and then see your toot :unacceptable:

@kurbitur awesome, thanks! :) more complex circumstances than I thought (also suspected a capacitor :)), mind blown!
