Incandescent light bulbs are very useful.
They are a high dissipation resistor with a lot of uses.
I have one in series with a bathroom ceiling fan, just kept plugging
smaller watt values in
until the fan was quiet enough but still fully functional.
I have one in series with a micro drill press, runs with full revs
but stops when the drill jams.
It will be a pity to see them turn to unobtainium.
