I have some lights in a rough space that are plug-in lights. To power
them, last year I wired up a duplex receptacle high up by the
ceiling. Power to that outlet is controlled by a single pole switch
at regular height.

Here's my question: is it ok to replace that switch with a dimmer?
Nothing else would ever be plugged into the outlet. You can't even
reach it without an 8' ladder.

That's fine, what you don't want to do, is wire a receptacle to a dimmer, in
a location that someone might plug in a vacuum
