Are these a noise source?

In archives there seems to be a preference for mechanical dimmers.
I have a string of 4 LED's for which I could probably find an acceptable range of light by using a rotary switch and 4 different resistors.
But it's another project I don't need if a 15 buck dimmer will not cause problems.

"Mechanical"?????? We used to offer a range of
linear electronic dimmers. I think Eric's dimmer at:
http://www.periheliondesign.com/egpavr.htm
is a compact, linear device that is sure to be
noise free.

Give it a try. The risk is low. Then you can report
back to us whether or not the dimmer is suited for
the purpose you used it.
