Bill, I don't think a transformer, in itself, is an inductive load. It
reflects into the circuit whatever is connected across the secondary. A
battery charger hooked to a resistive load would look to the dimmer like a
resistive load. An exception would be a welding transformer, which is
usually deliberately wound to have a lot of leakage flux, to limit the
current--this would act as an inductance.
I used a dimmer to control the speed of a vacuum cleaner motor acting as the
blower on a forge. THAT was an inductive load, and even there, it lasted
until I stopped using it.
That said, I think your microscope lamp controller is a neat way to control
a pyrography pen, and you have my bid.
