Correct you are, but what happens to a fixture that is rated for
a 100 watt incandescent bulb when you use it for something other
than lighting? Are you saying that as long as you don't develop
100 watts of heat then the fixture will be just fine?

Yes, so long as you aren't actually drawing more than 100W.

So a fixture that is rated for a 100 watt incandescent that would
normally draw less than 1 amp can draw 20 amps as long as there
is no heat involved?
