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?

Thats a nonsensical question. If you are drawing 20A of 120v AC electricity, you
are using 2400w of electricity*. And there will always be heat involved.

*Assuming the power factor is 1, which for light bulbs and most residential
useage, is true.
