I measured the diameter at 25 - pretty close!

Wait, it's even less than that. It's about 0.85 Watts over my
long piece of wire. Per meter it's only 0.06 Watts.
In the name of science I just tried lighting up some LEDs
with a ten foot piece of 33 SWG transformer wire to see
what happens.
Answer: It works fine. It's been lit up for over an hour and
all voltage/current readings are correct.
I was expecting the wire to get hot, maybe even melt,
but if it's getting any warmer it's not enough to feel.
