Not sure if a triac "creates" a phase offset between voltage and current.
AFAIK, a triac only PWM's the input voltage/current ... and that's what
"controls" the brightness of the lamp (heat from the heating element).
I thought only capacitive/inductive elements creates angle shifts .......??

look at the input. approximate the signals with a sine and calculate the phase offset.
there will be some.
I never hooked one up on a wattmeter / phase offset meter, would be nice to know..
(but i have no such meter)
