It's my understanding you should use the "rated" value (400mA) for impedance.
The matched size is based on it and it doesn't change. But the limited
current
means you will only turn up Vin to about 2600W or 170V max. But if I'm
mistaken
here, I hope someone will correct me.

I thought our inductive ballast in the primary circuit effectively increasd
the inductance of the transformer and essentially produces the same as rated
voltage (less some resistive loss) at a lower current - thus you should
calculate based on the reduced current figure.
