Some of the other nice people of s.e.l. will most likely
also warn you of the dangers. Please don't do it.

I wasn't going to do it, it was a question in a test I wrote,
and it seems I responded incorrectly because I assumed that a
bigger ballast will have higher inductance, which means higher
impedance and smaller current.

Well, "bigger" ballast means lower inductance and thus impedance.

A 250W mercury ballast has roughly half the impedance of a 125W mercury ballast.

"There's ALWAYS a mistake somewhere"

Thank's for this reply -- warning -- it is a question that naturaly
occour and I wonder why I havn't seen the question answered so
directly before. Guess it shuld be the first warning realy, as it is
an obvious thing to ask.

Most HID lamps include a warning that they should be
operated ONLY on ballasts designed for that lamp.
