Assuming that's how the transformer is designed, yes. If it's a conventional
transformer chances are good.
If it's a solid state, bear in mind that the '30mA' reading is usually a
qualitative rating. i.e. the transformers are either outputting the
equivalent light or lighting the equivalent length as a conventional
transformer of similar rating.
I can for example with a 125W high frequency flyback transformer, easily
light the equivalent length that a 225W conventional tranformer would.
In this case you might want to profile the primary current against known
neon units. And create a scale based on that. In general there should
still be a more or less directly proportionate relationship between input
current and output.voltage.
