Lumatek lk1000 240 volt conversion questions

[Bern813]

I have an older lumatek lk1000 that I've been running at 120 volts. I want to switch over to 240 volts. Do I have to rewire something internally on the ballast or does the ballast automatically sense the difference in voltage?

Post a pic of the label on the ballast with as much detail as you can get and I'll help ya.

But why? Blowing breakers and want to reduce amps?
