It is a magnetic ballast that can be used with either 120v or 240v. I don't believe the bulb needs to be changed with a change in supply voltage. Maybe the best way to figure it out would to just wire it on 120v, check the amp draw.. then change the supply to 240v and check amp draw because...

Is that the same for a magnetic ballast?

But now that I realize the bulb doesn't need to be replaced and can run on 120 or 240v.

Thanks! I forgot about the fact the bulb must be replaced... although the ballast remains the same.

Obviously that is what I am doing. A little direction would be helpful.

Exactly what happens in my example. But I have read elsewhere that the current is directly proportional to the increase/ decrease of voltage.

I am a little confused on how an increase in voltage would increase current. If i have a 1000w fixture with 120vac supplied the current will be 8.333amps After increasing the voltage to 240vac, the same 1000w fixture would draw 4.16 amps. Please help me understand what I am missing here.
