Will a 220 volt choke ballast work the same at 110 volts?

Main Question or Discussion Point

If I use a choke ballast rated for 220 volt at 110 volts, will it still work the same? In other words, if the label says 220 volts 400 watts, will it still operate at 400 w from 110 volts or would the output be reduced to 200 watts?

I do not expect it will work. You want the current to stay the same (actually, you want it to increase if you want power to be the same when voltage is lower), but you need the ballast's voltage drop to be less, with only 110v total now, compared with 220v previously. So I'd say there is no chance it will work.
