Lighting Question

If I plan to support 3-5 plants, will a 400w HPS be sufficient or should I just suck it up and pay the extra $90 for a 600w?

Also, does it matter if I'm running 120, 240, or 480 volt? I know the electric usage will change and thus my bills a little lower, but it is really worth running a seperate line for this if I have standard 120 already? How much would I really be saving?

Any thoughts or answers would be well appreciated. Thanks.
