Hey wavedash, if you have 120v outlets and want to use those buy the 120v, if you live in the states the standard outlet is 120v, if you live in europe you may have 240v.
So basically if you live in the states and want to use a regular outlet buy the 120v.
A 400w light uses more amps at 120v than at 240v, but a 400w light and a few fans for your room will be no problem on a 15 amp 120v circuit, have a good one and be safe.

240 uses half the power. if ur only getting 1 400w just get the 120 and plug in a regular wall outlet.

They both use same amps 240v is only devided into two lines.
