electronics question -- 230v from 120v?

So, I have acquired this cool lamp, but it is from Italy and requires 230v 50Hz. Since wall sockets here are 120v 60Hz, would it be possible and safe to series two sockets to make 240v 60Hz, and hook it to this thing, or am I better off just replacing the ballast?

If it's an incandescent, so long as the bulb matches the power, it's all good. Flourescent or LED, need to change the transformer.

haha, DO NOT series two outlets. Bad news would follow.

If you have and electric clothes dryer, it would use a 220V outlet, but that'd be just stupid... buy teh ballast.

You cannot series 2 electrical outlets. If you do this prepare to see sparks followed by your breaker tripping (we hope). The only way to get 220 is to use the 2 hots coming from the breaker panel (red and black). You cannot do this from an outlet that is fed 120volts. You can always make a plug 220 volts in the panel by removing the WHITE wire and adding a RED wire in it's spot on the breaker. This will give 220 volts potential across the outlet. You will still need to change the ballast because of the frequency.

Just use a small transformer to kick the 120 to 220. Google 'step-up transformer'

Is european 240 the same as US 240 (aside from frequency)?
ie: 2 legs & 120 each, 180 out of phase?

Typical European power are:

Most household stuff: 230 V (220-240 V), single-phase, 50 Hz, live/neutral/(ground)

Beefier equipment has 400 V (380 V) three-phase.

See if you can track down a 120V->240V "travel" adapter. Radioshack's website has a "proper" one:

If this is too expensive, you can probably get one of the $15 120->240V converters and about $5 in plugs/sockets from home depot and figure out a way to wire it backwards. Just only do this with the ~100 watt converters, the 1600 watt converters can't be run in reverse.
