lol alright thanks. I was kind of confused because suposidely a electrical socket can only carry 105 volts, and this light requires 120 volts. Could you explain that a little bit. And can i plug anything else into that plug, if its a minor appliance like a laptop charger or a house lamp?
I'm not sure what country you're in, but in the USA household voltage is between 110-120v. Your power company charges you based upon the amount of watts used, not voltage. To figure wattage, multiply volts x amps. In your case, you know you have 55 watt bulbs, so that makes it easier.
Just to confuse things a little, wire is rated by the amps it is capable of carrying. Too many amps makes the wire get hot, possibly leading to a fire.
A fixture with two 55w bulbs should use about one amp. Most household circuits can handle 15 amps. So to answer your second question, yes you can use the same outlet to plug in another lamp or small appliance.
If you are outside the USA disregard what I just said. I have no experience with foreign electrical systems, and I don't wanna be responsible for you burning your house down.
