So the difference in trolling and not trolling is shown, this is trolling:
Von, you need a course in basic electronics again. I hope someday I will not able to plug my ballast in your ass and have light. Watts are watts no matter what circuit they run on. I dont care if its battery, powerline or directly off a nuclear reactor. There is a basic math program Ohms wrote called Ohms Law to help keep dumbasses from frying themselves. Von dont take it to heart and try to beat me down with your applied mathematics on electricity, my head hurts from reading your bullshit already.
No matter how you stack it if you were to read an appliance rated at 1k watts and it wasnt drawing the rated watts, you have a device that may need repaired or has a supply problem. Point blank and simple. I will say there is a leinance in said value what that leinance value is I havent a clue without a circuit board diagram, which leads us to appliance repair technicians who will use OHMS LAW for this reason:
Inside electrical devices are resistors, capactitors, and etc. Each drawing electricity amplifying it or choking it depending on needs and loads of a given circuit. These circuits have a set voltage value and amperage rating. Hence terms amps and milli amps, and volts and millivolts, and of course ohm measurement as well, and lets not forget watts which led us to this discussion to begin with. These values are used for testing circuits from printed circuit boards to cords, wires and such. The printed circuit boards will have various capacitors, diodes, shunts, relays what have ya. Testing those said items can reveal if they are good or bad, by using the values of each item measured. As we test each circuit we need to know Ohms Law to keep everything within the manufactures specifications, or if building our own electronic circuit/board. To determine the wattage draw we again use Ohms law to ensure final output is within operating specifications. If we couldnt use the law as written, and followed Vons Bullshit theory..... we would be left with electronic devices blowing fuses or operating like a starter on a car with a dead battery. In other words in a vortex blackhole or power outage state of mind with no way of fixing whats wrong with the device or even a simple light.
So in essence a long way to say this, each device rated at 1k is going to draw at or damn near 1k of juice regardless of 110 or 240 unless its bad or you live in Vons neighborhood.
For the rest of the world 240 is more efficient due to being capable of providing higher voltage/amperage to power hungry appliances/lights/pumps/what have ya with lower resistance.
It will not lower wattages used on any circuit. It will lower amperage, which we dont pay for we pay kw.
FWIW here is a good outside link that isnt cluttered with bullshit on How to properly use ohms law.

Ignore the 12 volt part, its same law on any given circuit, only time ac and dc makes a difference is when using one for another, and a complete other topic.
