there is no such thing as a free lunch power consumption is directly proportional to current draw firstly you need to convert mains voltage to12volt via a transformer the advantage to 12 volt lighting is only recognised when using lower wattage halogen or led lighting. as far as i am aware the use of a mains voltage 100watt globe draws the same if not slightly less than a12volt 100watt light as the transformer uses power (in the form of heat) to produce 12volt at least this is what all my "sparky" contacts tell me . my own experience has shown led lighting to be the way to go , i am using a small deep cycle battery ,a small solar panel and leds so far so good with more and more 12volt led lights becoming available

Will a 240 volt string of Christmas lights work on a 110 volt socket?
Yes, but the lamp output wattage will be a quarter of what it is at 240 volts.power = voltage squared / resistance
Can one leg of a 240 volt circuit be capped and the circuit breaker changed to make an existing 240 volt outlet into a 120 volt outlet?
Yes, you can always have heavier wire than code requires.
Can you install a receptacle that is rated for 240 volts to a 277 volt line?
No, the receptacle's rating is 240 volt and that is the maximum voltage allow to be applied to that device. To prevent this condition from happening 277 volt receptacles and switches have a larger box that they fit into. The retaining screws are set apart further that a 240 volt device which makes it impossible to install a 240 volt device in a 277 volt junction box.
Does a 120 volt light use less than a 240 volt light?
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
Is it cheaper to run a 240 volt window air conditioner than a 120 volt widow air conditioner with same BTU?
Your electric bill is computed in kilowatt-hours. This is a measure of power over a period of time, which is a combination of volts and amps. Amperage at 240v would be half that of 120v, but obviously the voltage is double. So the net watts are the same. As a result, your net kilowatt-hours will be the same whether you use 120v or 240v.

Why use 12volt lighting rather than 240 volt?
Because 240 volts is dangerous
How can you get 277V from residential service?
1You could get 220-240V from using the two live ["hot"] wires rather than one live and one neutral. 2Tim, Industrial control transformers are available to get 120 volts from 277 volt systems. If you feed one of these with 120 volts to the secondary coil, it will put out 277 volt from the primary. However, these are rare and are not cheap. If you are trying to use surplus 277 volt fluorescent lights on a 120 volt system, it would be cheaper to replace the ballasts in the fixtures. Another approach would be to use an autotransformer with a 240 volt primary and a 32 volt secondary. If you feed it with 240 volt and wire it to boost +32 volts that will give you 272 volt which should run the lights. But again, you are looking at $60 - $100 for one circuit of lights. 3If you have access to three phase power..... Phase to ground on a 480v 3 phase system is 277v.

What is more efficient to run a pool pump on 120 Volt or 240 Volt?
240
Can you convert 110 volt to 240 volt?
Yes

Why is 240 volt electricity more dangerous than 12 volt electricity?
It is neither more or less dangerous . The determining danger factor is amperage.
Does a 120 volt light use less than a 240 volt light?
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
Does a 6 amp 240 volt appliance hook up to 110?
No, a 240 volt device runs on 240, and a 120 volt device runs on 120. Attempting to run a device on incompatible voltage results in damage.
Can you wire a 240 volt window ac from a 277 volt feed?
no
