How do you convert 12 volt to 110?

Answer 1

It depends on the amperage that the light needs. One of the new style, LED bulbs needs only a small fraction of what a large 12 volt spotlight needs. It is not unusual to see a headlight bulb rated at 4 to 5 amps. Since a typical home light needs no more than a little over one amp, you are putting a lot more though the switch than it normally is made for.

A smaller bulb, like those for an interior light or tail light in a car is fine. The more bulbs on a circuit, the more amps it will take. Take the total wattage of all the bulbs and divide by 12 to get the amperage. Note that an automobile actually has over 13 volts, even though we call it 12 volts, but that is not a big enough consideration at this point.

Get a switch that is rated at over the total amperage.

Bottom line, one interior light bulb on a 120 volt rated home lighting switch is fine, but multiple headlights are not. You need to do the calculation for anything in between that.

The amperage rating of the switch is stamped on the metal and is listed on the box that it comes in. (ex...15A 120V)

Answer 2

No, unless it is a box that separates the high and low voltage. You could gang together two boxes provided there was a separating wall between the voltages. The danger is that the high voltage shorts to the low voltage.

Answer 3

NO 110 Ac is not compatible with the 12 V DC . You could cause the battery to explode. That is what a battery charger does. convert 110 Ac to ~15 V DC to charge a battery.

Answer 4

If 12 volts DC then you buy an inverter with the desired wattage rating. If 12 volts AC you would need a step-up transformer of the proper rating.

Answer 5

It MAY work, if you wire the fixture to 110 Volts. But there are risks to using a higher voltage than a fixture is engineered for.
