Let's say you have a 60 watt bulb. At 120 VAC that bulb will draw 1/2 amp.

By Ohm's Law: Volts = Current x Resistance. Therefore, the resistance of the bulb filament is 240 Ohms.

If 12 volts is applied across 240 Ohms the current = 12/240 or 1/20 of an amp. This small current will not be sufficient to heat up the filament and provide useful light. You might see a small glow in a dark room.

How man watts per hour does a 20 watt 12 volt lamp use?

A 20 watt 12 volt lamp will consume 20 watts of power per hour. The wattage represents the amount of power consumed by the lamp, and the 12 volts indicates the voltage at which it operates.


What bulb do you use for 12 volt instead of a t1133 6 volt bulb?

A couple quick questions first please ... why are you using a 12 volt lamp in a 6 volt system? Have you increased the system voltage? Simply replacing a 6 volt bulb with a 12 volt bulb will cause the 12 volt bulb to burn dim ... Some systems have electrical circuits that drop (decrease) the voltage to certain units (like lights). For instance, your car is a 12 volt system (actually 14 when alternator is operating) and that 12 volts can be reduced with resistors to supply only 6 of those volts to a light ... or other device. Simply replacing with a 12 volt lamp will cause it to burn dimmer. Sorry to answer with a question but, I am just curious ...


What wire size is used for 100 watt 12 volt lamp?

For a 100 watt 12 volt lamp, you should use a wire gauge size of at least 18 AWG to ensure it can handle the current without overheating. It's always best to refer to the manufacturer's recommendations for the specific lamp you are using.


Is 12 volt is enough for a 100 watt light bulb?

12 volts is enough for a 12-volt 100-watt light bulb. It would not be enough for a 120-volt or 240-volt bulb.


Can you use a 145 volt bulb in a 120 volt lamp?

No, a light bulb rated to work in a 120 volt lamp will not work properly in a 12 or 24 volt low volt lighting fixture. I don't believe it will harm the fixture. If you did get a 120 volt light bulb to fit into a low voltage light it would probably just be dim.

Yes, it can be connected safely but the lamp will not emit any light.


Can you use a 12 volt LED light bulb in a 120 volt light bulb socket?

Yes, as long as it has a filament for producing light for example a Tungsten Halogen Lamp, normal Incandescent or GLS lamp. If the lamp is rated at 12v it will run on either 12vac or 12vdc.
