yes the bulb will actually last longer
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
Technically speaking a bulb and a lamp are the same thing. You can use a 60 watt bulb in a fixture calling for a 40 watt bulb but I wouldn't. The lighting fixture may get to hot, melt and start a fire.
Yes, a 660 watt socket can safely handle a 60 watt bulb. The wattage rating of a socket indicates the maximum amount of power it can handle, so a 60 watt bulb is well within the safe range for a 660 watt socket.
no , it will burn out
No, they do not draw the same current. The current drawn by an electrical device is determined by the power (Watts) and voltage (Volts) using the formula: Current (amps) = Power (Watts) / Voltage (Volts). So, the 12 volt 50 watt bulb will draw higher current compared to the 230 volt 50 watt bulb.
No. It just draws less power.
If the 250 watt bulb is a HID or similar type the ballast comes complete with the fixture. The bulb socket is also part of the fixture and comes pre-wired to the socket. To connect the bulb to the fixture all that has to be done is just screw it into the fixture's socket.
the 220 volt bulp in 220 volt ac current
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.
If the bulb is a 40 watt, 120v bulb, you would need 20 6 volt batteries wired in series, or 80 (!) 1.5 volt batteries. 1.5 volt batteries are AAA, AA, C, D, etc. Since this solution is rather extravagant, try finding a light bulb made for an RV. These typically run off of 12 volts, and you can get a single 12 volt battery, or 2 6 volt batteries, to run this bulb.
Yes, you can use a 10 watt 12 volt bulb instead of a 5 watt bulb as long as the fixture can handle the higher wattage. Just be aware that the 10 watt bulb will be brighter and may generate more heat, so ensure there is proper ventilation and that the fixture can handle the increased power load.
No, a 6 volt battery is not strong enough to power a 40 watt bulb, which typically requires around 12 volts to operate efficiently. You would need a higher voltage power source to light up a 40 watt bulb.
