At 10 cents per kWh (Kilowatt hour), one 100 watt incandescent light bulb ran for 24 hours straight will cost 24 cents a day. $7.30 a month, $87.60 a year.
kWh = (Watts Used * Hours per Day * Days per Month) / 1000
Cost per Month = kWh * Cost per kWh
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.
Is the bulb a 1.5 volt bulb? A 3 volt bulb? A 12 volt bulb or a 120 volt bulb?Or does it have some other voltage such as 230 volts which is very common in Europe and many other countries of the world?What is the wattage of the "big light bulb"?This question cannot be answered without knowing at least the voltage and the wattage of the light bulb that is being asked about.
Yes it it is a 12 volt DC light bulb. It will not operate a household 120 volt light bulb.
Yes, for about .1 second, then it will blow the lamp. A 9v battery will however light three 3.5v lamps.
Yes, a 12 volt auto light bulb can work on 12 volt AC, but the light output might be slightly lower compared to when using DC. The bulb will still produce light, but it may flicker due to the alternating current.
Um, a 5 volt light bulb?
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
Choose a bulb with the same voltage as your fixture to prevent damage or risk of overheating. If the fixture specifies 120 volts, use a 120-volt bulb. If in doubt, consult the manufacturer's instructions or a professional electrician.
A 13.5 volt bulb will burn less brightly but last longer.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
From stores which sell light bulbs for flashlamps.
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.
