You generally need the same number of volts for a given amount of light (lumens), regardless of how many hours you use it.
They typically measure the amount of energy used by a bulb in "watts", not volts, and you can find a wide range of wattage ratings from milliwatt LEDs to 1000-watt floodlights and on up.

How long can a battery power a 44 watt light bulb?
To answer this question the amp hour rating of the battery is needed along with the voltage of the battery or bulb.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?

What is the power rating for a light bulb in one hour?
Light bulbs have various ratings. They are rated in Watts.
How many batteries would it take to light a 12 volt 100 watt light bulb?
12 volt batteries vary in size. You need to look at the amp hours of a battery and multiply by the voltage. So, a 100 amp hour battery at 12 volts is 1200 watt hours. 30 watt bulb will eat that up at 30 watts and hour. 1200 divided by 30 is 40 hours. Simple huh!? *Something to keep in mind is if your 30 Watt light bulb is rated 30 watts at 12 volts. If it is rated 30 watts at 24 volts, 110 volts or another voltage it will also change the length of time your battery will last.
How many amps needed for a 9000 btu unit at 240 volts?
9000 BTU/hour is equivalent to 2300 watts so the heater will draw 10 amps on 230 volts.

How is the rating of a light bulb determined for instance 100W 60W is that how many watts an hour to run it?
No, the wattage is determined by the resistance of the filament in the light bulb. The formula to determine the wattage is Watts = Voltage (squared)/Resistance in Ohms. To find the resistance of a 120 volt light bulb use the formula, Resistance in Ohms = Voltage (squared)/Watts. So for a 100 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/100 = 144 ohms. For a 60 watt bulb at 120 volts the resistance is 120 volts x 120 volts = 14400/60 = 240 ohms. As you can see this holds true to Ohm's law, current is inversely proportional to the resistance of the circuit. The higher the resistance of a load, the harder it is for the current to flow. In this case less current results in less light being emitted from the filament in the light bulb.
How many killawatts are in a standard light bulb?
"A standard light bulb I would consider to be a 60 watt light bulb, and kilowatts are the amount of usage in a light bulb. From my research I have found that a standard 60 watt light bulb uses approximately 1.44 Kilowatts per hour."

What is 60w light bulb?
a normal incandescent 60 watt light bulb uses 60 watts of electricity to produce 20 watts worth of light, and 40 watts worth of heat. It is more of a heat bulb than a light bulb. it is great if you can capitalise on the free heat, but if it is not cold in your house, turn it off. is there a better bulb? no. why are they ideal? cheap (as low as 10 cents for the el cheapos), never change shape/design/size/compatability, make pleasant light I could go on for an hour, but the best bulb is the cheapest.
How much a hour does 100 watt bulb use at 15p?
A 100 w light bulb uses one tenth of a kilowatt of power, therefore in 1 hour it uses one tenth of a kilowatt-hour of energy, that is 0.1 units, or 1.5 p.
Why theres a light bulb on youtube logo?
I think it is about earth day.... were the world switch off there lights for an hour
How long does it take to make a hamster run on a wheel to make a light bulb turn on?
About an hour non stop!
How many volts per hour does a 75 kva transformer produce?
Volts per hour is an invalid statement. You may have meant Watts per Hour.
