Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts.
It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1

How much energy does a 250watt bulb use per hour How much energy does the average light bulb use per hour?
There are many factors that go into calculating the energy usage of a light bulb. The wattage printed on the lamp is only the energy use of the lamp when it is new. Depending on the kind of lamp he energy required to run it will increase as it ages. For example a Metal Halide lamp can use up to 50% more power in the last 20% of its life.Another factor is the ballast that may be required to run the lamp. Each ballast has a "ballast factor" which can increase or reduce the overall energy usage of the lamp. Many ballasts have a factor as high as 1.2 which would increase the energy consumption of the lamp to 300 watts.AnswerThe question is asking about energy, not power as per the previous answer. To find the energy consumed by a lamp, or any device come to that, multiply its power rating by the time for which it is used. So a 250-W lamp will use 250 W.h (watt hours) of energy in one hour, 500 W.h in two hours, and so on. Energy is more-commonly expressed in kilowatt hours, for the purpose of billing however, where 250 W.h corresponds to 0.25 kW.h, etcAnswer: In an hour it uses 250 watt-hours. The average bulb probably uses 20-60 watt-hours each hour.
How much energy is used to produce 1 piece of paper?

What kind of resource is solar energy?
Solar energy is a reusable/inexhaustible resource which means it can be used as much as you want without running out of the resource.
The watts in a light bulb named after James Watt?
The watt was named after James Watt. The term watt in electric appliances refers the rate at which energy is generated or consumed and therefore is measured in units (e.g. watts) that represent energy per unit time. An example; when a light bulb with a power rating of 100W is turned on for one hour, the energy used is 100 watt hours (The watt second is a unit of energy, equal to the joule).
How much of the Sun energy is absorbed by the Earth's surface?
AnswerApproximately 120,000 TW (terrawatts)That is 120000000000000000 joules per second!More energy hits the Earth from the Sun in one hour that the whole world uses all year.(The world uses 15 terrawatts of power per year.)

Where was the first automatic streetlight system in the US installed in 1949?
The first automatic streetlight system was installed in New Milford, Connecticut in 1949. The first traffic light was used in 1914 in Cleveland.
The rate which electrucal energy does work?
I believe you are thinking of a watt perr hour or more commonly used is a kilo-watt-hour - that's the amount of power used in an hour, not exactly how much work is done however.
What does a kilowatt-hour measure?
It is a unit of energy. If energy is transferred at a rate (power) of one kilowatt, during one hour, then one kilowatt-hour (kilowatt times hour) of energy will be transferred. Since a joule is equal to a watt-second, a kilowatt-hour is the same as 3.6 million joules.
How much electicity is used in a 48 watt bulb in an hour?
It uses 48 watt-hours each hour. In 20 hours and 50 minutes it uses 1 kilowatt-hour or 1 unit of electrical energy, which costs about £0.15
What is the definition of electricity bill?
It is the amount in Rs. or Roller which is paid for how much unit of electrical energy consumed. the unit of electrical energy is KW h (kilowatt hour).
What is electrity in units?
watts or kilowatts are used to measure power, which is how quickly energy flows, and electrical energy is measured in kilowatt-hours. A kilowatt-hour is also known as a Unit of electrical energy, and it is the amount of energy used when a power of 1 kilowatt flows for 1 hour.
