The bulb's power, 75 watts, is the power it uses continuously all the time it is switched on.
The energy it uses can be measured in watt-seconds (Joules) or in watt-hours. A 75 watt bulb uses 75 watt-hours each hour, which is 0.075 kilowatt-hour.
A kilowatt is 1,000 watts. A 60 watt bulb uses 60 watts in an hour. So, in half an hour it uses 30 watts. Now if a kilowatt costs 20 cents, what does 0.03 kilowatt cost?
2300 watt-hours for every hour it operates. Watts x Hours = watt hours.
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
To cool a 1000-watt bulb, you'll need to account for the heat it generates. A 1000-watt light bulb produces approximately 1000 watts of heat, which is equivalent to about 3,412 BTU per hour (since 1 watt equals approximately 3.412 BTU/hour). Therefore, to effectively cool a 1000-watt bulb, you would need an air conditioning system or cooling mechanism that can remove that amount of heat, around 3,412 BTU/hour.

0.04 kilowatts one kilowatt is 1000 watts
A 150 watt light bulb consumes 150 watts of energy per hour when it is turned on.
If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
A 32 watt bulb uses 32 watt-hours, or 0.032 kWh, every hour it is used.
About 90 percent of an incandescent bulb's energy is turned into heat; one watt is 3.41 btu/hr, so 10 watts would be about 3 btu per hour.
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

The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours. Actually there are different definitions of the BTU.The energy unit is not watts per hour, but watts times hour, simply called watt-hours.One BTU is equal to about 1055 Joules or Watt-seconds; that is about 0.293 watt-hours.

Your question is rather like asking, 'How many miles per hour do you do in one hour?' A watt is simply the rate at which you use energy or do work, and it is the same regardless of over what period it is measured.
