Depends on the bulb. There are different sizes.

It is not the wattage of the tubes that is the concern, it is the wattage of the ballast that is connected to the power source that has to be known for circuit loading. Look on the ballast and you will see an amperage that the ballast draws. Use the formula W = A x V to find the line side wattage. Once all of the wattage's have been added up use the formula; I = W/V, this will give you the amperage the circuit so that the wire size and breaker size can be calculated.
<<>> The power used by the bulb, in watts, should be printed somewhere on the bulb. A CFL like the one in the picture would use 15-20 watts.
Incandescent light bulbs are available in all kinds of sizes and shapes and use different amounts of energy depending on their intended uses and sizes.
For household light bulbs, typical energy values range from about 7 to 100 watts.
Low energy types are available using from about 7 to 20 watts and these give out the same range of lighting intensity as conventional incandescent bulbs that use from 60 to 100 watts, so cpmpact fluoresdent light bulbs use about 1/5 (one fifth) of the power to produce the same light.
Look at the ballast and there you will find an amperage that the ballast uses. Also find the voltage that the ballast uses. Use this formula to fine the wattage of the fixture. Watts = Amps x Volts.
There are many variables to take into account to answer this question. The amperage and the voltage to the ballast need to be stated. To find wattage use the following formula, W = I x E. Watts = Amps x Volts. The information that you need can be found on the label of the ballast which is located inside the fixture.
It varies depending on the tube type. A typical long tube (over a meter long) uses 40 watts; that means:* 40 joules/second, or equivalently:
* 0.040 kWh/hour
Similarly, you can look up the rating of any other tube (in watts); the amount in watts is equal to joules/second, or - if you divide it by 1000 - to kWh/hour. The latter is interesting because you typically pay electrical energy by the kWh.
A standard 100 watt incandescent bulb offers the same lumens as a 72 watt incandescent halogen and finally, a compact florescent light (CFL) will use only 23 watts..
If you look on the bulb it's usually marked with the voltage and the power in watts. The power tells you how fast the bulb uses up electrical energy.
The energy in watt-hours every hour is equal to the power in watts. This should be printed on the tube somewhere.
The rating of fluorescent lights, or any other type, is always written on the light. Generally fluorescent lights are more energy efficient than incandescent lights.
1/5 of the amout of incandescent lights.
A typical light bulb wastes 90 percent of electricity. According to the EPD, the typical incandescent light bulb turns only about 10 percent of its electricity into light. A typical light bulb, when on, is hot. That's because 90 percent of the energy is wasted as heat, which means it isn't very energy-efficient. A typical light bulb wastes 90 percent of electricity.

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.
We need 275kj energy to sleep for 1 hour
Convert the watts to kilowatts, multiply by the time to get the energy (in kWh), then multiply by the rate.
You can easily calculate the energy that the photon detects per second by using the relation E=hc/w where E is energy in Joules, h is Planck's constant, c is the speed of light, and w is the wavelength.
The average home fluorescent lamp consumes 40W of power. Running for one hour it will consume 0.04 KWh. Units of electricity are charged per Kilowatt hour.
A 400-watt light uses energy at the rate of 0.4 kilowatt. In 1 hour, it uses 0.4 kilowatt-hour of energy.
That varies a lot, depending on the type of light bulb. The old-fashioned incandescent light bulbs produce much less light, for the same power, than the fluorescent light bulbs.That varies a lot, depending on the type of light bulb.

i saw this on myth busters and it takes more energy to keep a light on.
There is actually no energy efficient light bulbs in a way to interpret in physical determination. Energy efficient means less Watts required per hour compared to non energy efficient.
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
2 tubes
electircal or photo electrical energy. Photons are shot across from panel to another panel this sparking back and forth creates the light you see.Answer: Electricity is the energy input into a light bulb. It either heats afilamanet to produce heat and light, r excites the gas contained in the bulb (in flluorescent tube) to emit visible light directly or emit UV light which interacts with a phosphor coating in the tubes to emit light.
Fluorescent light bulbs are extremely long-lasting. Most are designed to last over 10,000 hours. This comes out to approximately 416 days of continuous 24 hour usage. Even if used only 8 hours/day, the average fluorescent bulb should last over 3 years.
that is dependant on the wattage of the bulb, the wattage 40W, 60W, 100W, is the rated power that a bulb will use. 1kW is equal to 1000W 1kWh is equal to 1000W per hour. kW stands for kilo watt I hope that helps
