It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent.
Watts / volts = amps
53000Amps
The power required to run a basic computer will be 1.35 amps for startup and .7 to .9 amps continuous. The power requirements to run an 17" monitor will be 3.5 amps startup and 1.5 amps continuous.
When you buy the bulb. All of those specifications should be on the package. To figure the Kilowatts it's pulling and cost to run. kW = amps x volts / 1000. then just take your kW x price per kw. and that will give you how much it costs to run that bulb for one hour. The amperage is on the label of the ballast. When you connect the ballast to power you will see it along with the voltage and pf of the ballast. F40T12 twin 8 foot tubes, ballast usually draws about .75 amps.

They can, but you need to have a motion sensor/system made for them. They require a ballast to get them to start (in most cases) and don't turn on instantly, making them a poor choice for most security applications. A motion sensor is just a switch so you should have no trouble with fluorescent lights. Older tubes sometimes take longer to fire, try relamping. If the fixture is outside and cold this has a major factor on operation. For outside fluorescent fixtures in real cold climate you need a zero degree ballast. The new electronic ballast are the best as they operate in all kind of temperatures.
If it is a 120volt light, then it is watts / volts. 32 watts / 120 = .2667 amps. <<>> fluorescent lights usually have a power factor around 0.6 so a 32 watt bulb would take around 32/(120 x 0.6) amps or 0.44 amps.
a very long time ..........
Watts= voltage times amps. So if you divide Watts by voltage, you will get amps = .33333 or about a 1/3 amp load. This is assuming a 120 volt circuit.

0.0001 amps will stop your heart if you are fully grounded.
it doesn't matter how many volts pass through your body, its the amps as little as 0.1 amps can kill a human

Lights range from 300 to 1000 watts and there can be hundreds of them. Amps are rated by watts and they are useing many of these at a time. A concert probably uses more power than a very large house does in a year.
Just take the voltage and multiply it by the amps. That should give you a close approximation of the watts used. For instance, 117 volts at 4.5 amps = 5265 watts.
To answer this question the voltage needs to be known.
