It depends on the type of double fluorescent fixture and the tubes you use in it.
If you use regular T-12 tubes, you would use 80 watts plus whatever losses you get from the ballast (up to 20 watts).
If you use energy saver T-12 tubes, you would use 68 watts plus the losses from the ballast.
If you use a T-8 fixture, you would use 64 watts plus whatever losses from the electronic ballast which are next to nothing in comparison to a magnetic T-12 ballast.

Depends on the specific light. A range might be between 10 and 40 watts per tube for most applications in a residence or small business.
Multiply the current by the voltage: 120 times 0.3, which is 40 watts.
The wattage of a lighthouse light can vary depending on the size and type of light being used. Traditional lighthouse lights can range from 1000 to 2000 watts, while more modern LED lights may require less power, typically around 100 to 200 watts.

Thomas Edison's first practical incandescent light bulb had a power consumption of around 60 watts.
Divide the wattage by the voltage. If it is 120Volt then the answer is .15Amp
