The formula you are looking for is W = I x E. Watts = Amps x Volts. If you can find the two values on the fixture's label then use the formula to find the wattage of the fixture.
About 150 watts.
The total wattage of the light fixture with 3 60-watt bulbs is 180 watts (3 bulbs x 60 watts per bulb).
Look on the ballast inside of the fixture. There is an amperage and a voltage on the ballast label. Use this equation to find the wattage. W = I x E, Watts = Amps x Volts. This will give you the answer that you are looking for.
A fluorescent fixture with no tubes installed will still consume power, typically around 5-10 watts due to the ballast and other internal components. This power consumption is significantly lower compared to when the tubes are installed and the fixture is operating normally.
The watts determine how much energy is taken and how much heat is produced. You need to look at the lumens to see how much light is produced. CFLs produce 4-5 times more lumens than incandescent bulbs, or 3-4 times more than halogens, for the same power in watts.

The recommended wattage for 25 watt light bulbs in this fixture is 25 watts.
The recommended wattage for a 25-watt light bulb in this fixture is 25 watts.
The recommended wattage for a 150 watt light bulb in this fixture is 150 watts.
Look at the wattage capacity of the fixture. Some fixtures are limited to 65 watts, some can take much more. If you use a larger bulb than what the fixture was designed for you create a fire risk. If you need to use a larger bulb but the fixture is limited to 65 watts, you need to change the fixture.
The watts determine how much energy is taken and how much heat is produced. You need to look at the lumens to see how much light is produced. CFLs produce 4-5 times more lumens than incandescent bulbs, or 3-4 times more than halogens, for the same power in watts.
Check the ballast for the amperage and multiply it by the working voltage. This will give you the wattage that the fixture draws.
Yes, it is only pulling 18 watts.
