The answer is 40 watts, power is a rate of energy. If you are looking for the total amount of energy it uses over its life, take its expected life and multiply it by 40 watts, which will give you your watt-hours.
For example
Expected life of the bulb is 2000 hrs
Then it would be 2000*40 = 80,000 watt - hours or 80 KW-Hours
Power companys charge by the KW hour used

Fluorescent lamps can output a total of 100 lumens per watt. Fluorescent lamps were invented by Peter Cooper Hewitt in 1901.
About 50 lumens per watt for a fluorescent tube, compared to 10 lumens per watt for an incandescent bulb.

six main component of fluorescent tube light
A four tube fluorescent luminaire is just 4 separate fluorescent lamp circuits in one fitting. Look up 'how things work' etc to see a fluorescent lamp circuit.
Depends if ballast is in fixture and switch is on. Several watts if new ballast and perhaps 15 watts for old ballasts....
a 18watt plc fluorescent tube renders 1800lux
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.

Watts are a unit of power. So 40 watts of power to an LED are the same as 40 watts of power to a fluorescent. Sometimes LEDs are rated in equivalent watts which is an attempt to relate watts to brightness or lumens. You need to compare lumens and the "temperature" of the bulbs in Kelvin to get the comparison I think you are looking for.
3 watts to 125 watts.

Electric lights that use from 0.02 watts to 50,000 watts have been manufactured. The CFLs, fluorescent tubes, and incandescent bulbs in your house probably operate in the range of 20-100 watts.

It depends on the voltage and whether the lamps are actually 40 watts or 40 watt equivalent. Watts / volts = amps
