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

How many watts of led equals 40 watts of fluorescent?
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.
