How do you calculate the wattage of a light bulb per hour?

5 watt led bulb power consumption per hour:

Yearly power consumption = 5*24*365 + 10% power loss = 43800 + 4380 = 48180 Watts hour. Converting into units 48.18 units per year is the yearly consumption of 5 watts LED bulbs.

How many kWh does a 40w bulb use?
