0.6 kW times 18 hours = 10.8 kWh.
In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
led bulb lasts for more than 24 hours if they glow continuously but if we use the periodically(from some time to time ) they lasts long for many years
it varys from light bulb to light bulb.
The correct voltage should be printed on the light bulb.
Takes 300 hours for the average light bulb to burn out

In ten hours, a 200W bulb will use: 10 * 200 = 2000 Watt-hours = 2 kwh
Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
A 30-watt bulb uses 0.03 kilowatt-hours every hour, or 30 kilowatt-hours in 1000 hours. To find the kilowatt-hours, multiply 0.03 by the time in hours.
