It depends on the bulb, how many watts it is.
All bulbs are marked with the correct voltage and the power taken, in watts. You multiply the watts by the number of hours to find the watt-hours of energy used. Then divide by 1000 to find the kilowatt-hours. A kilowatt-hour is also called a unit and you pay about £0.15 for a unit of electricity.
Let's say it's a 100 watt bulb running for 24 hours. That uses 2400 watt-hours or 2.4 kilowatt-hours, which costs about 2.4 x £0.15 which is £0.36.

To calculate the cost of lighting a 100-watt bulb for 10 hours a day, first convert watts to kilowatts: 100 watts = 0.1 kilowatts. If the bulb is used for 10 hours, that totals 1 kilowatt-hour (0.1 kW x 10 hours). Assuming an average electricity cost of about $0.13 per kilowatt-hour, it would cost approximately $0.13 per day to run the bulb. Over a month, this would amount to about $3.90.
