15 w * 24 h = 360 watt-hours. [conversion: 360 (w-h) /1000 (w/kw)= .36 kilowatt-hours]
So, .36 times your local electricity supply and delivery rate (in kilowatt-hours).
For me, supply and delivery of 1 kilowatt-hour is $3.25 (you can find this on your bill)
So, .36 * 3.25= $1.17 to run 15 watt light for 24 hours
To calculate the running cost of a 15 watt light bulb over 24 hours, you can use the formula: (Wattage x Hours in use) / 1000 x Electricity rate per kWh. If we assume an average electricity rate of $0.12 per kWh, the running cost would be: (15 watts x 24 hours) / 1000 x $0.12 = $0.0432.
It depends on how much your electricity costs.

To find this answer multiply your wattage by the amount of hours of use. Take that product and multiply it by the amount that your utility company charges you for each kilowatt hour used.
The cost to run a 28 watt light bulb for 24 hours a day will vary on the price per kilowatt hour. A 28 watt light bulb uses 672 watts in a 24 hours period. This comes to 0.672kw hours in that time frame. If you spend $0.15 a kilwatt hour it would cost $0.10 for the day.

Cost of running a grow light?
The cost of running a grow light depends on the wattage of the light, the number of hours it is on, and the electricity rate in your area. To calculate the cost, you can multiply the wattage of the light by the number of hours it is on daily, then divide by 1000 to get the daily kilowatt-hour usage. Finally, multiply this by the electricity rate to get the daily cost of running the grow light.
How much electricity costs when a light bulb is on for a long period of time?
The cost of electricity for a light bulb being on for a long time depends on the wattage of the bulb, the electricity rate per kilowatt-hour, and the duration it is on. To calculate the cost, you can use the formula: (Wattage of bulb / 1000) * hours on * cost per kilowatt-hour.
How much does it cost to burn 7.5 watt night light bulb?
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
How much does it cost to run a 1000 watt light bulb in 24 hours?
The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
How much does it cost to run a 32w T8 fluorescent bulb?
On average, a 32W T8 fluorescent bulb running 24 hours a day for 30 days at an average electricity rate of $0.12 per kilowatt-hour would cost about $7.84 per month.
How much does it cost you to burn a 0 watt light bulb for 24 hours a cost of 0.085156 per kwh?
A 0 Watt bulb does not consume electric power so the cost is zero.
How much does it cost to run a light bulb?
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.
How much does it cost in cents to run a 60 watt light bulb?
In 100 hours it will use 6 kilowatt-hours (units) of electrical energywhich would cost around £1 or $1.
