Floodlight Energy Calculator (Cost and kWh Usage)

Floodlights are commonly used to light up outdoor areas such as parking lots, sports fields, and building exteriors. They are also used for security purposes in residential areas.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

On average, a Floodlight uses 1000 watts of power per hour. This means that if you leave your floodlights on for 10 hours a day, the energy consumption would be 10,000 watts or 10 kWh (kilowatt-hours) per day. If you use your floodlights every day, you would consume 300 kWh per month or 3,650 kWh per year.

It’s important to know the energy consumption of your appliances as it can help you understand your energy usage and make more informed decisions about your energy usage habits.

The energy consumption of Floodlights can have a significant impact on your electricity bill. The more Floodlights you have and the longer you use them, the higher your energy costs will be. This can be a burden on your budget and have a negative impact on the environment.

Cost in Dollars of Energy Usage

The formula to calculate the cost of energy usage is:

Energy Consumption (kWh) x Energy Price ($/kWh) = Cost of Energy Usage ($)

Using the default energy price of $0.12 per kWh, the estimated cost of using a floodlight for 10 hours per day is:

10 kWh x $0.12/kWh = $1.20 per day

This translates to:

  • $36.50 per month
  • $438 per year

Money Saving Tips

Here are some ways to save money on your floodlight energy costs:

  • Use LED Floodlights: LED Floodlights consume less energy than traditional Floodlights and have a longer lifespan, which reduces your overall cost.
  • Use Motion Sensors: Motion sensors can detect movement and automatically turn on your Floodlights, reducing the amount of time they are on and saving you money.
  • Use Timers: Timers can be used to turn your Floodlights on and off at specific times, reducing energy consumption and costs.

By following these tips, you can save money on your energy bill while still enjoying the benefits of your Floodlights.


Floodlights are an important part of outdoor lighting, but they can be costly if not managed properly. Understanding the energy consumption and cost of using Floodlights is crucial to managing your energy costs and reducing your environmental impact. By following the money-saving tips outlined above, you can reduce your energy usage and save money on your energy bills.
