Below is a simple way for you to calculate how much your lights are consuming in dollar terms on an annual basis. Use the Annual Wattage Consumption Calculator and Comparison LED to calculate how much your lights are costing you. We’ve also included a way for you to calculate what an LED upgrade will save you in dollars and how to calculate your Payback in Years on the upgrade.
It’s important to note that the Actual Wattage Consumption does differ from the wattage on the lamp, especially when there is a ballast or external driver involved. We show you how to test your fixture to get the real number.
For more information see our page dedicated to “How to test your fixture/lamps actual wattage”. You may also be interested in viewing our “How to conduct a “Lighting Audit” page
