Savings Calculator


Use this LED savings calculator to find out how much money you’ll be saving when you install our LED Lights.

The calculator assumes an average incandescent bulb lifetime of 1,000 hours and an average LED house light lifetime of 50,000 hours.

Feel free to change the values based on the advertised lifetime hours of either the original bulb or replacement bulb, or both.
