LED Savings Calculator

LED Savings Calculator
This calculator was designed to provide you with the most accurate and customized information on how you could save by switching a incandescent or fluorescent bulb to an LED bulb. Simply enter how much you pay for electricity, what type of bulb you're replacing, and how many hours you leave this light on per day. After you've filled it in, click outside of the box to calculate your monetary savings (in electricity and bulb replacement) and how much you'll save the environment (by reducing your CO2 and mercury output). If you don't know know a variable, use our default values.

The energy efficiency of LED bulbs translates directly into environmental benefits

Switching your old bulb to a 3W LED would prevent about this much carbon dioxide from being emitted (lbs):

1 year

2 years

5 years

10 years

20years

30years

It would also keep about this much mercury from entering the environment (mg):*

1 year

2 years

5 years

10 years
