The average household has 45 light
bulbs. If they were all changed from
incandescent to LED the savings
would be approximately $60 a
month.
Bulb is a Phillips A19 bulb. Cost is
approximately $50 per bulb. Total

Can LED lighting really save energy and money? Take a look
at the statistics. The U.S. Department of Energy estimates that
widespread adoption of LED lighting by 2025 will:





Reduce electricity demands from lighting by 62 percent.
Eliminate 258 million metric tons of carbon emissions.
Reduce the amount of materials being put into landfills.
Avoid the building of 133 new power plants.
Save the US over $280 billion.
