Understanding Your Options

What is a CFL?

The CFL – or compact fluorescent light bulb – is an energy-efficient light bulb. CFL light bulbs last about 5 times longer than incandescent bulbs and use about 75 percent less energy. For example, a 15-watt CFL provides the same amount of light as a 60-watt incandescent.

What is an LED?

The LED or Light Emitting Diode bulbs also use about 75 percent less energy than traditonal incandescent light bulbs, and last more than 15 times longer.

Why does changing light bulbs make such a difference?

Lighting can account for up to 20 percent of the average home’s electric usage. Replacing incandescent bulbs with CFL’s or LED’s, which can use up to 75 percent less energy, can result in substantial savings over the life of each bulb you replace. Over time, your total savings can be significant!



ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy. ENERGY STAR’s goal is to help save money and protect the environment through energy-efficient products and practices.

How are ENERGY STAR® qualified CFL’s and LED’s different?

ENERGY STAR® qualified CFL’s and LED’s are different from the other CFL’s and LED’s because they meet strict government operating standards. To earn an ENERGY STAR® label, light bulbs and fixtures must pass extensive tests to ensure high-quality light production.

How do I dispose of CFL’s and LED’s?

CFL’s can be recycled at The Home Depot and Lowe’s and at other locations in your community. LED’s can be disposed of in normal household trash.
