Energy-Efficient Light Bulbs


Twist and save with efficient LEDs

Participating retailers offer discount pricing on qualified LED (light-emitting diode) bulbs. There’s no easier or quicker way to get on the path to greater home energy savings. Make the switch to ENERGY STAR® rated LED bulbs and lower your lighting costs by up to 75 percent. Look for our in-store signage to find specially priced bulbs.

Long-lasting performance

Along with their outstanding efficiency, ENERGY STAR rated LEDs can last up to 25 brilliant years. That means less time on the ladder swapping out bulbs, and less trips to the store purchasing replacements. Once you make the move to LEDs, you’re set for a very long time.

Get more lumens out of your watts

LEDs should be judged by the amount of light they provide (lumens) rather than the amount of energy they consume (watts). The more lumens, the brighter the light.

Find the right color temperature

LEDs produce varying shades of light measured in kelvin (K). Bulbs with lower kelvin numbers have a warmer color, while higher kelvin numbers have a cooler color. For light that most closely matches the color of an incandescent bulb, choose bulbs labeled “warm white” or “soft white.”
