Replacing just 5 incandescent light bulbs with LEDs can save $60 or more per year in electricity costs! Upgrading to LEDs is one of the easiest ways to save energy and money.
LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than incandescent light bulbs.
The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL). LEDs typically do not “burn out” or fail. Instead, they experience ‘lumen depreciation’, wherein the brightness of the LED dims slowly over time. Unlike incandescent bulbs, LED “lifetime” is established on a prediction of when the light output decreases by 30 percent.
How is LED lighting different than other light sources, such as incandescent and Compact Fluorescent (CFLs)?
- LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer.
- LEDs are “directional” light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently in a multitude of applications.
- Common LED colors include amber, red, green, and blue. To produce white light, different color LEDs are combined or covered with a phosphor material that converts the color of the light to a familiar “white” light used in homes. Phosphor is a yellowish material that covers some LEDs. Colored LEDs are widely used as signal lights and indicator lights, like the power button on a computer.

- They can last up to 10 times longer than traditional incandescent strands.
- They are cool to the touch, reducing the risk of fire.
- They do not have moving parts, filaments or glass, so they are much more durable and shock-resistant than other light strings.
