How is LED lighting different than other light sources, such as incandescent and Compact Fluorescent (CFL)?

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. However, it also means that sophisticated engineering is needed to produce an LED light bulb that shines light in every direction.

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.

In a CFL, an electric current flows between electrodes at each end of a tube containing gases. This reaction produces ultraviolet (UV) light and heat. The UV light is transformed into visible light when it strikes a phosphor coating on the inside of the bulb. Learn more about CFLs.

Incandescent bulbs produce light using electricity to heat a metal filament until it becomes “white” hot or is said to incandesce. As a result, incandescent bulbs release 90% of their energy as heat.

Why should I choose ENERGY STAR certified LED lighting products?

There are more lighting options available today than ever before. Despite that, ENERGY STAR is still the simple choice to save on your utility bills.

LED bulbs that have earned the ENERGY STAR are subject to very specific requirements designed to replicate the experience you are used to with a standard bulb—so they can be used for a wide variety of applications. As the graphic on the right demonstrates, a general purpose LED bulb that does not qualify for the ENERGY STAR may not distribute light everywhere and could prove to be a disappointment if used in a table lamp.

ENERGY STAR means high quality and performance, particularly in the following areas:

• Color Quality

• 5 different requirements for color to ensure quality up front and over time

• Light Output

• Light output minimums to ensure you get enough light

• Light distribution requirements to ensure the light goes where you need it

• Guidelines for equivalency claims to take the guess-work out of replacement

• Peace of mind

• Verified compliance with more than 20 requirements to address performance and labeling

• Long-term testing to back up lifetime claims

• Testing to stress the products in operating environments similar to how you will use the product in your home

• 3-year minimum warranty requirement

And as with all ENERGY STAR products, certified LED bulbs are subject to random testing every year to ensure they continue to meet the ENERGY STAR requirements.
