Shining Light on LEDs: The Basics

With more and more homeowners completing renovations in 2014 and the recent phase out of certain light sources, it seems everyone is talking about LED lighting. These energy-efficient sources provide numerous benefits – from energy savings to aesthetic appeal.

With all the LED buzz, this month, we will be hosting a weekly blog series titled ” Shining Light on LEDs.” Our goal of this series is to to do just that: Shine light on what the LED revolution is all about. Our team of lighting experts comes together to unpack all you need to know to take advantage of these energy efficient sources.

Let’s start with some of the basics about LED lighting:

How LEDs work

  • LED lighting products use light emitting diodes to produce light very efficiently. An electrical current passed through semiconductor material illuminates the tiny light sources we call LEDs. The heat produced is absorbed into a heat sink.

Saving energy with LEDs

  • According to the Department of Energy, “LEDs offer the potential for cutting general lighting energy use nearly in half by 2030, saving energy dollars and carbon emissions in the process.”

Inherent benefits of LEDs

  • LEDs have many unique, inherent benefits including long life, ease of maintenance, resistance to breakage, lack of infrared or ultraviolet emissions, and instant-on performance.

Measuring color in LEDs

  • Color appearance is communicated using correlated color temperature (CCT) on the Kelvin (K) scale. For most interior lighting applications, warm-white (2700K to 3000K) is preferred.

Expected Life of LEDs

  • Good-quality white LEDs in well-designed fixtures are expected to have a useful life of 30,000 to 50,000 hours or longer.

Stay tuned! Next week we shine light on the energy saving benefits of LED lighting.
