LED Myths Debunked

There’s a rumor afoot about LED (Light Emitting Diode) streetlights. The American Medical Association (AMA) released a few recommendations in a new policy statement in June 2016 regarding LED streetlights. If not properly understood, you might take some of these recommendations to mean LED streetlights are bad for your community. Read on to uncover a deeper understanding of this beneficial and energy-saving technology as we debunk LEDs myths.

Glare Concerns

The AMA claimed LEDs pose a threat of severe glare, but fails to point out LED street lighting technology has a dimmability that is able to provide the level of illumination needed at any given time – which is nearly impossible for conventional street lighting products. This is just one of the number of distinct advantages over other lighting technologies.

Addressing Human Circadian Rhythmicity

The human circadian rhythm is also called the “body clock.” These terms refer to a 24-hour cycle and pattern that tells our bodies when to eat, sleep, wake, and other regular physiological processes affected by environmental cues, including light.

The AMA suggests LED lights may disrupt the body’s internal body clock through increased blue light waves, however, fails to note there is no inherent difference about the blue light emitted by LEDs. At the same power and wavelength, electromagnetic energy is the same, regardless of source type be it from LED lights or other kinds.

Good for the Earth

In the new policy released by the AMA, they acknowledge the importance of using LED lighting as it “reduces energy consumption and decreases the use of fossil fuels.” Businesses and communities nationwide have attested to the cost and energy savings attributed to LED technology.

It’s important to note that the issue of glare and circadian rhythm are neither new nor restricted to LED technology. While there’s nothing inherently dangerous about LED lighting, it should be used with the same prudence with which we use any other technology. It’s important to direct the light only when and where it’s needed.
