National LED Light Day | October 7
(Last Updated On: November 9, 2022)


October 7th may be an unusually illuminating day considering it is National LED Light Day.


We are all born as incredible detectors of light. We intuitively notice differences in color and brightness. And lighting professionals know that much of human sensation is visual. People respond emotionally to light and color, using its consistency to draw us in, like moths to a glowing light. The power of LED lighting affects all of us in emotional, economic, and environmental ways, too.


Unlike other light sources, LEDs can create a more appealing display for a variety of environments. Let’s say you drive by two gas stations. Station A is illuminated throughout by bright white LED lights, while Station B’s illumination varies from yellow to white and one panel is dim. You will likely go to Station A because its color consistency feels comforting, clean, secure, and high-quality. You may not even be conscious of that decision.


LED lights help save on our energy costs. The low power consumption, high reliability, and long lifespan allow us to realize significant energy savings. They also reduce maintenance over the lifetime of an LED fixture.


The fewer LED bulbs changed means there are fewer bulbs thrown away. LED bulbs also have a much smaller impact on the environment than other light sources. Furthermore, because LEDs use electricity very efficiently, greenhouse gas emissions are reduced.


Explore the many benefits of LED lighting. Visit a showroom near you or share your favorite ways to use LED lighting. Show off your favorite displays of LED lighting. Whether it’s at work or home, share your personal favorites. Use #NationalLEDLightDay to share on social media.


On October 7, 2014, Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura received the Nobel Prize in Physics for the development of blue light-emitting diodes. To understand why this was a Nobel-worthy achievement, we must know the history of LED lighting.

The earliest LEDs created in the late 1950s and early 1960s produced only a red-colored light. Slowly researchers developed other colors, but blue stumped them. Its shorter wavelength proved harder to reproduce. With Akasaki, Amano, and Nakamura’s invention, white LEDs were now possible.

The Registrar at National Day Calendar approved the day in 2016.


Q. Do LED lights come in a solar energy model?
A. Yes. LED lighting is available with solar charging capacity for a variety of uses.

Q. Do manufacturers make LED grow lights for house plants?
A. Yes. LED grow lights for plants come in several different designs to meet your plant growing needs.

Q.What is the average lifespan of an LED bulb?
A. Depending on the manufacturer, LED bulbs can last between 35,000 to 50,000 hours. Compare that to an incandescent bulb at up to 2,000 hours.


October 7 Celebrated History


The first commercial railway opens. Granite Railway hauled granite from quarries in Quincy, MA to the Bunker Hill Monument. Horses, not steam engines, hauled the granite destined for the Bunker Hill Monument. Gridley Bryant designed the innovative system and portions of the four-mile route remained in use until the 1960s.


Georgia Tech and Cumberland University of Tennessee played the highest-scoring game in American football history. After a record 32 touchdowns by Georgia Tech the final score was 222 to 0.


The far side of the moon gets its own photoshoot when NASA’s Luna 3 takes its first photos. It’s the first time Earthlings get to view that side of the Moon. Since the Moon’s rotation is so slow, the same side always faces the Earth.


Toni Morrison receives the Nobel Prize in Literature. The award-winning author of the Beloved Trilogy brings depth to her characters and sheds light on the less than savory aspects of humanity. Some of her other works include the Song of Solomon, Tar Baby, and God Help the Child.


Rupert Murdoch and Roger Ailes begin broadcasting the Fox News Channel.


Space Shuttle Atlantis lifts of from NASA’s Kennedy Space Center on mission STS-112 carrying payloads to further equip the International Space Station.


The first predicted near-Earth asteroid strikes the Earth’s atmosphere above northern Sudan. While small asteroids like the 2008 TC3 enter the atmosphere throughout the year, this one was identified the day before by Richard Kowalski.
