From traffic lights to household lamps, LED lights are becoming a popular lighting option. This is due to their energy efficiency and long lifespans. In fact, did you know that by 2030, experts estimate that LEDs will account for approximately three-quarters of all lighting sales?
Here are five fascinating facts about these powerful lights.
The first visible spectrum LED light was invented in 1962.
Yes, you read that right! LEDs have been around for quite a while now—over 50 years. But, because of the costs associated with producing LED lights, they remained cost prohibitive for mainstream use. In fact, a single LED light cost as much as £200 throughout the 1960s.
Eventually, they were developed for commercial applications. They were commonly used as replacements for incandescent and neon indicator lamps, as well as in seven-segment displays.
In the 1970s, however, LED lights began to be commercially produced at more affordable prices, making them a more practical option. Since then, technology has advanced rapidly, prices have declined dramatically, and LED lights have grown tremendously in popularity. For example, between 2011 and 2012, sales of LED replacement bulbs worldwide grew by an impressive 22 percent. At the same time, the price of LED bulbs fell by nearly 40 percent.
LEDs don’t contain any mercury.
A study by the U.S. Office of Energy Efficiency and Renewable Energy found that LEDs have a much smaller environmental impact. Most notably, they don’t contain any mercury—a chemical that can significantly degrade the environment and threatens the health of humans and wildlife alike.
LED lights consume 90 percent less power than standard light bulbs.
You’ve probably heard before that LEDs are incredibly energy efficient. But did you know that they consume 90 percent less energy than incandescent bulbs? That’s because with traditional incandescent light bulbs, 80 percent of the energy is lost as heat and only about 20 percent is converted to light.
With LED lights, the majority of energy is converted into light energy, making LEDs more efficient.
LEDs are predicted to save the world millions of pounds in energy costs.
Did you know that switching your home to LED light bulbs could save you around £240 a year?!
As LED lights become more popular, it will translate into significant energy savings for the country as a whole. In addition to cutting energy costs, it will also save the country millions of metric tons of harmful carbon emissions.
LEDs are operational even in extreme environments.
LEDs work even in extremely cold or extremely warm temperatures, which makes them an ideal option for extreme environments. This isn’t true for other kind if lighting options, such as fluorescent lights, which may be susceptible to extreme cold.
