LED lighting has come a long way since their invention in 1962. By the early 1970s, LED lights were popping up in digital watches all over the country. Shortly thereafter, they became a fixture in engineering kits, with research engineers using LED lights as front panel indicators, however dim they were in comparison to incandescent bulbs.
Eventually, the red LED lights were joined by green and amber in the mid-1980s, with blue LED lights becoming available in the early 1990s. At this point, they had brightened up considerably, becoming the new standard for front panel indicators in everything from microwaves to audio amplifiers.
The Nobel Prize for physics was actually awarded this year for a blue LED light that has the potential to save the world. The blue light has become the standard for television screens and ceiling lamps.
However, blue LED lights have been too stark to provide any semblance of natural light indoors. There have been tries in the past decade, but not until 2012 and the invention of the 2700K LED bulb did LEDs succeed in creating what is now called a “warm white” light.
In 2014, LED lights are finally becoming the public standard. They are replacing halogen and incandescent lighting in traffic lights, flashlights, street lighting, and billboards. In the public sector, this makes lighting 13% more efficient than previous methods. And in specialized areas like the medical and research sectors, that number is nearly doubled.
