LED light bulbs didn’t just pop up overnight, though it may seem like it. In fact, LEDs are a 100 year story in the making, starting in the early part of the 20th century as only a theory. Many dismissed the technology as too complicated or limited to ever have a useful application. Through the contributions of many scientists in many countries, LEDs evolved from being only useful as indicators on TV remotes to being able to light giant screens in Times Square. Check out this infographic, detailing the fascinating history of the LED light bulbs.
LEDs started as just little indicators that couldn’t give off significant light and only came in red or yellow. Now they not only come in a wide range of colors, but they also come in a wide variety of products, such as bug lights or LED flood lights; even Exit Signs can be LED! They are now proving to be the best option in lighting for their high efficiency and low radiation levels. In a world where people are obsessed with cutting costs, LEDs have found their place. But LEDs are still evolving—as the technology gets better, prices will drop, allowing for widespread conversion where once there was hesitation.
