Over the recent years, the use of LED lights has been increasing—all thanks to its efficient characteristics such as its long life span and its resistance to breakage. LEDs have been used in lighting bulbs, LED signs, TVs, display cases and even, in toys. But think you know everything about LED lights? Well, here are some of the 7 interesting facts about them that you might have not heard yet: #1 LED or light-emitting diodes are actually a type of solid-state lighting that uses a semiconductor to convert electricity into light. Such process makes it seven times more energy efficient than conventional incandescent lights and cut energy use by roughly 80 percent. #2 Unlike incandescent bulbs, LEDs uses energy far more efficiently with little wasted heat. That's why compare to the former, LED lights doesn't heat up much. #3 Quality LED bulbs can have a long lifespan of about 25,000 hours —which means they last more than 25 times longer than other tradition
