What is LED?

At its most basic, LED stands for Light Emitting Diode. This is light produced using a semiconductor in a process called electroluminescence. Sounds fancy, right? The process is much more efficient than what’s used by traditional incandescent lights and has a much longer lifespan. Its small size and relatively cooler operating temperature means that it can be used in shapes and forms that would have been impossible to light with traditional bulbs.
