What are LEDs and how do they work?

LED stands for light emitting diode. LED lighting products produce light approximately 90% more efficiently than incandescent light bulbs.


 How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is absorbed into a heat sink.
