LED stands for light emitting diode. That doesn’t mean much to you, but it will in a second. LED lighting products work completely differently than conventional light bulbs. By passing an electrical current through a microchip, the energy source illuminates tiny light sources we call LEDs (or light emitting diodes) resulting in visible light. These kinds of lights are directional light sources, meaning they emit light in a specific direction unlike incandescent or CFL bulbs, which emit light every which way. This allows an LED to emit light much more efficiently than a conventional bulb, but is also far more difficult to produce. Usually, you’ll see coloured LEDs in signal lights, computer parts and inside older televisions. In order to produce the white light of a lightbulb, different coloured LED lights are combined and covered with a phosphor material which converts the light into a neutral, white light. See? It’s simple.
