LED lighting differs from incandescent and compact fluorescent lighting in several ways. When properly designed, LED lighting solutions can offer higher efficiency, increased durability, and significantly longer life than traditional light sources. Traditional lighting products leverage standard bulb shapes and historical base types (Example: A19 with E26 medium base). LED lighting products, on the other hand, incorporate custom light sources and application-specific electronics. Compared to the traditional lighting technologies of Incandescent (light is produced by heating a tungsten wire) and Compact Fluorescent (light is produced by exciting phosphors with the emission of mercury), LEDs produce visible light by passing current through a solid state diode. The solid state diode converts electrical energy into photons, and the color of the photon is defined by the selection of materials used to fabricate the diode. For example, red LEDs are typically produced with an AlInGaP diode (Aluminum/ Gallium/Indium/Phosphide), and green LEDs are produced with an InGaN diode (Indium/Gallium/ Nitride).
