On today’s show we will be talking about the LED Light Bulb. In recent years, there's been a movement away from incandescent toward LED bulbs. LEDs, or light-emitting diodes, are a type of bulb that has been around for years, but hasn't necessarily been used for lighting until recently. However, they are something of an improvement on the original bulb design. Light emitting diodes (LED) are made from crystals that may contain materials such as phosphorous in order to produce a distinct color. Overlapping colors, particularly the primary colors of red, blue and green, produce "white" light.
