You’ve all heard the buzz about LEDs recently. In truth, light-emitting diodes have been around since the 1960s. Over the last five years, the price of these diodes has come down significantly and while there is certainly room for improvement, the technology has become more reliable. We are seeing LEDs used for lighting in a multitude of applications including everything from street lights, to freezer lighting, to the taillights of your automobile. As the cost of the diodes decline the advantages over other light sources including lower energy consumption, longer lifetime, durability, smaller size, and faster switching have led to greater use in lighting applications.
