Instead of metallic halides and high-pressure sodium lamps, most parking lots now utilize light fixtures powered by Light Emitting Diodes. Unlike typical lamps, LED floodlights and other similar parking lot lighting systems almost look like computer chips. When connected to a specific power source, an LED diode can generate a lot of luminosity. In addition, these diodes focus light exclusively in one direction rather than HID lamps emitting light in all directions.
