With a total of 12 outputs, Light Genie can control an average of 24 light bulbs or 48 or more LEDs. The Genie receiver is broken down into 5 zones. Each zone can independently turn on lights, as well as dim or brighten them. Each zone offers more than 20 different lighting effects including sequential flashing, strobe lighting, fast flicker to produce a fire effect, double strobe, random flash and many others. You can hook up a three bulb traffic light to a zone and another zone can operate a perpendicular traffic light that will automatically cycle in the opposite direction so they can control a 4 way corner.
