Available in two designs, Hummer and Military stylings, you can tell that the Fan-Atic has a very ruggid design to it. The metal faceplate is entire CNC Milled from solid steel. My initial impressions of handling the device proved to back up this thought. It's heavy; and it's certainly designed to take a beating. Lamptron chose a five channel design for this baybus, offering one more channel than the average baybus provides. All channel switching is done with a ridgid toggle switch. The middle position is off, down provides the full 12 Volts to the channel and up provides 7 Volts to the channel. The LED lighting action comes into play when the device is on and will illuminate that channel blue when 12 Volts is selected and red when 7 Volts is selected. No lighting is in effect when the channel is off. I still find myself questioning why it wasn't the other way around, to me it seems like 12V should be up and 7V should be down.
