The practical advantage of this technology, for the control of our RGBW "PLC" colour changing lamps, is in the realisation or adaptation of the electrical installation. In a new installation, all that is needed to power the lamps is a simple two-wire cable, simplifying the connections and allowing a larger cable section than would be necessary if we had to add the data conductors.
In a traditional existing installation, there is no need to change the existing cables because they already have two wires.
