not to belabor this...but I founds LED strips and power supply separate from z4000...looks like the power supply will power all lights on the strip....once I cut strip to size for what i need for a building...5 or 6? Then what? - Solder wires to the end and connect to the next set of lights at the next building? So it will become a long strip with wires attaching the shorter strips of lights at each building?
