Each light strand has more than enough wire to fit any length of celling. There was approx. 6 feet of wire per strand, which is more than enough for most installation. I was not able to coil the extra wire in the mounting plate as there was just too much, so I had to pull the extra though, rewire the connections and then install the light. These steps may have been a little difficult for the average DIY'er to handle. Every other aspect of the light is great; cheap, looks good and my wife loves it.
