If you are a do it yourself-er, this is a great kit.  Typically to get the same effect you have to  and  multiple pieces plus a transformer with the correct voltage capacity.  This kit comes complete and saves a ton of money over buying the pieces separately and you don't have to worry about buying all the right pieces.  This was the only option I could find to work in our open beam kitchen where we needed the fixture to work on the slanted beams.  We strung 2 kits across a very large kitchen. They give you plenty of wire and we had lots left over.  You could do a really huge room with each kit
