Bought three sets of the 48 Ft strands and installed with no problems. I did use the 16 gauge wire for support and then used small zip ties to fasten the lights to the wire. They are very good quality and look fantastic. I put them on a dimmer and had to use the trick of putting a small floresant bulb in the last string to get them to dim all the way down. Have had them for a couple of months and quite happy.
