These lights are gorgeous! I have to say there is a few issues with these lights you should know. The first is connecting the plug to the line was extremely hard to do. It may feel like you are going to break the prongs but do not worry you won't! Second is the plug and the cord are separate. Not sure how well it will work outside in snow and rain because of the connection there. It seems to me that even with the screw on over the lines that it will not be water proof. Caution is needed for that part of the installation. Perhaps wrapping it up with some water proof electrical tape is a possibility. Other than those two, these lights are extremely beautiful and look amazing when put up. I am also thinking you can link other lights of the same quality together if you need it longer.
