Case of 12.  These items each feature 25 C-7 green lights on green wire.  They are anything but standard light sets.  In fact, do not be surprised if you cannot find these anywhere else!  All you need to connect these strands is one power cord, sold separately, to power them.  From there you can use the end-to-end connectors to connect up to a previously unheard of 125 strands together to create a phenomenal 3000 feet of light!  If that is not enough, although resembling traditional Christmas lights, the lights on these strands utilize advanced LED technology, which means they are more energy efficient and have cool burning lights that do not get hot when lit.  They are also indestructible and will never burn out!  There is no need to worry about the hassle of replacing bulbs on these strands EVER.  These truly are the Christmas lights of the future, but fortunately they are here today!  They each stretch approximately 25 feet long and feature a special 12 inch spacing between bulbs, which is more spacing than our usual light sets.  This makes them useable in many other applications that require additional length.  They each have an 8 inch lead cord as well as an 8 inch end cord.  Imagine decorating the entire outside of your home with just one plug!  Hang it on your Christmas tree, around your banister, over your doorway, or anywhere else that can use a touch of the soothing glow these strands emit. They are great not only for Christmas, but for Halloween and Saint Patricks Day as well.  UL listed for indoor and outdoor use.  Please be sure to purchase at least one commercial grade cord, item number CNAPCORD1G, to connect either 1 or 125 LED light strings together in a straight line.
