These 8 puck light sets nestle perfectly into the round, molded areas in the top of the xStream float and are a great way to illuminate the new xStream fountain effectively and economically (both with purchase price and electrical costs). Each set of puck lights includes the ring of 8 pucks with dual lock fasteners to attach to the float, along with the standard 50', 100', 150', or 200' power cord options. They simply plug into the standard Kasco controllers. These new lights carry a 1 year warranty.
