Our decorations are considered "GREEN" items, Let me explain. All of our decorations are made from quarter inch to half inch powder coated steel. Because of the heavy gauge steel the decoration will last more than twenty times longer than most decorations that are currently on the market. Our decorations are illuminated with LED mini lights that have a average burn life of 125,000 hours compared to traditional mini lights that have a average burn life of 8,000 hours (commercial grade) and 4,000 hours (residential grade). LED lights use 92% less energy than incandescent mini lights.
