Neonetics neon signs have a warm mesmerizing glow, and are powered by industrial strength transformers, which operate silently and more efficiently than incandescent bulbs. Neonetics Premium Junior Neon Signs feature multi-colored, hand blown neon tubing, and the entire sign is supported by a black finished metal grid. The Neonetics High Life Neon Sign measures 18 inches by 14 inches, and features beautiful green and white real glass neon tubes. The sign can be hung against a wall or window; they can even sit on a shelf. All you do is hang it up and plug it in – no assembly or special wiring required. Give your home the fabulous glow of real neon by Neonetics!
