Bright Idea. There’s really no comparison between the durable, long-life Tetra Contour LED Lighting System and traditional neon. In this exposed neon replacement product, GE Lumination provides a jobsite formable LED system designed to resemble exposed neon in signage, architectural and accent lighting applications. It provides a bright, uniform appearance and a wide viewing angle. For many retailers, restaurants, hotels and other building owners using LED solutions in signage, the use of the cool-to-the-touch Tetra Contour is a natural extension of energy initiatives aimed at retiring less efficient, high-voltage neon systems. Plus, the low-voltage Tetra Contour is up to 40% more energy efficient than neon.
