Created to resemble and replace exposed neon, the weather-resistant Tetra contour LED lighting system can be used in a variety of signage, architectural, and accent lighting applications. Tetra, made up of an optically diffuse extruded-plastic light guide and a GELcore LED light engine, will have the look of neon and many of its advantages-a long life span, low-voltage operation, and easy installation and maintenance-while providing a bright uniform appearance with a wide viewing angle.
