LEDs: A need for illumination standards
July 6, 2018
In recent years, many incredible innovations have reshaped the sign industry, but some of these changes have produced new challenges that need to be addressed. Lighting, in particular, is among the key areas where technological developments have caused their own difficulties. Lighting is the foundation of the modern sign industry. When the first major trade organization, the National Electric Sign Association (NESA), was established in 1944, it was built around a relatively small group of lighting suppliers that kept tight control over manufacturing standards. Over time, as NESA expanded in scope and became the International Sign Association (ISA), there was a concurrent expansion in signmaking materials and technologies, which made it more difficult to maintain consistency. The replacement of neon lighting with LEDs posed the greatest challenge of all.
