Light-emitting diodes (LEDs) have been around for more than 40 years, but only recent innovations and technological advances have made them bright enough to become useful for commercial settings. Today’s LEDs can sustain high light output in demanding operating environments.

While light-emitting diodes (LEDs) have become a popular technology for sign illumination, due to their efficiency, longevity and performance, they have not yet succeeded other types of light sources in all mainstream applications. Box signs, for example, are still waiting for LEDs to become the new standard.
