AT&T Implements LED Lighting to Improve Eco Efficiency

As part of its rebranding efforts over the last few years, AT&T replaced over 7,000 channel letter signs on more than 6,500 AT&T office buildings and retail locations. In doing so, AT&T has been installing the energy-efficient, long-life GE Tetra LED lighting system. The company calculates that it will save more than 5.8 million kilowatt hours of electricity year and eliminate 3,500 metric tons of carbon dioxide annually -- the equivalent of planting more than 950 acres of trees. The GE LEDs are up to 80 percent more energy efficient than commonly used neon.
