Over the last few years, AT&T Inc. re-branding efforts across the country included a redesign of the company logo that necessitated the replacement of 7,000 channel letter signs on more than 6,500 AT&T office buildings and retail locations.
With a switch to an LED lighting system (GE Lumination’s Tetra), AT&T is expected to save more than 5.8 million kWh and eliminate 3,500 metric tons of carbon dioxide annually.
In total, approximately 2.6 million LEDs replaced both the high-voltage, high-maintenance neon that is often used in small-building signs and less-efficient linear fluorescent lighting, which performs less favorably than LEDs in cold climates.
