A section comprising one fiftieth of the total canopy equals the size of the world's current largest electric sign. Originally, nearly 2.1 million incandescent lights were housed in the canopy. With the completion of the $17 million upgrade, more than 12 million LED lamps illuminate the overhead canopy. The new LED upgrade was designed and engineered by LG Electronics, who is also the primary corporate sponsor of the canopy. Within the canopy itself are 220 speakers powered by 550,000 watts of amplification.
