This Super Bowl between the Seahawks and the Patriots will be entirely lit by LED lights in an effort to reduce energy usage by 75%.
The savings come from switching from the standard metal halide lights, which are similar to incandescent lights in your home, to semiconductor based LED lights which are far more efficient, and give off far less heat. We’re very excited to hear this, and to see the initiative. Other stadiums have even gone so far as to install solar panels so they can generate power year round. With such a reduction in energy usage, it might not even be a bad idea for the University of Phoenix Stadium to install solar panels.
It looks like everyone is reading the writing on the wall from the last Super Bowl game where a blackout caused the large Metal Halide lights to cut out during part of the game.
The University of Phoenix Stadium, where the big game is being played, recently upgraded over 780 metal halide fixtures with 44,928 Cree XLamp MK-R LEDs, courtesy of Cree and Ephesus Lighting. And while it sounds like the new setup would draw far more power, it turns out those LED fixtures need a mere 310,000 watts of power to glow, compared to the 1.24 million watts required by the metal halide bulbs.
But power saving isn’t the only benefit to the stadium’s new energy-efficient lighting. The LED fixtures also produce nearly double the illumination of the old metal halide bulbs, and run at full intensity as soon as they’re switched on. If you remember the infamous Super Bowl blackout from a few years ago, it takes almost 20 minutes for metal halide bulbs to warm up and reach their full intensity.
