There are many advantages to using intelligent LED lighting, such as energy savings for big time corporations, safer vision for luxury vehicles and a higher quality playing field for professional sports. A large impact LED lighting has is on all major sports arenas and stadiums. We will look into which stadiums, teams and sports decide to embrace the power and advantages of intelligent LED lighting.
A very informative and detailed article is available at The Washington Post. Giving full details on why sports arenas have made the decision to install LED lighting to stadiums across the globe. We give full credit to The Washington Post for writing all major details on this topic.
For years now, all sports stadiums have used metal halide lights to illuminate playing fields and surfaces. However, today arenas are turning to LED lights, which have already made inroads in everything from city street lights to Christmas lights.
Back in 2012 when the San Francisco 49ers were investigating light options for Levi’s Stadium, LED lighting was still not a very popular option for many sports teams. According to a 49ers spokesman, broadcast networks raised concerns about the readiness of LED lights for use in a major stadium. While the team looked at a few LED prototypes, it ultimately opted for the safe and traditional metal halide lights to illuminate the field.
Since then, many sports arena have changed their minds on LED lighting. The NFL’s Houston Texans and Arizona Cardinals have switched to LEDs for their season.
“The payback was quite attractive in terms of the energy savings, not just for our events but in all events that happen out here,” Houston Texans president Jamey Rootes said. “You add to it the softer benefits of the quality of the presentation on television, the quality of the presentation for the fans in the stadium, a more vibrant stadium experience.”
Rootes said he hadn’t heard any concerns about LED lights affecting the quality of a TV broadcast. Ephesus Lighting chief technology officer Joe Casper mentioned that a Fox broadcasting crew sent to certify his company’s work at Cardinals’ stadium described it as “the best lit stadium they’ve ever seen.”
An ESPN spokeswoman pointed out a perk of LED lights — because they don’t necessarily flicker, viewers won’t be distracted by flashing while watching slow-motion replays. And while metal halide lights need time to warm up, LEDs turn on immediately.
The Carolina Hurricanes also installed LED stadium lights this off season, becoming the second NHL team after the Montreal Canadians.
“These LED lights will outlast the rest of the building,” said Dave Olsen, the general manager of PNC Arena. “We’ll get a solid 20-plus years of life without having to do any maintenance to them at all. That’s the real key, I don’t have to relamp every three to five years.” He also said the clean white LED light makes for a better in-house experience given how it reflects off the white ice.
LED lights take much longer to age, while metal halide lights take on a reddish tinge and become less bright over the years.
The lights in Houston and North Carolina have been installed by Musco, which lights 2,000 sports fields a year. In 2007 they relit the White House, being the first time using LED bulbs.
“There’s a lot of interest. The core technology has continued to improve and the costs have come down to the point where it is becoming much more applicable today than it was even a year ago, even two years ago,” said Jeff Rogers, its vice president of developmental sales. “There’s more interest and there’s more discussion about it.”
The playing field is actually brighter now at the University of Phoenix Stadium — home to the aforementioned Arizona Cardinals — after 780 metal halide light fixtures were replaced with 312 LED light fixtures.
Colleges such as Arizona State and Notre Dame have also switched to LED lights on their basketball courts.
Depending on the project, the significance of energy savings will vary. In San Francisco, LED lights were used for 40 percent of lights inside and outside the stadium. A spokesman expects energy savings of 15 to 20 percent. Olsen didn’t want to quote a number on his savings in North Carolina until seeing a year of utility bills. Musco says the lights in Houston will save 60 percent over the lights they’re replacing.
Houston’s lights were installed in partnership with NRG Energy, which has installed everything from wind turbines to solar panels at other NFL stadiums, including FedEx Field. It hopes that exposure will encourage consumers to think about nontraditional energy options.
“Our message is the power to be free. People have sustainable choices that they can make that haven’t been available for them in the past,” said Sicily Dickenson, NRG Energy’s chief marketing officer.
No Major League Baseball stadiums have made the switch to LED lights yet, but Ephesus Lighting said it’s in discussion with two teams.
Ephesus first installed LED lights in Syracuse’s War Memorial Arena in 2012. Since then, its done over 30 arenas around the country.
