project LIGHTING New induction high-bays illuminate the concourses under the stadium’s end-zone seats.
Historic Lambeau Field, home of the Green Bay Packers, is getting an energy-efficient upgrade using induction-lamp technology.

ne of the National Football League’s most revered stadiums, Lambeau Field in Green Bay, WI, home of the Green Bay Packers, features the only true retro look in the entire league. Recently the structure has been transformed from a football stadium that fans used only 10 days during the season to a Packers cultural center that can be enjoyed throughout the year. Lambeau Field managers also implemented a major lighting overhaul. Powrtek Engineering Inc., an electrical-engineering firm based in Waukesha, WI, searched for a solution that would meet building codes and decrease maintenance costs. The final choice: 200-W induction high-bay fixtures from EverLast Lighting, Jackson, MI. Designed to improve safety and visibility and meet emergency regulations, the induction high-bays offer 100,000 hours of lamp life and an efficacy of 85 lumens/W, making the technology very energy efficient and cost effective. The concourses under the south end zone received 71 induction high bays to supplement existing lighting. Several hundred additional induction fixtures will

be installed throughout the stadium this winter. “The manufacturer provided a color temperature that we needed as a custom blend at 3,000 K,” said Greg Sadowski, president of Powrtek Engineering. “Additionally, there were strict emergency-lighting specifications that we had to meet. The fixture had to be able to turn on within 10 seconds in the event of an outage. The induction fixtures are doing double duty: They possess the required color rendition in
Induction technology is an electrode-less lamp that has been around for more than 100 years. Due to recent advancements, it has become an effective lighting option for roadways, parking structures, municipalities, warehouses, and largescale facilities. With no electrodes, the lamp relies on the fundamental principles of gas discharge and electromagnetic induction to produce light. Based on these principles, light is generated using gas discharged through magnetism. Rings with magnetic coils create an electromagnetic field
addition to the instant-on feature. “HID [high-intensity-discharge lamps] cannot provide the specifications required,” Sandowski added. “Furthermore, with induction’s 100,000-hour lifetime on their fixtures, it was an easy decision. We would’ve been lucky to get 20,000 hours out of any other fixtures. Once we took the warranty and the lower maintenance costs into consideration, we knew that we wanted to go with induction.”
