Pedestrian and Parking Lot Area Lighting


63 BetaLED® area luminaires

  • 41 area round luminaires with Type II optics
  • 22 area square luminaires with Type III optics


  • Improved light levels
  • Reduced energy use
  • Virtually zero maintenance with no relamping necessary
  • Use of ARRA funding

ARRA-funded LED retrofit reduces energy, improves lighting performance

The Minneapolis Public Housing Authority (MPHA) manages and maintains nearly 6,000 housing units in Minneapolis, including 753 scattered sites (individual homes), 184 family development units, and almost 5,000 apartments in 41 high rises. Providing for more than 10,000 residents makes the agency a significant consumer of utilities. In fact, the enormous quantity of electricity and water used each year by MPHA residents is enough to supply a small city.

Six train station platforms spanning 40 miles from downtown Minneapolis to Big Lake, Minn. are illuminated with BetaLED round area luminaires on 15-foot spider mount posts.The three-light bar luminaires with Type V distribution at 350mA achieve the project criteria of providing two foot candles minimum illumination at the edge of the platform tactile strip for safe visibility.

“Saving energy is critical to the effort of preserving these vital resources located in Minneapolis. MPHA’s preservation process includes pioneering storm water runoff mitigation methods, installing LED lighting, new appliances and implementing cutting-edge ‘green’ initiatives, such as utilizing solar tubes,” said Emilio Bettaglio, MPHA Deputy Executive Director.“These improvements enable MPHA to make the 20th century structures remain affordable homes for the 21st century,” he stated.

As part of its green initiative to reduce energy use,MPHA retrofit exterior campus lighting at The Cedars, a large high rise complex that houses 500 residents, predominantly senior citizens. One 25-story and three 10-story buildings share common green space with walking paths and parking lots on a seven-acre site at Cedar Avenue and 6th Street.

Funding from the American Recovery and Reinvestment Act (ARRA) was used to replace high pressure sodium and metal halide light fixtures with energy efficient LED luminaires. MPHA received $18.2 million in ARRA funds which were added to MPHA’s Capital Fund Formula Grant. MPHA allocated $3.2 million of these funds to the Cedars Improvement Project. Approximately 97-percent of the MPHA’s funding is provided through federal subsidies and rents.The remaining three-percent is provided by the City of Minneapolis.

MP Consultants, an engineering firm based in Plymouth, Minn. specified 63 BetaLED area luminaires installed on 30-foot poles with 3-foot foundations.The retrofit provides a reduction in energy use, virtually zero maintenance with no relamping necessary, and dramatically improved illumination.According to Jerry Welf, MPHA project manager, residents at The Cedars say they feel safer walking through parking lots and pathways after dark since the BetaLED luminaires were installed.

“The new lighting looks incredible.There’s a significant contrast to light in the surrounding areas that looks orange by comparison,” said Welf. “Installing an energy efficient lighting system was an important component of the retrofit project and the improved lighting has made a difference for our residents.”

The project went beyond a lighting installation and included a $5 million hard surfaces site reconstruction to parking lots and walkways.Two-thirds of the project was completed in 2009 with the last third of the installation completed in summer 2010. MPHA also successfully competed for and received approximately $32 million for three additional initiatives:

  • 48 unit Memory Care Development
  • 69,000 square foot Senior Health and Wellness Center
  • Scattered Site ‘Green Initiative’ for making significant energy improvements to MPHA’s 733 Scattered Site Resident Homes
