money,” said Antonio Sousa, Osram Opto Semiconductors Portugal.


The project began with a detailed analysis of the retail chain’s lighting requirements. Based on the results, Arquiled developed a luminaire concept to meet the special needs of supermarkets. LED lighting not only offers the advantage of a long service life and the associated low maintenance costs, but is also ideal for direct product illumination.


LEDs generally emit very little thermal energy and do not heat up the objects they are illuminating. They can hence be positioned closer to products without damaging them.


Three Arquiled modules are to be used at the Jerónimo Martins in Tavira: the Arquiway, a module comprising 4 Oslon SSL LEDs; the Arquistore, with 72 Oslon SSL LEDs per luminaire; and finally, Arquishelf luminaires, which will provide special shelf lighting with 56 Oslon SSL LEDs, illuminating products in the ideal colour temperature and displaying them at their very best.


North Carolina Water Reclamation Facility chooses Cree LEDs


The 45 Cree THE EDGE LED area luminaires are providing significant reductions in energy usage and costs while dramatically improving visibility and overall safety


As part of a city-wide goal to reduce energy usage and improve night time visibility and overall facility safety, the South Durham Water Reclamation Facility installed energy-efficient LED lighting from Cree.


The new Cree lighting simultaneously addresses the facility’s competing exterior lighting requirements – the need to improve safety and light levels and the need to reduce


energy usage and maintenance costs.


“This lighting project delivers multiple benefits,” said Joel Reitzer, director of the City’s General Services Department. “Not only were we able to increase visibility and provide our workers with a safer, more productive work environment, but we also reduced our energy consumption by nearly 64 percent for the fixtures that were replaced with the new Cree lighting. It really is a ‘win-win’ for the City’s bottom line and ultimately, Durham’s environment.”


The South Durham Water Reclamation project was part of an overall effort by General Services, Community Development, Water Management and the City-County Sustainability Office to reduce energy use in the City.


Forty-five Cree THE EDGE LED area luminaires were installed in the processing area and at the front gate of the South Durham Water Reclamation Facility. The Durham facility operates 24/7 and monitoring of the system often occurs at night.


“The City anticipates significant maintenance savings in both material and labour with the new Cree lighting,” Reitzer continued. “After installing Cree LED lighting, we are realising a significant reduction in energy usage and savings in energy costs while dramatically improving visibility and overall safety. The installation and lighting costs are short-term, but the energy savings, lower maintenance costs and safety benefits will endure.”


“Facilities with 24/7 operation have unique lighting requirements,” said Al Safarikas, director marketing, Cree lighting. “Cree is committed to developing innovative LED lighting solutions that address the diverse needs of our growing customer base. For the South Durham Water Reclamation Facility, Cree provides energy savings, reduced maintenance, and the illumination needed for night time productivity and safety.”
