LED lighting, with its energy efficiency, low maintenance requirements, and therefore low lifetime cost, is replacing more traditional forms of lighting in virtually all types of applications. Lighting Science Group Corp., a company based in Satellite Beach, Florida, has developed LED street lights powered by wind and solar energy that can be installed in virtually any place in the world and don’t need to be connected to the electrical grid.
In a press release in August 2010, Lighting Science Group announced that its PROLIFIC DC LED street lights are being installed to light a 23-kilometre elevated highway in Mexico City. The LED street lights are integrated with the solar photovoltaic system, use no energy from the electrical grid and are practically maintenance free. According to Lighting Science Group, the street lights are at least 50 percent more energy efficient, increase the light level with a more uniform distribution, and will save thousands of dollars in energy and maintenance costs over the life of the light fixtures. The company had previously completed the installation of LED street lights in the Vista Verde Country Club in Tehuacan, Puebla, Mexico.
In another press release in August, 2010, Lighting Science Group announced that it had installed its LED street lights in Banyeres de Mariola Alicante, Spain. The company’s PROLIFIC series of LED lights have been tested by an independent laboratory and approved by the U.S. Department of Energy’s CALiPER program. These lights eliminate the need for re-lamping and re-ballasting HID street lights and use direct line wiring instead of starters or capacitors, which reduces the need for traditional maintenance.
As reported by the LEDs Magazine in March, 2010, Lighting Science Group entered into an agreement with Senergy USA to help cities, counties and towns across the U.S. install more efficient lighting systems that help the environment and save money. Under this agreement, Senergy will use Lighting Science Group’s PROLIFIC series street LED lighting to replace inefficient, high pressure sodium street lights. The companies indicate that they are working on a half dozen pilot programs across the county that represent more than 200,000 street lights and claim that the pilot programs have show up to a 67 percent reduction in energy consumption.
Realizing that communities across the country are facing severe financial constraints, Senergy USA has developed a program to help the communities with the upfront cost in order to save money on energy. Senergy works with the community to perform an analysis of its lighting needs to determine the amount of saving it can provide through energy efficiency. Then Senergy provides all the capital expenditures necessary, at its own cost, in order to convert the traditional lighting system into a more efficient system using LED lighting. Senergy indicates that typically it enters into an 11-year contract with the community to cover the costs of its lighting systems, including installation, maintenance and energy costs.
