ForceField Energy Contracted to Provide LED Lighting to the Municipality of Uruapan, Mexico; Acquires ESCO Energy Services
SSL Design News Staff

October 21, 2014...Force Field Energy Inc. based in New York, New York USA, announced the signing of an LED lighting agreement with the municipality of Uruapan (“Uruapan”), Mexico. The company expects that the shared savings agreement will generate about $8.4 million in revenue over a ten year period during which the company will supply and install over 15,000 LED streetlights for all of Urupan's municipal roads and highways. In other Force Field Energy news, the company completed the acquisition of ESCO Energy Services Company of Lenox, Massachusetts USA. ESCO offers energy efficiency upgrades and lighting retrofit projects. The ForceField acquired all the outstanding equity in ESCO for total consideration of $7.5 million.

The LED lighting upgrade project in Uruapan will feature a wide array of state of the art LED fixtures including the 15,000 LED-based street lights. The company expects to begin installing the the LED fixtures at the end of 2014 and conclude by Q3 of 2015. ForceField says it will require financing to fulfill this contract and anticipates utilizing financing programs available from the Mexican government. Additionally Uruapan will provide significant assistance in obtaining this project financing due to its strong credit rating within Mexico.

The retrofit project's 10-year energy savings is estimated to be more than 57 million Kwh. Additionally, the company expects the retrofit to save on maintenance for the lighting.

Mexico’s climate change law, which went into effect in late 2012, mandates that the country significantly cut greenhouse gas emissions and increase the use of renewable energy over the next several decades. Mexico intends to cut its greenhouse gas emissions by 30 percent by 2020, and further by 50 percent by 2050. The legislation also calls for 35 percent of Mexico's energy to come from renewable sources by 2024 and requires government agencies to use renewable energy.

“ForceField’s strong commitment in Latin America and its reputation for providing the highes quality LED lighting products and services made them a strong partner for this project,” stated Ing. Aldo Macias Alejandres, the mayor of Uruapan. “We believe this program will create significant value for the municipality, our business community and our citizens through reduced energy and operating costs, lower CO2 emissions, and improved safety as a result of more reliable lighting. Given the scale of this initiative, it was extremely important for us to contract with a company that has demonstrated their ability to achieve the energy savings and reduced carbon output as outlined in their agreements.”

“We are proud the municipality of Uruapan is undertaking a major energy saving initiative that will provide it with significant economic and environmental benefits for years to come,” stated Richard St Julien, ForceField’s executive chairman and president of LED Operations. “As Mexico continues to implement legislation to promote renewable energy to improve efficiency and reduce carbon emissions, we believe that the success of this project will further support our participation in other large scale programs within Mexico. We look forward to working closely with the municipality to ensure the successful implementation of this project over the coming months.”

SSL Design News Staff

October 14, 2014...Novah of Cheshire, UK, has supplied the LED lighting for the recently refurbished concourse and underpass at Liverpool Lime Street train station. The lighting upgrade is part of major renovations that were just completed across the lower level station in an attempt to reduce energy costs and consumption. According to Novah, the project used Novah’s LED T8 tubes. The T8 have a range of options to suit requirements from emergency and microwave tubes to freezer tubes that function successfully in temperatures as low as -40°. In the concourse, the project also employed the company’s LED ceiling panels, which resemble a skylight and can be installed in place of a standard ceiling tile.

Craig Lewis, managing director of Novah, commented, “We’re delighted that Merseyrail selected our LED lamps to complete their upgrade programme at Liverpool Lime Street. We’re at the forefront of LED technology and are extremely confident they will reap huge benefits by introducing LED lighting throughout the new phase of the station. By using Novah’s lamps, not only will they be saving on their energy consumption, the efficiency and durability should also exceed their expectations.”

"We're delighted with the concourse refurbishment around Liverpool Lime Street Station. The quality of the lighting has been significantly improved – offering pedestrians and commuters a safer and more enjoyable experience whilst travelling to and from the railway station,” Mike Jones, project engineer at Merseyrail said. Jones pointed out that, in addition to saving from reduced energy consumption, he would also save on the other costs associated with lighting such as maintenance and lamp replacement. Jones added, “The new revamp of the underpass is now in keeping with work recently undertaken at other locations across the city, ensuring Liverpool is a world-class travel destination for residents and tourists alike."

Periodic Cleaning May Help Reduce Lumen Depreciation in Streetlights, According to DOE Five-Year Follow-up Study
SSL Design News Staff

October 14, 2014...The U.S. Department of Energy did a five-year follow-up report on the installation of lighting on the I-35 Bridge in Minneapolis, Minnesota USA. The report is among the first ever long-term studies of continuously used outdoor LED lighting. The lighting was first installed in 2008. Then in May of 2013 the DOE did a follow up study of the installation.

According to the GATEWAY test results, dirt alone accounted for a 4% decline in lumen output at 5,000 hours and a 12 percent decline at 20,300 hours. The GATEWAY analysis of the data suggests that periodic cleaning of the luminaires may be necessary where road illuminance is critical.

A somewhat troubling result was a decrease in color temperature of about 800K toward the yellow-green region and a decrease in R9. The cause of the color shift was said to be beyond the scope of the project but they said that the nature of the LED color temperature change appeared to be consistent with a change in the phosphor used in the LEDs. They speculated that additional factors could also contribute to the color temperature decline.

After washing the dirt off at about 20,300 hours of operation, the two installed luminaires that had been pretested in 2008 were found to average an 18% decline in light output

The DOE tested two of the LED luminaires prior to installation. A third luminaire that was not installed on the bridge but was tested for 6,000 hours in a laboratory for comparison purposes. The DOE’s GATEWAY program and the Minnesota Department of Transportation (MnDOT) performed follow-up testing on the two installed luminaires in May 2013. The luminaires were tested first in their as-is condition and then again after cleaning.

The GATEWAY project employed a mobile monitoring system designed by the Virginia Tech Transportation Institute (VTTI). At various times between april 2009 and October 2011. MnDOT collected seven sets of measurements.

In November 2009, two luminaires (different from the pretested units) were removed from the installation because the illuminance in the corresponding roadway area was markedly reduced. As part of the GATEWAY project, the DOE tested the removed luminaires in their as-is condition and then retested after cleaning. Most of the issues that the project did encounter were expected due to the early state of technology at the time.

ERCO Lighting Installed in Milan Retail Projects
SSL Design News Staff

October 10, 2014...The lighting designers of Gruppo C14 chose LED lighting from ERCO to illuminate the Kiton Showroom in Milan. Gruppo C14 mounted ERCO LED spotlights at a height of about eight meters. The spotlights fade into the background. Their light emphasizes the products in brilliant colors. Wallwashers cover individual sections of the wall in ambient light adding to the daylight entering through the skylight.

Milan is one of the world’s leading fashion capitals – a look into its local stores reveals which lighting solutions experts in the industry use to ensure optimal staging of their high-end products. Further material on the individual projects can be made available.

The designers used 38W and 28W versions of ERCO's retail spotlight Opton with warm white LED light. The company's 6-degree narrow spot provides up to 3105 lm and can cover the lighting requirements of the Italian menswear fashion label.

ERCO’s spotlight with high lumen packages illuminates the products with high-contrast accent lighting. The system, which is black lacquered and mounted on tracks, becomes a stylishly blends with both historical and contemporary architecture. An exclusive interior made of quality woods, textiles, glass and leather invites shoppers to linger and browse.

ERCO's Optec LED spotlights and Quintessence downlights emphasize the diverse textures of the luxurious materials and the atmosphere of the historic architecture. Some of the other ERCO lighting tools were transformed into sound tools by the Black Out lighting designers, who removed the LED PCBs from a number of spotlights and installed audio system loudspeakers in the luminaire housing.

Discus LED Fixtures from Precision Lighting Integrate Seemlessly with Eco-house's Architecture
SSL Design News Staff

October 3, 2014...Precision Lighting’s Discus LED fixtures complement the use of natural light and the contemporary design of an eco-house built recently in Kent. Nash Baker Architects’ design for the house in Tonbridge, Kent was nominated for the 2014 National Wood Awards. The private residence is designed to be sustainable from its construction materials, which uses locally sourced timber to the home's LED lighting.

The house is located on the grounds of a traditional nineteenth-century house whose owners wanted a sustainable, accessible and contemporary home for their retirement. Nash Baker's design maximized natural light, outlook and privacy.

Lighting designer Tad Trylski specified Precision Lighting's Discus LED fixtures and the company's proprietary lighting track system, Retrac. Both luminaires blend into the architecture so that the artificial lighting appears natural.

The off-white walls offer a suitable backdrop for the British-Danish couple’s eclectic furniture and art. The minimalist design of recessed Retrac system reflects the simple lines of the surrounding architecture. Both the exposed ceilings and the Douglas fir flooring are treated with lime to lighten their finishes and prevent the wood from yellowing over time.

"All spaces and views to and from the property have been channelled for maximum light and privacy, responding to natural sun patterns as well as the clients’ brief to create quieter sanctuaries away from the social areas of the house," said Nash Baker.

"The Precision Lighting fittings were used to highlight specific surfaces and objects, including the worktops and artworks," said architect Simon Baker. "The building is constructed from cross laminated timber with no roof voids in which to insert light fittings, so we looked at track systems that would give us a clean-appearing ceiling and the flexibility to move fittings. In areas, we also had to project light over quite long distances because of the tall ceilings."

"We used Precision Lighting because of their range of aesthetically simple and small fittings, which met our performance criteria. The company itself was a pleasure to work with because of their willingness to help on what was a relatively small domestic project."

Precision Lighting’s Discus 11 and 16 ranges of LED luminaires can be unobtrusively integrated into the surrounding architecture. The ranges come standard in brushed aluminum, white, and black finishes. They can create precise lighting effects including wall washes and projecting sharp images onto surfaces. The Discus 11 and 16 luminaires can also be locked into position in tilt and pan positions so they cannot drift out of focus or be unintentionally moved.

Retrac is a low voltage track lighting system from Precision Lighting. It is rated at 300W and can be recessed into ceilings or walls for general or display lighting. The track can be placed flush to a ceiling with the Retrac luminaires slotting into place after the decoration is complete, or surface mounted. Another mounting option is to have an optional cover strip painted to match the decor.

Precision Lighting points out that Discus is machined from aerospace-grade AL 6063-T6 aluminium, for much more efficient thermal properties than a cast product. According to the company, the high thermal conductivity of the aluminum allows Discus to provide 280-470lm from an extremely compact luminaire while running the LEDs well below their recommended maximum temperature. Additionally, the company's Jack Plug system allows the luminaire to be easily disconnected and reconnected to all of the company's lighting systems.
