news review Cree lights up Denny’s restaurants
DENNY’S Corporation, one of America’s largest full-service family restaurant chain, has chosen energy-efficient LED lights from Cree as the preferred lighting standard for all its new and remodelled stores across the United States. Cree’s LR6 six-inch downlights are being specified in various applications, including dining areas and rest rooms in all newly constructed and converted facilities.
“We evaluated numerous LED light fixtures from a variety of manufacturers to ensure that we chose the best possible product and partner for this major lighting specification,” explained Mitch Riese, corporate architect, senior manager of design & construction, Denny’s. “With the Cree LR6 fixture, we found the best value for our money, helping us deliver warm light, while reducing energy consumption and maintenance requirements.”
Pete LaBarre, a Denny’s franchisee in Colorado Springs, Colo., is already seeing extensive savings since converting to LED lighting. LaBarre has installed more than
400 Cree LR6 downlights in the dining rooms of his five restaurants, a move that has saved him around $15,500 per year in energy costs alone. Impressed with the energy and maintenance savings from installing LR6 downlights in his dining rooms, LaBarre has decided to use the six- inch LED downlights in a variety of other applications. Currently he has replaced 500 fluorescent bulbs and tubes with 200 Cree LR6 fixtures, illuminating the perimeter of each restaurant.
“Our lights stay on all the time, so we did a watt comparison of what we had in place before the LR6 downlights,” said LaBarre. “We found that we used 6,000 kilowatt
hours less per month in the store that had the Cree fixtures versus the store that had the fluorescent lighting,” he said.
Another early LED lighting devotee is Joey Terrell, a Denny’s franchisee in Illinois. In 2009, Terrell opened his second restaurant in Joliet, a suburb of Chicago. Built according to Leadership in Energy and Environmental Design (LEED) Gold standards, the Joliet Denny’s includes a combination of natural lighting and Cree LR6 LED downlights to reduce the restaurant’s lighting load.
According to Terrell, this lighting design reduced utility costs by 83% and his electricity bill is now around $1,000 a month instead of the expected $2,100 a month based on the average costs for his location.
“Restaurants use 285% more utilities than the average commercial building,” said Terrell. “The easiest way to reduce costs and improve energy-efficiency is to switch from traditional fluorescents to daylighting and LEDs, and that’s what we did.”
Roled Opto and FLS Light Up Pearl River in Guangzhou
FUTURE LIGHTING SOLUTIONS (FLS) has announced that it is illuminating the Pearl River in Guangzhou, with 700,000 Lumiled’s LUXEON Rebel LEDs. The city of Guangzhou recently completed a project to illuminate the banks of the Pearl River as part of their welcome ceremony for the Asian Games and to celebrate the successful convening of the Games in Guangzhou. This project was an open tender called for by the Guangzhou Municipal Government, which was awarded to Roled Opto Electronics (Shanghai).
The project objectives were to create a green, energy efficient, environmentally friendly and high-tech Asian Games. The Guangzhou Municipal Government’s requirements called for a professional LED manufacturer, with reliable pre and post sales support.
Roled Opto Electronics (Shanghai). was the main designer of the solution for this project. The deployment involved around 30,000 LED light fixtures and 700,000
LUXEON Rebel LEDs. China Construction Eighth Engineering Division (Guangzhou Subsidiary) was responsible for installation.
LUXEON Rebel LEDs were selected based on their luminous flux, color temperature, color index and reliability of the LEDs. With the help of Future Lighting Solutions (FLS) and the use of their Usable Light Tool (ULT), LEDs best suited for this project were selected. Roled also made use of QLED Thermal simulation software to optimize their heat dissipation system.
With the support of the Lighting Resource Centre (LRC), Roled was also able to test and evaluate optical lenses, and deployed National Semiconductors’ buck regulator as part of the solution. FLS and Roled have always based their partnership on a philosophy of strategic co-operation. With assistance provided by FLS and their LRC, Roled Opto Electronics selected suitable LED models and optical lenses, which were able to resolve a number of issues related to lighting efficiency and light distribution.

They also had to keep in mind that the Guangzhou Municipal Government expected an ROI within 3 years, and hence devised a solution based on LED light fixtures as this technology delivers more than 60% savings in terms of energy consumption, and reduces CO2 emissions by 80%. These factors greatly shorten time taken to actualize the return on investment. At the same time, FLS also provided significant support in terms of price, availability and supply continuity, which enabled Roled to complete the project according to schedule.
Wang Shiming, GM at Roled Opto Electronics’ adds, “During the Guangzhou Asian Games, images along the banks of the Pearl River that were broadcast captured the essence of the dazzling skyline. In particular, images of the White Swan Hotel were displayed repeatedly during the opening ceremony, which effectively illustrated how the LUXEON Rebel LEDs were able to deliver based on the requirements of the business owner and the Guangzhou Municpal Government.”
