Red Bluff, Calif. -- Walmart's wind turbine at its distribution center in Red Bluff, Calif., is now operational. The wind turbine is Walmart's first onsite industrial-sized wind turbine and will generate approximately 2,200,000 kilowatt-hours of power, providing up to 20% of the distribution center's annual electricity use. U.S. House Representative Wally Herger joined local officials, as well as Walmart and Foundation Windpower executives, to commemorate the pilot project.

Solid-state lighting took center stage at the SPECS Sustainability session, “LEDs: Perception and Reality.”

Speaker Leigh Savage, national accounts manager, GE Lighting, debunked many of the myths that surround LED lighting. They included:

• LEDs produce no heat at all. FALSE

• LEDs are more efficient than any other light source. NOT NECESSARILY.

• LEDs are still too expensive to use in retail applications. FALSE

New York City -- Solid-state lighting figures prominently in Starbucks’ newly renovated Time Square flagship in New York City. The retailer utilized the services of Focus Lighting, a New York-based architectural lighting design firm, which called upon LED Source, an international supplier of LED lighting.

“LEDs are the most energy-efficient lighting solution on the market,” said Joe Zamore, VP of business development, LED Source, Wellington, Fla., which specializes specializes in full-scale evaluations and retrofits.

Satellite Beach, Fla. -- Lighting Science Group is performing an LED lighting upgrade for Villa, the Philadelphia-based urban-inspired apparel and footwear retailer. Villa estimates the lighting upgrade will pay for itself in one to two years, with energy and maintenance savings continuing to shave costs from its bottom line going forward.

Durham, N.C. -- Cree has acquired Ruud Lighting, a supplier of LED outdoor lighting, at an estimated net cost of approximately $525 million. The companies’ shared focus on best-in-class LED-based systems has led to thousands of LED lighting installations over the past several years, Cree said.

Ruud Lighting will continue to be based in Racine, Wis., and will operate as a subsidiary as part of Cree’s lighting business.

We have all seen the sales people come through the office claiming to have the answer to our lighting energy and efficacy concerns. Virtually every “pitch” will deal with LEDs, and only a rare few will be touting the older fluorescent and the new, almost miniature metal halide lamps.

The new Cole Haan in Manhattan’s SoHo neighborhood combines the brand’s signature craftsmanship with a modern perspective that extends to the lighting. The 1,720-sq.-ft. space is a showcase for the latest in solid-state lighting technology.


“It’s the first specialty store we’ve ever done that is entirely lit with LEDs,” said Lisette Ditters, director retail and hospitality segment, Philips Lighting North America. 


Among other advantages, the LEDs considerably reduce the shop’s lighting-related energy consumption.
