the tiny chips used to illuminate LEDs to lighting hardware

The international accounting firm Ernst & Young LLP contracted Philips Lightolier to provide customized LED fixtures and control systems to replace all the lighting in its 32-floor, 650,000-square-foot office space located near Times Square.

The retrofit, according to Ernst & Young, will save the company about $1 million annually and reduce lighting energy consumption by 54 percent and maintenance cost by 50 percent. The building supports about 5,800 employees and used 6.2 million kilowatt-hours a year before the energy-efficient lighting was installed.

The company already manufactures more efficient conventional light sources and produces incandescent bulbs that are 25 to 33 percent more energy efficient, Eftekhar said.

Lightolier′s 300,000-square-foot corporate headquarters and manufacturing facility at 631 Airport Road employs more than 250 people, and houses a 5,000-square-foot laboratory. The company is completely vertically integrated, Eftekhar said, manufacturing everything from the tiny chips used to illuminate LEDs to lighting hardware for products like track lighting that it invented in the 1960s.
