Lightology's base is a 20,000-square-foot showroom designed from the ground up to be the premier showcase for contemporary lighting in North America. Visitors encounter a stunning, glass-enclosed, three-story modern space that flows around a central atrium with product-filled catwalks and permanent exhibits on light color, temperature and the history of electric lighting. In December 2001, the first floor of Lightology opened to the public. Already the largest U.S. distributor of high-quality contemporary lighting, the building's four floors are now completely developed to serve the specialty needs of architects, designers, contractors and other professionals. Topping things off is a lush roof garden, providing dramatic city views in a stunning setting for meetings and events.
