Norman Foster has made his long-delayed New York debut with a prismatic glass
office tower that enlivens the congested skyline of mid Manhattan and reunites the scattered offices of the Hearst publishing corporation.
"We like the prismatic glass
reflector on the Retailer luminaire because we feel it is more attractive than an acrylic reflector," says Erdman.
The high mast system installed includes cutoff optics and a prismatic glass
reflector, which is nine to 14 percent more efficient than enclosed aluminum reflector systems, translating into fewer fixtures and lower energy bills.
The lighting system installed is a combination of prismatic glass
and fluorescent fixtures from Holophane Corp., Newark, OH, and its Metal Optics subsidiary.
Features such as durable prismatic glass
and acrylic optics control light distribution and provide fixture placement flexibility.

Daniel Libeskind, who recalls his own shipside view of downtown New York as a teenage immigrant, was so impressed by the survival of the towers' slurry walls that he retained them and sunk the footprints below a cluster of prismatic glass
buildings, the spire of the tallest housing an interior forest.
From the exterior, the prismatic glass
box shows off its structure with exposed crossed steel beams behind the curtain wall system.
The luminaires have a translucent prismatic glass
diffuser, in three sizes, internally coloured in white, yellow, blue or grey.
