In 2008 The General Services Administration began the process of building refurbishment and the modernization of the US Custom House, an historic architectural landmark, in Philadelphia.  Part of the restoration and modernization was the redesign, re-workng and renovation of the exterior lighting.

The design challenge was not to just replicate the existing lighting, but to also improve the lighting visually. Additionally, the intent was to upgrade the lighting systems with new energy efficient technology and control systems.  On-site lighting mock-up demonstrations were used to assist the Owner with understanding the design concepts as well as to select the correct color temperature and color rendering properties of the proposed LED luminaires.  The goal of the demonstration was to ensure that the warmth of the stone and brick are accentuated.  The  building has regained its prominence as nighttime landmark of the Philadelphia skyline.
