Grenald Waldron Associates (GWA) is a full service architectural lighting design firm based in Philadelphia and with offices in Shanghai and Beirut. 

GWA’s lighting philosophy is based upon two keys elements.  First, light should effectively illuminate a built environment in a way that is true to the intended architectural space and form.  Secondly, light will effect a behavioral response in all living things and should be applied in a way which exploits this fact. 

GWA approaches each project as if it is a unique new opportunity, but will utilize many years of lighting experience and industry relationships.  This offers our clients fresh solutions honed by a rich accumulation of lighting knowledge.
