Between 1995 and 1998 we worked on the re-lighting of the whole of the Gulbenkian Museum. The galleries vary widely but often have a range of object types with varying light sensitivity from carpets, manuscripts and textiles, to ceramics and glassware. We used subtly changing light gradient from low level over carpets and textiles to slightly higher levels over those neighbouring objects less susceptible to light. The whole effect gives a pleasing appearance for the visitors, with all objects lit in a way that increases their appreciation by the viewer whilst staying within conservation limits.
We introduced new fibre-optic lighting into certain cases to deliberately bring out the best features of individual objects and changed the balance of lighting in other cases to increase the emphasis on the objects rather than the case background.
