I just realised the silver / white pendant lamps I have from an exhibiton at Gammel Strand 1992 (Louis Poulsen´s showroom in Copenhagen) supposed to have coloured bulbs in them. The only picture I have from the exhibition is taken in daylight so you don´t see the colours very well. Now I tried with blue, green, red and yellow bulbs as in the exhibition picture and the lamps turned out very cool. Only a few pendant lamps was made just for this exhibition.
