Electric lighting typologies
Many artworks suffered from excessive exposure in the early daylit art galleries, and this brought about a reaction against daylight that was particularly pronounced in the period of reconstruction that followed the Second World War. Electric lighting was seen to be the safe alternative, and new galleries were often designed for little or no daylight, while many existing galleries had their fenestration blanked off. A few electric lighting systems were developed specifically for museum and art gallery use, but for many years they made little headway against the display lighting systems that were widely marketed for commercial display applications. Many examples of unsatisfactory lighting ensued, with lighting that failed to provide adequately for either visual or conservation requirements.
