The board of Strand Electric decided on 5th January 1954 to make no further sales of the Electronic and associated dimmers, due to the technical problems and hidden costs caused by the need for isolation transformers to reduce electrical losses. (from research by David Bertenshaw)
There were just over 30 installations in total, in 6 years of existence.
