Title: "Royal Ediswan"
Post by: Tim on September 02, 2003, 07:20:00 am

Can anyone tell me when the name "Royal Ediswan" first appeared regarding light bulbs, and when the name was dropped?  I want to say 1920s but I'm not sure if this is correct.

Thanks in advance!

Hi Tim,

Brief history here for you of names marked on lamps made by this company:

1880    Swan
1882    Swan United
1883    The Edison Swan (or just Ediswan)
1905    Royal "Ediswan"
1928    Royal Ediswan (under AEI ownership)
1958    Royal Ediswan (under BLI ownership_
1967    Ediswan (under Thorn ownership)
1972    End of the Ediswan name.  Over the years the Thorn Lighting Group had expanded to include the lampmaking activities of BTH, AEI, Ediswan, Mazda, Omega, Atlas, Ensign, Ecko, British Siemens, British Westinghouse, Metropolitan-Vickers and these names were gradually all dropped in the run-up to 1972 when the amalgamations were completed and Thorn Lighting Limited was formed.  However the Mazda name was re-introduced for domestic lamp sales in 1987.  In 1991 GE took over the Thorn Lamps division and therefter the Thorn name disappeared but GE-Mazda continues as the brand name for domestic lamp sales.

Hope this info is of help!

Best regards,

James.
