Zumtobel Group (also known as Zumtobel AG) is a company based in Dornbirn, Austria which comprises two sub-groups: Zumtobel Lighting Group, which includes the lighting brands "Zumtobel" and "Thorn"; and Tridonic, which manufactures lighting components. Thorn Lighting relocated its head office from Borehamwood, Herts to Spennymoor, County Durham at the end of 2010; the other divisions in the group are all headquartered in Dornbirn.
The division with the longest history in the group is Thorn Lighting, which was acquired from Thorn EMI in a leveraged management buy-out. Its integration in Zumtobel was completed in 2000. Thorn Lighting was founded in 1928 by Jules Thorn and Alfred Deutsch.
Zumtobel was founded in 1950 by Dr. Walter Zumtobel as "Elektrogeräte- und Kunstharzpreßwerk W. Zumtobel KG" in Dornbirn. The company produced ballasts for the newly introduced fluorescent light fittings.
Thorn Lighting had a lamp factory in Buckie (Scotland) which opened in 1956 and continued manufacturing incandescent 'light bulbs' until it closed in 1987. It also manufactured lamps at factories in Leicester (mostly auto and high and low pressure discharge), Merthyr Tydfil (incandescent) and Enfield (fluorescent) which were sold to GE Lighting in the early 1990's. It relocated its factory in Spennymoor, UK, to a new site in 2009 reducing its carbon footprint for manufacturing in the UK by 25%.
