He quickly became aware that electricity would radically change our society, and he invested in the development and manufacturing of electrical devices, which still today is Lauritz Knudsen's primary business.
The period from the founding of the company until the late 1960s was characterised by an expansive product development. Lauritz Knudsen produced virtually everything that was electric - from irons, radios, speakers, stoves, electric clocks, power distribution boards and high voltage equipment. Today Lauritz Knudsen is focusing on sockets, outlets, data communication and intelligent house control for the residential area and commercial buildings. In 1968 Lauritz Knudsen merged with its largest competitor on the Danish market, the company NES, and changed its name to LK-NES. In 1995 Lauritz Knudsen merged with the Finnish group Ahlstrøm into a 50/50% Danish-Finnish-owned electricity group called Lexel A/S.
