The company continues to expand in the fifties thanks to a number of
innovative ideas. Following various wooden luminaires for fluorescent
lamps the first multiple-stem clusters made of brass and aluminium are
produced in 1951.
Linear fluorescent diffusers made of glass (1954) and louvred luminaires
(1955) complete the range. 1955 saw the development of punched metal louvres
for the production of diffusers.
