LICHTZENTRALE, or "LZ" for short, and its core product range have always been a seal of quality for customers and suppliers. The "LICHT Zentrale" was founded in Nuremberg 40 years ago, on 28 February 1983. During our 40-year company history, however, we have not only developed immensely. Our product range has also become much more technically sophisticated and extensive over these four decades. In the early days, our customers still received our "Yellow Pages", the definitive reference work on the subject of lighting at the time. Over the years, the initial Leitz folder with interchangeable pages became a bound printed book in which our suppliers would very much like to be represented.
