Unlike the majority of Italian production which is based in the north, iGuzzini is an established lighting manufacturer based centrally on the Adriatic coast. iGuzzini was founded by the six Guzzini brothers - Raimondo, Giovanni, Virgilio, Giuseppe, Adolfo and Giannunzio in the 1960s. The Guzzini company rebranded many times in the 20th century, going by, at various points - Harvey Creazioni, Harvey Guzzini, Guzzini, iGuzzini, and Illuminazione Guzzini. In the 1970s the company rebranded once more as iGuzzini—adding 'Illuminazione' in 1981. The company still exists today.
