The unusual murano glass spiral lamp, model 048 by leucos, was made in italy in the seventies. It can be used as a ceiling, table or wall lamp. founded in 1962 in scorzè, on the outskirts of venice, and subsequently moved to the salzano district, leucos soon became a leader in decorative glass lighting thanks to its ability to explore different contemporary creative and production possibilities. the electrical system is fully functional and includes 3 e14 lamp holders with adapters, we can make it e12 for the usa. as shown in the photo, there is a small chip on the glass but it is not visible because it is hidden once assembled.

I take full responsibility for any authenticity issues arising from misattribution, european plug (up to 250v).the wiring of this item may be original and might need replacement, if not specified otherwise.
