Ceiling lamp designed by franco albini, franca helg and antonio piva and manufactured by sirrah in 1969. the model is a part of the am/as series that includes table lamps, wall lamps, floor lamps and suspensions. The lamps are available with easily interchangeable white glass diffusers or chromed metal screens. This is model as41z. the ceiling lamp has a double-linked arm which is not only aesthetically pleasing, but also offers full flexibility. The length of the electrical cord (maximum 105 cm / 41 inch) can be adjusted with the metal disc (see picture). the relatively large semi-sphere is made of chromed metal. In two places (at the ceiling and above the half sphere) screw threads have been applied with which the different parts can be put together. the am/as series is described in the repertorio del design italiano 1950-2000 by giuliana gramigna on page 166 (1969). I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
