73.1 Semi-Rigid is a ceiling lamp from Bocci designed by Omer Arbel in 2015. The lamp has a pendant with an adjustable height up to 300 cm. The irregular shape is the result of blowing liquid glass into a pleated and highly heat-resistant material which, after solidifying, gives a textual appearance associated with fabric. The lightbulb measures approximately 26-30.5 cm in width and is made by hand, meaning that each is completely unique in proportion, size, and shape. 73.1 Semi-Rigid is available in gray or clear glass and is horizontal, meaning that the pendant is hung from the ceiling fixture with a thin braided metal cable. For example, it can be placed around a corner or at different distances to create the illusion of suspending gravity. The lamp comes with a round ceiling bracket in brushed nickel.
