Frequency is a linear LED lamp made of blown glass designed by Marcantonio Raimondi Malerba. Frequency exists in two versions, both hanging. The first can be installed horizontally, over a dining table, above a reception desk or a desk in an office. The second is installed vertically, and works like a floor lamp, but without any obstacle on the ground, since it does not have a base. Frequency, like all Cangini and Tucci lamps, is entirely handmade in Italy.
