The iconic "Spirale" table lamp was designed by Angelo Mangiarotti for the Milanese manufacturer Candle. It consists of a chrome-plated steel spring with a concealed switch in the base. To turn the light on and off, simply press the spiral downwards. The lamp is 25 cm high without the light source; including the E27 globe bulb, as shown here, it measures 37 cm.
