Numero 3 is an intriguing name, it’s true! In fact it is not connected to the design of the object in itself, but to the fact that Numero 3 is the third lamp designed by Patrizia Bertolini, whose collaboration with Horm.it dates back to the early years of the company’s life. The steel base, which acts as a counterweight, is designed so that it can be placed under a table top to bring the beam of light to where it can be most useful. Base in brushed steel. Stem in solid black walnut. Fabric and PVC lampshade. Europlug CEE 7/16. We recommend the use of a compact fluorescent light (CFL) bulb 30 W MAX or a LED bulb. E27 socket. Do not use incandescent light bulbs.
