Italian designer Luca Nichetto has created a lamp for Scandinavian design brand Hem, which comprises colorful shades that stack in customizable combinations. The spun-steel shades of Nichetto’s Alphabeta lamp are used in pairs to direct light up and down from the source. Each of the shades can be selected by the customer online in any combination of shapes and colors – there are more than 10 billion possible combinations, all in-stock, and shipped free to Hem customers. The different shapes include cones, bowls and tubes, all available in a variety of lengths and widths. When displayed in groups, they look like letters in the alphabet.
