Apparently the lampshade is supposed to be in the shape of the singer's signature weave-hive hairdo. The 'Amy' lamp is available as a floor lamp ($1500), and as a table light ($740). According to Splash:

The European firm behind the product, Delightfull, says of the lamp: 'Inspired by what makes her unique, Amy is a tribute to the great British singer and songwriter. It's an elegant piece, with personality, outlined by detail, surrounded by the black of her hair and of her golden voice.'
