The HL post top is designed by Henning Larsen, who is the architect of the Copenhagen Opera House. HL post top consists of an untreated copper shade, a lower shade of clear/opal acryli. The lamp provides downward and diffuse light. In time the untreated copper shade gain a darker look and eventually it gains the classic verdigris colour. This beautiful, naturally occurring colour allows the lamp to grow more beautiful year after year. View the HL 590 Range
