Penta was designed by Jo Hammerborg in the mid-1960s and was only in production for a few years, which is why it is rare to see today. It has an ultra-strong metal frame in its original light grey colour, later repainted white, and is nicely done (white inside), measuring 40 cm in diameter and 20 cm in height. It has minor signs of wear, some chipping along the edge of the shades. Still a heavy lamp of good quality and a true work of design art that provides the best lighting. The link below presents the Penta lamp in the Fog&Mørup catalogue from 1965: https://www.danish-lights.com/jo-hammerborg-for-fog-m%c3%b8rup-penta/ Sold without bulb (has a standard E26/E27 socket) Packed securely and shipped with insurance.
