Designed in 1919 by Johan Petter Johanesson, the Triplex lamp is an industrial classic favored by collectors in Sweden. One of those aficionadoes, Robert Kullenberg, an engineer, has formed a design company called Mackapar, dedicated to bringing the Triplex back into production. Kullenberg expects his first batch of 100 Triplex lights to be available in spring 2011; follow the progress at Mackapar.
