For the first time as a finished product, the paper lamp w101 by Claesson Koivisto Rune, Stockholm, Sweden, was on display this week at the Northern Light Fair 2011 in Stockholm. The lamp, co-developed with Sweden-based Södra and Wästberg Lamps, has already been honored with multiple awards, including a Swedish Design Award and a Good Design Award.
Södra, Sweden, developed the DuraPulp grade used in the manufacture of the lamp. DuraPulp is made from selected pulp combined with PLA (polyactic acid), a renewable biopolymer produced from starch. The two components in combination provide special properties that can be reinforced through hot pressing. DuraPulp has high wet strength, high water resistance, and high dimension stability, as well as high tensile strength and bending stiffness. It is made from 100% renewable fibers and is fully biodegradable. It took seven years to research the Durapulp material and more time still was spent on the production process.
The entire structure of the high-tech LED task light is made of paper, constructed using sandwiched paper sheets of DuraPulp, For a paper, it is very strong and durable. But the folded geometry of the lamp also makes for rigidity, and is not just for sculptural effect, Södra explains.
The lamp structure is compostable and uses an absolute minimum of material. The custom-designed, state-of-the-art LED solution provides the most electricity-conserving, dimmable, quality light possible. The directed light itself puts the light where it is needed, without spill.
