Cologne 2015: the first collaboration between German designer Sebastian Herkner and Danish furniture manufacturer Gubi has resulted in a minimal pendant lamp.

Each design in Sebastian Herkner's collection features a hand-blown glass bulb and a spun aluminium "collar", added to reflect light onto the ceiling and give the product a distinctive appearance.

According to the designer, the form of the Collar Lamp was driven by the combination of the two materials used.

"I have an approach to materials and the production process, which is often my starting point and inspiration," Herkner told Dezeen. "In this case it was the combination of metal and glass in a lamp."

The Collar Lamp comes in two sizes and is available in five different colours: black, grey, taupe, terracotta and sand.

"As Collar Lamp is designed in two sizes and five colours, it is easy to put your personal touch to it by mixing sizes and colours," said Herkner.

"But of course it is also perfectly suited as a pendant lamp over the dining table. It has an international spirit with a distinct Nordic touch."

The collaboration between the Danish manufacturer and the German designer began two years ago.

"Jacob Gubi and I had the first conversation at Maison&Objet in Paris in 2013," Herkner told Dezeen.

"We talked about quality, tradition, genuine materials, and value. All these attributes are important to Gubi and to me as a designer," he said.

The Collar Light was launched at imm Cologne last month, where Claesson Koivisto Rune presented a stripy wooden furniture collection and Neri&Hu installed its vision of the home of the future.
