London Design Festival 2015: to celebrate British design brand Another Country's five-year anniversary, Studio Dessuant Bone has designed a lamp to reflect the company's origins in the seaside county of Dorset (+ slideshow).

The limited-edition lamp features a spherical bulb that is suspended from a short brass arm at the top of a cylindrical stone base.

Titled Jurassic Light 117, the lamp is designed to look like the iconic geological landmark Durdle Door on the Dorset coastline.

This naturally formed limestone arch on the Jurassic Coast influenced the form and shape of the lamp.

"The cylindrical negative space created by this arch has been interpreted to create the simple shape that forms the light," said Studio Dessuant Bone co-founder Philip Bone.

"When designing the piece we had a very strong image in our minds of the sun shining through the Durdle Door against the soft Portland Stone," said the studio's other co-founder, Marie Dessuant, who has previously designed candle holders with handy inner compartments for the brand.

"We translated this idea in a more geometrical shape with the brushed brass arm and the frosted light source acting as the sun against the simple cylinder," she told Dezeen.

The base of the lamp is made from a limestone sourced from the Isle of Portland, also in Dorset.

"We chose the Durdle Door as inspiration because we were very excited about the idea of using Portland Stone," Bone added. "It has an amazing colouration and a unique texture with its fossil print."

A brass dimmer switch is used to control the levels of light emitted from the bulb, allowing the user to select their preferred brightness.

"It's also a reminder of the different light throughout the day that occurs in Dorset at the Durdle Door," said Bone.

Another Country's first collection, launched in 2010, was developed and produced in the southern English county. For its fifth anniversary, the brand asked a variety of designers to create furniture and homeware products influenced by the area's countryside and history.

Jurassic Light 117 was shown during London Design Festival 2015 as part of Dorset Series, which took place from 19 to 26 September 2015 at the Another Country store in Marylebone.

More lighting projects from the brand include The First Light collection from Canadian designer Dana Cannam and a collaboration with New York studio Workstead to create a lighting range formed from reconfigurable metal rods.
