Patterns formed by overlapping forest canopies informed the shape of Tala's new LED lightbulb, which it claims to be the largest in the world of its kind.
Tala launched the Voronoi III during this year's London Design Festival ? using it to illuminate an exhibition space in Shoreditch, where the company was presenting its designs alongside furniture pieces by SCP.

It's the latest bulb in the London-based company's Voronoi range, following on from the I and II models. While it is similarly made from mouth-blown glass and an LED fitting, Tala claims the newest version is the "world's largest sculptural bulb" in production.
The design of the bulb is intended to recall tessellating patterns ? or Voronoi ? seen in overlapping forest canopies, and was developed by Tala over a year-long period.
They began by 3D-printing a series of Voronoi structures in resin, before smoothing down sharp lines to give the impression of natural erosion. This gave the guide for the mouth-blown glass structure.
Inside the bulb, a custom-built LED filament curves around a central column, and ? again recalling nature ? is based pine cones and ferns found in forests.

"LED technology has enabled us to challenge the form of the light bulb and push the boundaries of mouth-blown glass for the first time," said Joe Armitage, Tala's design director.
Armitage, who is responsible for overseeing the design of all of Tala's products, also said the new bulb "encapsulates the fu...
