On September 15th 2010 (at 3.32pm or thereabouts) London product design company Hulger pressed go on the Plumen 001. It was a breakthrough moment. Inside Hulger HQ faces beamed.
After four years of development, the team had finally realised a commercially viable, low-energy light bulb designed to be both sustainable and beautiful. The design conundrum that had evaded the makers of conventional chlorofluorocarbon (CFL) bulbs - with their blocky, awkward fluorescent tubes - seemed solved. It was that sumptuous moment of a project when you recognise the impact you are about to have on the world.
