First commercially available graphene light bulb

BBC : Graphene, the single-atom-thick arrangement of carbon atoms with a wide range of curious properties, was first isolated at the University of Manchester in the UK in 2004. Now, researchers from the university have contributed to the design of the first commercial consumer product to use graphene: a light bulb with a graphene-coated filament. The increased conductivity of the graphene reduces the bulb’s energy use by 10% and lengthens the bulb’s lifetime. The bulbs are expected to be available for sale later this year for under £15 ($22), which is less expensive than current LED bulbs.
