It is expected to be priced lower than some LED bulbs, which can cost about £15 each.
Based on traditional light bulb design, the use of graphene allows it to conduct electricity and heat more effectively.
Prof Bailey told the BBC: "The graphene light bulb will use less energy. We expect it to last longer. The manufacturing costs are lower and it uses more and more sustainable components.
Now we have an even better product, even cheaper!

The 'perfect' light source would produce only light, wasting no or very little energy as heat. The old tungsten filament type lamps are terrible energy munchers as they rely on superheating the filament to create light so a comparison of the latest led tech with the graphene lamps will be interesting and the key to which will win the race ultimately.
