Soon, light bulbs made with super-strong carbon to cut energy use by 10pc, last longer

Light bulbs made with super-strong carbon or graphene will be available in the market later in 2015, which will cut energy use by 10 percent and last longer owing to its conductivity.

The dimmable bulb contains a filament-shaped LED coated in graphene. It was designed at Manchester University, where the material was discovered, the BBC reported.

The light bulb was developed by a Canadian-financed company called Graphene Lighting - one of whose directors is Prof Colin Bailey, deputy vice-chancellor at the University of Manchester.

Based on traditional light bulb design, the use of graphene allows it to conduct electricity and heat more effectively.

It has been expected to be priced lower than some LED bulbs, which can cost about 15 pounds each.
