What is the Graphene light bulb?

The graphene lightbulb has been the subject of a huge amount of speculation over the last few days.

What is it?

The truth is, nobody outside University of Manchester spin-out Graphene Lighting knows, so ignore anything you have heard or read.

“As a scientist, I would love to say…
