For a century, incandescent light bulbs were the main light source in British homes - until they were banned by the EU.
But incandescent bulbs - which were phased out since 2009 under European regulations - could make a comeback.

The bulbs - which rely on a thin wire filament - were branded environmentally unfriendly as 95% of the energy they used was lost as heat.
But the new MIT lights could have 40% efficiency as opposed to 5% - and just 14% for LED or fluorescent bulbs.
