HC Deb 05 November 1973 vol 863 c45W
Mr. Skeet

asked the Secretary of State for Trade and Industry what research has been undertaken in the United Kingdom to produce a new fluorescent lamp which will produce more light for the same power consumption.

Mr. Anthony Grant

The British lighting industry has an extensive and continuing programme of research aimed at improving the efficiency of fluorescent lamps. Over the past 30 years the light output for a given power consumption has been increased threefold.
