Watts the difference [Power Energy Saving]

New legislation that is aimed at boosting the uptake of energy saving devices comes into effect this month and as the author explains it signals the end of the 100 Watt light bulb. The days of selecting 60W. 80W or 100W light bulbs off the supermarket shelf could soon be a thing of the past thanks to a new European directive that came into force this month. Consumers will be asked to learn the lumen, which regulators hope will make energy-saving products much easier to market and explain to users.
