While Europe's leaders were last week urging householders to fit energy-efficient light bulbs, several governments were busy attempting to block moves to cut their price.
A European summit agreed to toughen regulations against old-fashioned incandescent bulbs by 2009 as part of a bid to cut greenhouse gas emissions. But earlier in the week officials from trade ministries rebuffed attempts by the European Commission to end five-year-old surcharges on imports of energy-efficient bulbs from China.
