Phase-out of incandescent light bulbs banned the sale of light bulbs over 40W on 1 January 2017. The UK government announced in 2007 that incandescent bulbs would be phased out by 2011. In 2008, the Irish government announced a phase-out of the sale of any light bulbs with a luminous efficiency of less than 16 lumens per watt. Shortly afterwards, all member states of the EU agreed to a progressive phase-out of incandescent light bulbs by 2012.
