Structure 2004.pdf Information on the phasing out of low efficiency light bulbs On 18 March 2009, the European Commission adopted two regulations under the Eco-design Directive that confirmed a ban on the sale of all incandescent and low-efficiency halogen light bulbs by 2012. Through these regulations, the EU aims to improve the energy efficiency of household lamps and office, street and industrial lighting products. The first regulation on household lighting made it illegal to sell light bulbs of less than C-class efficiency under the EU's energy labelling system. After 2009 this requirement applied to bulbs that have a light output equivalent to an incandescent bulb of 100 watts or more. It is being extended to lower wattage bulbs in stages until all are covered by September 2012. A second regulation on office, street and industrial lighting will see the least efficient fluorescent lamps, high-intensity discharge lamps and related ballasts and luminaries phased out in four stages from 2010 to 2017. The commission says the measures will reduce energy consumption from such equipment by up to 15% by 2020. The English Building Regulations require 75% of energy efficient lighting in a new or refurbished domestic property. Energy efficient lighting is defined as having a luminous efficacy greater than 40 lumens per circuit watt. Circuit-watts means the power consumed in lighting circuits by lamps and their associated control gear. Fluorescent and compact fluorescent lighting fittings would meet this standard. Tungsten lamps or tungsten halogen lamps would not. Watts have traditionally used to rate light bulbs but as this is a measure of power, which does not taking into effect what we actually see. So the use of Lumens is being introduced which is a measure of the power of light perceived by the human eye. By way of comparison:
