What does EE lighting mean?
Energy Efficient Lighting is dictated by the light emission versus power consumption of various lamps. • In residential applications, a lamp is considered energy efficient when its luminous efficacy is greater than 40 lumens per circuit watt. • A circuit-watt is the power consumed in lighting circuits by lamps, their associated control gear and power correction equipment. • Luminous efficacy is a measure of how effective a lamp is in transforming electricity into light. It is measured in lumens per watt and often referred to as ‘lamp efficacy’. • This has become more relevant to the domestic user due to Part L of the Building Regulations which came into force in April 2006. It states: · Para 43: Reasonable provision would be to provide in the areas affected by the building work, fixed energy efficient light fittings that number not less than; a) one per 25m² of dwelling floor area (excluding garages) or part there of OR b) one per four fixed light fittings.
