In the UK lighting consumes 58,000 TWh/y, equivalent to 18% of electricity production. Domestic lighting accounts for 26% of consumption (15,000TWh) and 15% of a typical household’s electricity bill. Smart lighting controls and energy efficient lights could cut consumption by up to 6% a year, for example by changing which bulbs we use and how we use them. Homes typically use a mixture of standard light fittings and down- or spotlights; energy efficient bulbs are available for both. Reduced energy consumption would also lower CO2 production and help meet government targets. 

Lighting is central to making a house a home. The right lighting allows you to perform tasks easily, and makes you feel safer and more comfortable. Lighting choices are guided by the function or use of the room, aesthetic requirements, degree of comfort required and cost. Factors such as energy consumption, lamps and ballast life, installation and maintenance costs must also be analysed. A more expensive system may be  justified by savings over its lifespan. Each room has specific general and lighting needs. Pendant or chandelier light is common in living rooms. When compared to pendant lights, chandelier lights with their multiple bulbs are generally more expensive and heavier. Chandeliers give a greater amount of light in a wide open space while pendants focus on a specific area.
