Energy efficient lighting helps lower electricity bills and carbon dioxide emissions.
If you replace all the bulbs in your home with LED lights, you could reduce your carbon dioxide emissions by up to 40kg a year. This is equivalent to the carbon dioxide emitted by driving your car around 145 miles.
Lighting makes up 11% of the average UK household electricity consumption, so making the switch could help you save money too.
