Lighting accounts for 18 per cent of a typical household’s electricity bill. You can cut your lighting bill and energy use by changing which bulbs you use and how you use them. Houses typically use a mixture of standard light fittings and down lighters or spotlight fittings. Energy efficient bulbs are available for both types of fittings.
Which light bulbs are energy efficient?
There are two main types of energy efficient light bulbs available in the UK. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).
CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a CFL of the same brightness will save you about £5 per year, or £70 over the lifetime of the bulb.
LEDs are available to fit both types of fittings and are particularly good for replacing spotlights and dimmable lights, they are more efficient than CFLs and will save you more money in the long term. By replacing all halogen downlighters in your home with LED alternatives, you could save about £35 a year on your electricity bills.
