Low Energy Lighting
There are two main types of energy efficient light bulbs available in the UK. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs).
Both CFLs and LEDs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with an LED of the same brightness will save you about £3 to £6 per year.
LEDs are available to fit most 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.
