The Buzz Word is LED, LED, LED
Most of us have changed from traditional light bulbs to energy saving ones. But there is now a range of lower energy bulbs that you can install to save you more money.
Even halogen spot lights can be replaced - the new LED (light emitting diode) bulbs are bright enough to do the job.
They are priced between £4 and £20 and come in a variety of shapes, sizes and fittings. If your supermarket doesn't stock them, most DIY stores do.
The Energy Saving Trust recommended logo can give an indication of light quality and durability.
For the average household, changing all bulbs would cost around £125. The low energy versions would last longer and save around £60 a year.
