A low energy lightbulb

Energy-saving light bulbs come in a number of shapes with a variety of different fittings

More than nine in 10 Which? members have tried energy-saving light bulbs, but few use them in all lights due to reservations about them.

Major shops stopped selling 100-watt traditional incandescent bulbs in January and other sizes will follow in the next few years as part of an agreement between shops and the UK government. EU law means that all incandescent bulbs must be phased out by 2012.

When we questioned 1,981 members of our online panel, we found that 82% had a concern about low energy bulbs.

We also found that nearly one in five are already building up a stock of traditional light bulbs.

Concerns about bulbs

Members’ main concerns over energy-saving light bulbs include fear of cost, being able to find the right-shaped bulbs, whether they're compatible with dimmer switches and whether they produce light quickly enough. 

About 14% of members in our poll had installed energy-saving bulbs everywhere in their home.

In January 2010, 60-watt standard bulbs are set to be phased out.

The most popular size (40-watt) will follow in January 2011, together with 60-watt golf- and candle-shaped bulbs .

Maximum light, minimum cost
