We test light bulbs on how long they will last turning them on and off 30,000 times.

Low-energy light bulbs may be more expensive than traditional bulbs but in the long run they work out cheaper, Which? reveals today

That’s because traditional bulbs use more electricity and have to be replaced more often.

We found that switching one 100-watt incandescent bulb for a Best Buy low-energy bulb could save up to £30 over five years.

And according to our calculations, if each UK household used just one energy-efficient light bulb, enough electricity could be saved to allow a power station to be shut down.

Rigorous testing

Which? immediately started testing the newer-style energy saving light bulbs when they became available in July 2006.

Our trials included a rigorous lifetime test, where bulbs were turned on for 8,000 hours, the equivalent of at least eight years of use.

Which? Online Editor Malcolm Coles said: ‘We want to turn people on to energy-saving light bulbs which give the double whammy of being good for the planet and good for the pocket.

‘Traditional light bulbs’ days are numbered – they may be dirt cheap, but they're a false economy.’
