Some of the lamps tested by Which?, including products from Ikea and TCP, would not meet the EU’s forthcoming minimum lifespan of 6,000 hours, the magazine said.
Which tested five samples each of 46 different bulbs. All of the lamps claimed a lifespan of at least 15,000 hours, but around 30 per cent didn’t even make it as far as 10,000 hours.
Ikea and TCP said the bulbs in question had now been withdrawn from sale.
A recent survey by the Energy Saving Trust found that around a third of households in the UK now buy LED light bulbs – roughly average for Europe. Swedish households leas LED adoption in Europe, with nearly half of homes buying LED lamps.
Tom Lock, certification manager of the Energy Saving Trust, said: ‘The most important thing is that consumers are given clear and accurate information about the quality of energy-saving light bulbs and that the cost and energy-saving benefits are fully realised.’
