Speaking to the BBC, Lesley Urrutia, who has run Pilton Electrical in Cardiff for 25 years, said: "Elderly customers seem to be the most worried because they don't like the new energy saving light bulbs."
"They are panic buying because they have heard they won't be able to get traditional light bulbs anymore," she added.
However, people looking to switch energy supplier to cut their monthly energy bills may be interested to hear that modern bulbs can use up to 75 per cent less energy than their traditional counterparts. They also last between six and ten times longer.
Meanwhile, Australians have opposed legislation similar to the EU light bulb law, calling it "nonsensical".
