Sales of halogen lightbulbs are to be banned in the UK from September, with fluorescent lights to follow, under government climate change plans.
The move will cut 1.26 million tonnes of carbon emissions a year and deliver consumers savings, officials say.
The UK began phasing out the sale of higher-energy halogen lightbulbs in 2018 under EU-wide rules.
Now retailers will no longer be able to sell most remaining halogen bulbs, such as kitchen spotlights.
Legislation for the plans is being brought forward this month by the government.
The plan will help continue the shift to low-energy LED lightbulbs, which account for about two-thirds of lights now sold in Britain.
It is expected to mean LEDs will account for 85% of all bulbs sold by 2030, officials said.
LED lights last five times longer than traditional halogen bulbs and produce the same amount of light, but use up to 80% less power.
I had no idea these lightbulbs, which we have as spotlights in our kitchen, are environmentally unfriendly.
