The US is scrapping a ban on energy-inefficient light bulbs which was due to come in at the beginning of 2020.
The rule would have prohibited the sale of bulbs that do not reach a standard of efficiency, and could have seen an end to incandescent bulbs, reports BBC.
Many countries have phased out older bulbs because they waste energy.
But the US energy department said banning incandescent bulbs would be bad for consumers because of the higher cost of more efficient bulbs.
The Department of Energy said it had withdrawn the ban because it was a misinterpretation of the 2007 Energy Independence and Security Act.
