Under Turnbull's plan, light bulbs that do not comply with energy efficiency targets would be gradually banned from sale.
"It's a little thing, but it's a massive change," Turnbull told Australia's Nine Network television.

Exemptions may apply for special needs such as medical lighting and oven lights.
Last month a politician in the US state of California said he was preparing to introduce a bill banning incandescent bulbs from sale.
