The Green Party wants swift action into claims a magazine has made about the potential dangers of energy efficient light bulbs.
Investigate magazine published an article about the dangers of mercury levels in the light bulbs that Labour and the Greens want to be the public's only option.
They are looking to ban ordinary incandescent light bulbs if successful in this year's election.
The article claims the energy efficient bulbs have major safety implications for children and pregnant women.
Green Party co-leader Jeanette Fitzsimons wants an independent review.
