The Government announced last week that it's working toward legislating against the incandescent light bulbs that most of us have been using for years.
They'd be replaced by energy efficient flourescent bulbs or CFLs, which although more expensive to buy, use a quarter of the energy to run.
No-one disputes they are better for the environment and household budgets.
But opponents of the Government's move say it's another case of Labour over-regulating and taking away freedom of choice.
