Eco-friendly light bulbs causing more harm than good

There are new questions about the safety of eco-friendly light bulbs.

German government scientists warned that pregnant women and children could be at risk if the energy-saving light bulbs are broken, releasing potentially harmful amounts of mercury into the air.

Critics also said bulbs can trigger epileptic fits, migraines and rashes.

Incandescent light bulbs will be phased out in Canada in 2012.
