  • the eco friendly light bulbs have mercury in them. no thnx...

  • @ShoppingGurrrrl17 burning coal to power an incandescent releases more mercury than there is in a single cfl light bulb. And if accidentally breaking it and poisoning yourself with mercury worries you so much you can get an LED light bulb that last about 25 years and uses even less energy.
