Experimentation with electric lighting began around 1802. Thomas Edison did not patent his practical implementation of the light bulb till 1878. It is amazing to think that just over 100 years ago no one had electric lights in their home.

"In the United States, federal law has scheduled the most common incandescent light bulbs to be phased out by 2014, to be replaced with more energy-efficient light bulbs. Traditional incandescent light bulbs were phased out in Australia in November 2009." Wikipedia.
