How the Thomas Edison’s lightbulb evolved:
The lightbulb was invented in 1879 in Thomas Edison’s laboratory. He made the first high resistance, incandescent lightbulb. Over the year’s lightbulbs became more and more accessible and eventually it would be in every household. Later on they started making lightbulbs out of more environmentally safe products these lights are called halogen incandescent lightbulbs and they are much more environmentally friendly than common old lightbulbs. Now we have all sorts of lights such as LEDs, CFL bulbs, fluorescents etc.
