Light bulbs are the main souce of light in Ember, Because the city is underground there had to be a source of light for the city. There were many storerooms underground that held many cases of lightbulbs. Lightbulbs were powered by the generator under the city.

Lina Mayfleet often wondered which would happen first: the generator breaking down forever or the city running out of lightbulbs.
