What if light bulb did not exist?
There is some air pollution and a danger of fire or asphyxiation or explosion with some of these technologies. If there were no electric light bulbs, we would still want to see after it got dark, so we would use other lighting technologies. Excellent bright lighting is provided by combustion with a mantle.
What will happen to the light of the bulb?
When a light bulb connects to an electrical power supply, an electrical current flows from one metal contact to the other. As the current travels through the wires and the filament, the filament heats up to the point where it begins to emit photons, which are small packets of visible light.
What is the point of a light bulb?
A light-bulb produces light from electricity. In addition to lighting a dark space, they can be used to show an electronic device is on, to direct traffic, for heat, and for many other purposes. Billions are in use, some even in outer space. Early people used candles and oil lamps for light.

How do you change the light bulb on a globe?
Simply pull the globe off. Carefully tug a bit on the metal frame and see if it will pull down. The whole frame and dome will come down enough to swing out of the way so you can change the bulb. For the one with two big metal clips INSIDE the glass bowl, just pull to one side until the first side unclips (putting it back on is more nerve wracking!)
