http://www.differencebetween.net/technology/difference-between-led-and-incandescent/ WebA "normal light bulb" is also known as an incandescent light bulb. These bulbs have a very thin tungsten filament that is housed inside a glass sphere. They typically come in sizes like "60 watt," "75 watt," "100 watt" and so on. The basic idea behind these bulbs is simple. Electricity runs through the filament.
