How Do Twisty Light Bulbs Work?
By Sharon Fabian 		  
1     Compact fluorescent lights (CFLs) are an efficient new way to produce light. They come in the familiar twisty light bulb shape and in other forms as well.
 
2     CFLs are much more efficient than traditional incandescent light bulbs. They produce more light using the same amount of electricity.
 
3     Traditional incandescent light bulbs use a filament to produce light. The filament is heated until it is white-hot, so these light bulbs give off a lot of unwanted heat. CFLs do not use a filament and do not produce as much heat.
 
4     There are two main parts to a compact fluorescent light bulb, a gas-filled tube and a ballast.
