The incandescent light bulb is waning in energy efficiency, popularity, and cost effectiveness. Many countries and individual states are considering banning the sale of incandescent light bulbs in the near future. While one can debate whether a governmental authority should get involved in making a decision one restricting the use of incandescent light bulbs; one cannot debate that the compact florescent light bulb uses less energy. A great percentage of the electric power used with an incandescent light bulb is expended on heating up the light bulb compared with the amount of light generated from this type of bulb.
The compact florescent light bulb is longer lasting than an incandescent light bulb, uses less energy and is cooler to the touch. One can debate the quality of light offered by these two types of light bulbs; however from an energy efficiency standpoint the compact florescent bulb is the clear winner.
The next evolution in lighting will be the LED (Light Emitting Diode) bulb. Currently many people use LED Christmas tree lights. The LED technology uses even less energy than the incandescent and florescent light bulbs and last far longer than either of these types of lighting. Currently one of the major drawbacks to the LED lighting is the cost of the LED bulbs. As the production of LED light bulbs increases the costs should start to decrease.
