Incandescent lamp and fluorescent lamp are two types of lightning electric materials. But they differ in several characteristics. On average, less than 10% of the power of an incandescent light is used to produce light and the rest of the heat. Therefore, it is a bad choice for energy conservation. Because the incandescent lamp produces lightning poor and low. It is cheaper to leave quickly and a good warm color and small size and its lifetime is relatively small.

Considering that a fluorescent lamp, compared to an incandescent lamp has high efficiency. About 20% of its energy input becomes lighter and 80% is converted into heat, including heat ballast lost. Fluorescent lamp will last longer. However, his life is affected by the number of times the lamp is switched on and off because switching is cover at least the cathode is not significantly affected by changes in voltage. But it is relatively large and expensive.
