The difference between conventional and energy saving light bulbs.

Artificial lighting is one of the main discoveries of mankind. Now it is even difficult to imagine how our ancestors did without the use of bulbs in their homes or on the streets. In modern times, more advanced energy-saving light bulbs began to appear, which have a number of differences (both advantages and disadvantages) over the usual ones.

Definition

Probably, every person is at least a little familiar with the principle of operation of a conventional light bulb. Inside there is a tungsten filament, which is heated under the influence of an electric current, which gives good illumination. Typical service life is approximately one thousand hours.

Conventional incandescent lamp

The inside of the energy-saving lamp contains mercury and argon vapors. The inner surface has a phosphor - a special substance through which ultraviolet radiation passes. It is caused by the collision of electrons (under the action of voltage, they begin to move) with mercury atoms. The service life of an energy-saving light bulb is different: usually it is 8-10 thousand hours.

Comparison

Energy saving bulbs differ significantly from conventional bulbs. The main difference is energy consumption. It is not difficult to guess from the name that energy-saving light bulbs consume much less energy. With the same lighting of two types of bulbs, the energy-saving option will save up to 80 percent of energy.

The light from the energy-saving light bulb is soft and uniform. It is more pleasing to the eyes and does not make you squint too much, as, for example, the light from a conventional incandescent light bulb. Moreover, there is a possibility of choosing the desired color, since there are energy-saving bulbs that give white light, cold, warm and other colors.

The service life of an energy saving light bulb is much longer. An ordinary light bulb often fails, especially with constant use. The difference in service life is very significant: a fluorescent lamp works 5-15 times longer. It is especially important to use such lighting in those places where it is problematic to change a light bulb (for example, in a lamppost on the street).

When replacing an ordinary light bulb, everyone noticed that a strong heat emanated from it. Sometimes it is even difficult to touch it with your hands, since the incandescent light bulb is very hot. The energy-saving option does not have this problem due to its low heat dissipation. All of the above differences rather indicate a noticeable advantage of energy-saving light bulbs. But at the same time, they also have a very noticeable drawback - a high price.

Conclusions TheDifference.ru

  1. An energy-saving light bulb has a much longer service life, allows you to choose the color of lighting, and consumes less energy. But at the same time, the price for it is noticeably higher;
  2. Choose a light bulb based on how often you will need to use it, whether frequent replacement becomes difficult, or whether the heat from it affects the overall temperature in the room.
