Halogen lamps for home: deficiencies, reviews, photos

Economical and reasonable owners of houses and apartments increasingly began to abandon the traditional incandescent lamps and acquire, for example, halogen lamps that use less energy. Of course, such devices also have drawbacks. Their principle of work can be considered in more detail.

How do halogen lamps work?

Energy-saving halogen lamps for the home - G9 and other models - are similar in their operation to traditional incandescent models. A regular bulb has a rather large bulb of frosted or clear glass. Its capacity is filled with a gas mixture, usually nitrogen, argon or both. In the center there is a tungsten filament, through which an electric current flows and heats it to 2500 ° C, which creates a glow. All the "white" metals, including tungsten, glow with white when lit, but thanks to the bulb the lighting can be made cold or warm.

The difference between a halogen and an incandescent lamp

A standard incandescent lamp at normal consumption, and this from 12 hours a day, can work up to 1000 hours. Here at once the question may arise: "Because of what is spent so much electricity on her work?" This is because the power consumption goes to the heat itself, which the luminaire gives twice as much, and not as light. Over time, because of the resulting heat and large heat, the tungsten filament burns out, and sometimes even explodes. And this is precisely the main difference between the incandescent lamp and halogen lamps.

Metal halide lighting devices are also created using tungsten filaments, but they are placed in a quartz flask of much smaller size. A simple glass, located at such a short distance from the filaments, will begin to melt, and quartz, on the contrary, increases its resistance to high-temperature temperatures.

The gas in the incandescent lamp and halogen is also different. For the second option, the specialists developed a substance with tungsten evaporation, which forms a gaseous halogen vapor. When combined with tungsten vapors that do not settle on the surfaces and disappear without a trace, the life of the yarns is significantly extended. Also, due to such a universal gas mixture, the temperature of the filaments is reduced. When halogen is used, the thread likewise gives its heat to the space, but it is 1.5 times smaller than when using nitrogen or argon. Such a functioning of the devices allows to significantly reduce the consumption of electricity.

Advantages of halogen lamps

Lighting devices based on halogen have a number of their distinctive characteristics. The positive qualities include the following:

- Excellent for use when eye care is required. Radiated bright light reduces visual tension, does not overload the crystalline.

- Excellent for lighting systems associated with advertising tasks, for example, to attract potential buyers or customers. For decoration of shop windows, white light is the best option. With the help of halogen spotlights, you can create spot focusing. Many noted that during the work of halogen the colors of surfaces become more intense and saturated, the colors are more lively.

- Halogen floodlights of built-in type are considered the most suitable for yard illuminations. Like their LED counterparts, they are excellent for withstanding temperature changes, are resistant to external factors, precipitation. The main thing in this case is their complete sealing. Spotlights and halogen lamps for the home, photos of which before purchase can be preliminarily studied, whereby by 20% are more economical than similar incandescences. Their distinguishing feature is a very bright light that illuminates all the corners of the open space.

Disadvantages of halogen lamps

Have and minuses halogen lamps for the house. Disadvantages of the devices are as follows:

- Bright white light does not suit all people. It hits hard in the eyes and is not always appropriate. To meet halogen chandeliers for the bedroom or children's bedroom can not often. If they are installed in these premises, then only at an angle and under the guidance of experienced electrical engineers, according to the strategy they developed.

- Although the outer shell of the lamps is very strong, it can still be damaged, and in this case a gas that is dangerous to humans will come out. Its presence in a small amount is not particularly harmful, but if the halogen is not one, it can provoke vertigo and migraines.

- Halogen lamps for the house, the disadvantages of which are the same as that of any other device, do not recommend installing in the bathroom. Here they will be under constant exposure to evaporating moisture and may explode in a short period of operation.

- Shards, socles and cartridges need special disposal. Do not throw in the bucket halogen lamps for the house. Disadvantages here are also evident. A damaged device must be sent either to a universal chemical waste disposal container, if available, or to a company specializing in similar services.

Consumer opinion

Before you buy a halogen lamp for the house, reviews about them should be studied first. Some consumers at first can be deterred by the cost of such devices, since the price for them is considerably higher than that of standard incandescent lamps. Nevertheless, halogen lamps for home are very beneficial. The shortcomings associated with high initial costs of buying, after a time justify themselves a hundredfold. From the reviews you can see that people are very satisfied with the durability of devices, saving power consumption.

Feature of installation

The installation of halogens differs from the installation of traditional incandescent lamps in that they have a quartz deposition, which is not recommended to touch hands to disturb its structure. If this happens, the device may not work or will explode. It is important to follow a clear sequence when installing such a plan for lighting equipment.
