Economical and reasonable owners of houses and apartments have increasingly begun to abandon traditional incandescent lamps and purchase, for example, halogen lamps that consume less electricity. Of course, such devices also have disadvantages. Their principle of operation can be considered in more detail.
How do halogen lamps work?
Energy-saving halogen lamps for the home - G9 and other models - in their principle of operation are similar to traditional incandescent models. An ordinary bulb has a rather large bulb made of frosted or transparent glass. Its capacity is filled with a gas mixture, usually nitrogen, argon, or both of these components at the same time. In the center is a tungsten filament, along which an electric current passes and heats it to 2500 ° C, which creates a glow. All “white” metals, including tungsten, glow white when incandescent, 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 with normal consumption, and this is from 12 hours a day, can work up to 1000 electric hours. Here the question may immediately arise: "Because of what is so much electricity wasted on her work?" This is because the energy consumption goes to the heat itself, which the lamp gives twice as much, and not to the light. Over time, due to the heat generated and large heating, the tungsten filament burns out, and sometimes even explodes. And this is precisely the main difference between an incandescent lamp and a halogen.
Metal halide lighting devices are also created using tungsten filaments, but they are placed in a much smaller quartz bulb. 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 degrees of temperature.
The gas in the incandescent lamp and the halogen is also different. For the second option, experts have developed a substance with tungsten evaporation, which forms gaseous halogen vapor. When combined with tungsten vapors that do not settle on surfaces and disappear without a trace, the service life of the threads is significantly extended. Also, thanks to such a versatile gas mixture, the temperature of the threads decreases. When halogen is used, the thread likewise transfers its heat to space, but already 1.5 times less than when using nitrogen or argon. This operation of the devices can significantly reduce the cost of electricity.
The advantages of halogen lamps
Halogen-based lighting products have a number of distinctive characteristics. The positive qualities include the following:
- Excellent for use when increased eye attention is required. The emitted bright light reduces eyestrain, does not overstress the crystalline.
- Great for lighting systems related to advertising tasks, for example, to attract potential buyers or customers. For window dressing, white light is the best option. Using halogen spotlights, you can create spot focus. It was noted by many that during operation of the halogen, the colors of the surfaces become more intense and saturated, the colors more vibrant.
- Built-in halogen floodlights are considered the most suitable for backyard lighting. Like their LED counterparts, they withstand temperature extremes and are resistant to external factors and precipitation. The main thing in this case is their complete sealing. Searchlights and halogen lamps for the home, the photos of which can be carefully examined before buying, somewhere around 20% are more economical than similar incandescent ones. Their distinguishing feature is a very bright light that illuminates all corners of open space.
Halogen lamp disadvantages
There are also disadvantages of halogen lamps for the home. The disadvantages of the devices are as follows:
- Bright white lighting does not appeal to all people. It hits the eyes hard and is not always appropriate. You can not meet halogen chandeliers for the ceiling of a bedroom or a nursery. If they are installed in these rooms, then only at an angle and under the guidance of experienced electrical engineers, according to the strategy developed by them.
- Although the outer shell of the lamps is very durable, it can still be damaged, and in this case, gas dangerous to humans will come out. Its presence in a small amount is not particularly harmful, but if the halogen is not one, then this can provoke dizziness and migraines.
- Halogen lamps for the home, which have the same disadvantages as any other device, are not recommended for installation in the bathroom. Here they will be under the constant influence of evaporating moisture and may explode after a short period of operation.
- Shards, plinths, and cartridges need special disposal. Do not throw halogen lamps for the home into the bucket. The disadvantages are also evident. The damaged device must be sent either to a universal container for the disposal of chemical waste, if any, or transferred to a company specializing in such services.
Consumer opinion
Before you buy halogen lamps for the home, reviews about them must be studied first. At first, some consumers may be frightened off by the cost of such devices, since their price is considerably higher than that of standard incandescent lamps. Nevertheless, halogen lamps for the home are very beneficial. The disadvantages associated with high initial costs for the purchase, after a while justify themselves handsomely. From the reviews you can see that people are very satisfied with the durability of the devices, saving energy consumption.
Mounting Feature
The installation of halogens differs from the installation of traditional incandescent lamps in that they have a quartz coating, which is not recommended to be touched with your hands, so as not to disturb its structure. If this happens, the device may not work or explode. It is important to observe a clear sequence when installing such a plan for lighting.
