Any motorist, even with a little experiencedriving, perfectly aware of the importance of good lighting on the road. Especially with poor visibility, where you can take heavy rain, dense fog and other natural phenomena. However, many drivers are interested in the question of which H7 low beam lamps are the best. Most car manufacturers complete their products with this type of headlamp lamps. But not every vehicle owner knows what they are.
Description
Какое-то время назад среди многих автолюбителей H4 lamps, which have two filament yarns, were also very popular, which makes it possible to switch on the far or the near light. Now they are replaced by a good alternative - H7. She already has one filament, and the lamp is installed in a four-head head optics with a divided system of reflectors for far and near illumination. However, such elements are placed mainly in dipped-beam headlamps. And for optics of distant illumination, H1 lamps are still used, which are already outdated, but have a low cost.
The characteristic difference of these products ispresence of flange. At the same time, the distance between it and the helix is fixed and constant. Thanks to this, the filament is in focus all the time. What are the best H7 low beam lamps for the Kalina or any other domestic or foreign cars? Let's figure it out.
Low light sources
Modern automotive technologyindustries allow manufacturers to produce a variety of products for head optics. In addition, each company relies on its own development and experience. For this reason, all lamps with a H7 base have different parameters regarding power and spectrum of illumination, which can range from cold to warm tones.
As for power, according to the standard for H7 lampsit is 55 watts. However, on the market there are models with higher values. Only to acquire them is recommended to owners of off-road vehicles when driving out of town. Usually in megacities the roads are well lit. The use of strong lamps on the car, which is used mainly for movement on city streets, can lead to overloads. And as a result - the onboard electrician will fail.
Many drivers, especially novices, every now and thendon't stop worrying about which H7 low beam lamps are the best. Today there are plenty to choose from, as the modern market is filled with different types of headlamps:
- halogen;
- xenon;
- LED.
При этом лампы одних брендов отличаются the increased luminous flux, other manufacturers assure consumers that their lamps serve three times longer than their competitors, and still others can only decorate head optics with their appearance. It is worth considering each of the types in more detail.
Standard
Usually for making a bulbhigh-strength glass or quartz material is used. In its internal part there is a filament and a gas with the inclusion of halogen additives. Nowadays such lamps are deservedly popular due to their wide distribution. The use of such products does not require any additional equipment. Lighting they create the right and, most importantly, quality.
There are also a number of other advantages that allow us to immediately answer the question of which H7 low beam lamps are the best on a Priora or a different car:
- compact size;
- long service life;
- for the light of the quartz shell have high strength and heat resistance;
- high luminous efficiency;
- extensive scope.
However, there is a significant drawbackwhich consists in strong heating of the lamps during operation and poor tolerance of voltage drops. When replacing the lamps, it is strictly forbidden to touch the glass bulb with your hands. Fortunately, there are not many drawbacks, and for this reason today more than a million cars drive with such low-beam lamps.
Xenon Solutions
In appearance, you can see almostthe complete similarity of discharge lamps with halogen analogues. However, both light sources use different technology. In this case, a characteristic feature is the complete absence of an incandescent filament, since a different principle is used.
What are the best H7 dipped bulbs onDuster? Perhaps it’s just that, because they have a special principle of work. The luminous flux is created due to the inert gas emission of xenon, from where the name of the lamps themselves came from. In a glass flask, it is under pressure. Here is a small metal plate that heats the inert medium. Due to the absence of an incandescent filament, such lamps are not afraid of vibration, which is confirmed by many tests. Compared to the classic halogen counterpart, the xenon glow is three times brighter. This becomes especially true when driving in the evening and at high speed.
Among other advantages, it is worth highlighting the following:
- low power consumption - about 35 watts;
- the estimated service life is 2800-4000 hours;
- lighting brightness - 3000 lumens;
- the luminous flux is as close as possible to sunlight.
Due to the characteristics of xenon lighting issueabout which low-beam lamps H7 are the best for Kalina, should not arise at all. The driver clearly sees almost all objects on the road and roadside (including road signs) at a great distance. When traveling by car in dense fog or heavy rainfall, the so-called “light wall” is not created. Rays are able to break through such an obstacle, thanks to which it is the road that is visible, and not a drop of rain or fog.
Why, then, having suchirrefutable advantages, xenon lamps still have not completely replaced halogen analogues from the market. It's all about the flaws. For such lamps to work, they need an additional ignition unit. To start them, a voltage of 25 kV is required, and during operation they consume less - 80 V. Another no less serious minus is the high price. In addition, it is recommended to install such lamps only on those car models that are equipped with a headlight range control, otherwise dazzling oncoming drivers cannot be avoided.
LED alternative
In deciding which lamps are dippedH7 lights are the best for Nexia, Ford or any other car, many experts unanimously agree that the future is with the LED. And this applies not only to the automotive industry, but also to most other industries where there is a need for high-quality lighting.
Such lamps are the most economical amongall other analogues. Compared with incandescent elements, energy consumption is lower than every 10 times. And as regards the service life, it is believed that LEDs can work up to 100 thousand hours. They also tolerate vibration and shock, and the luminous flux meets many requirements. Due to the absence of mercury, such lamps are completely harmless, so they can be safely disposed of. Only here there is one important detail - their use requires special optics. Due to their peculiarities, LEDs cannot illuminate pointwise, which imposes certain difficulties, since conventional optics do not allow you to adjust the luminous flux.
What are the best H7 low beam lamps inrain? The choice fell on the LEDs, but it is worth knowing about a number of shortcomings. The most important of them is the very high cost, due to which this market segment is not so common. Another equally important point is that the declared period completely refutes the practice. Instead of 11 years, the manufacturer himself guarantees good work for 3-5 years. This is due to one phenomenon, which is called the degradation of LEDs. That is, the crystals gradually die off - at first they lose their brightness, and then they completely “shut up”. Another drawback is the unpleasant spectrum. According to experts in the field of psychology, approximately 80% of respondents have a negative opinion regarding the use of such lamps at home.
Difficult choice
A wide variety of lamps for dipped lighting is sometimes confusing when choosing a decent product. However, it is worth highlighting important criteria for yourself and, if possible, strictly adhering to them:
- brightness of a light stream;
- how lighting is comfortable for the eyes;
- life time;
- power usage;
- price.
При этом, решая вопрос о том, какие лампы low beams H7 are the best, you should not be guided only by cost and purchase models that are not credible due to the low price. The personal safety of the driver and his passengers depends on the correct choice. From the total number of manufacturers, there are several companies that offer products of decent quality:
- Osram;
- Philips;
- Bosch;
- Narva.
Preferring one or another brand is worthask what his reputation is. Although there are pleasant exceptions when products from a little-known company are not inferior in quality to world leaders.
Osram
It is a leading global lighting manufacturer.a name that was founded a little more than a hundred years ago - in 1906 in the city of Munich (Germany). Osram products are widely distributed among most car manufacturers, including the popular Renault concern. The high reputation of the company allows you to once and for all close the question of which low-beam headlights H7 are the best on the Ford Focus 2. The produced lamps have both standard power, and there are models in which light output is increased. By purchasing light sources for dipped headlights marked Osram, you can be sure of their long-lasting and high-quality performance.
Philips
No less well-known company in the worldspecializes in producing a wide variety of products, including halogen and gas discharge lamps. Few people know, but it is this manufacturer who is involved in the production of energy-saving lamps, which are currently very popular.
In the automotive industry, Philips isThe main supplier of lighting sources and optics for conveyors of many factories. In addition, the company supplies its products to the secondary market, significantly expanding its range of halogen, xenon and LED lamps.
Bosch
Another company from Germany, which in addition toLighting engineering is engaged in the production of other components necessary for the car. Don't know which H7 dipped beam lamps are the best? In relation to this brand, two words in German are enough - Bosch ist Bosch. What in translation into Russian means "Bosch" is "Bosch".
Narva
Among the candidates under consideration, this one isthe youngest, but this does not mean that the company produces low-quality products. The manufacturer began mass production of halogen light sources in 1969. Since that time, the Narva brand has become quite popular and recognizable throughout the world, and largely due to the optimal ratio of price and quality. Real German quality - it is fashionable to hear such a turn from the lips of many motorists, both among professionals and beginners.
