Test of automotive lamps with increased light output in the H7 base. To find out which lamps are better, the editorial staff of the AvtoDela magazine bought 10 sets of headlight lamps with an H7 base with increased light output in Moscow car dealerships and contacted the laboratory of the Federal State Unitary Enterprise "Research and Experimental Institute of Automotive electronics and electrical equipment" (NIIAAE) to conduct a test according to the method, established by the rules United Nations Economic Commission for Europe (UNECE) No. 37-03 and No. 112-00. The headlight with the lamp installed in it was placed in dark room, at a distance of 25 m from the source, the cut-off line required by GOST was set. The operator measured the illumination at control points and compared it with the requirements of the rules. The points at which the measurements were made are indicated as follows: 0-0 (Zone III) - a point characterizing the light in the zone of the vehicle in front through the rear-view mirror; B50L - a point characterizing the blindness of the driver of an oncoming car; 75R and 50R are points characterizing the illumination of the right shoulder, the far and near zones, respectively. BOSCH Plus 90 - H7 halogen headlight lamps, test MODEL FEATURES At the end of 2009, Bosch introduced its new flagship in the line halogen lamps high light output - the Bosch Plus 90 series. The Plus 90 halogen lamps are the brightest halogen headlights from Bosch. Their light output is 90% higher than standard halogen lamps. In addition, the Plus 90 lamps are innovative and create longer and wider light cones, illuminating the road much more effectively. regular lamps. Using Bosch Plus 90 lamps allows you to increase the time to make a decision, because now an obstacle on the road will be noticed earlier. The light generated by the Bosch Plus 90 series lamps is whiter than the light of standard lamps. All improvements are achieved thanks to new technologies: xenon bulb filling, optimized coil design and partial blue coating of the bulb. Illumination similar in its spectral composition to daylight, less tiring for the driver's eyesight, providing comfortable driving at night. Lamps with a silver top look the most elegant, which is especially noticeable in combination with headlights made of clear glass. The silver top and blue coating create a blue flickering effect even when the headlights are off. TEST RESULTS During the test, the Bosch Plus 90 lamp showed one of the brightest luminous flux of 1500 lm. The indicators for illumination of the right side of the road turned out to be one of the best in the test. So, for the near zone (point 50R), the illumination was 30,940 cd, for the far zone (point 75R) - 14,500 cd, with a norm of at least 10,100 cd. Safety checkpoints for dazzling oncoming and passing drivers with a margin fit into European standards: B50L - 262 cd, zone III - 475 cd.SUMMARYThe Bosch Plus 90 halogen headlight lamp in the H7 base showed excellent result. It perfectly illuminates the right side of the road, exceeding the requirements by several times, and is safe for surrounding drivers. HELLA H7 + 90% - H7 halogen headlights, test MODEL FEATURES The Hella concern is owned by Philips, and the trademark was introduced mainly to represent products in the budget segment. TEST RESULTS During the test, the Hella H7 + 90% lamp showed an average luminous flux of 1400 lm. But the indicators for the illumination of the right side of the road turned out to be one of the best in the test: for the near zone (point 50R), the illumination was 30,250 cd, for the far zone (point 75R) - 13,750 cd, with a norm of at least 10,100 cd. Safety control points for dazzling oncoming and passing drivers fit into European standards: B50L - 281 cd, zone III - 600 cd. At an affordable price, it provides excellent illumination of the right shoulder area and is safe for oncoming and passing drivers. KOITO Whitebeam III– H7 halogen headlight bulbs, test MODEL FEATURESThe Koito White Beam III lamp model belongs to lamps with high luminous efficiency. According to the manufacturer, the high-temperature lamps of the White Beam series provide twice the brightness of the glow, while consuming the same amount of energy as conventional halogen lamps. The glow temperature of the filament is higher than in standard samples. To prevent the tungsten filament of the lamp from burning out, the concentration and pressure (twice as high as in the standard one) of an inert gas are increased in the bulb. due to which Koito White Beam III lamps are absolutely safe for polycarbonate headlights of modern cars. The electrical power of the lamp is standard (60/55 W), and therefore the lamp does not emit excess heat (no more than standard lamps). Due to such technical innovations, the color temperature of light is increased to 4200 K, which improves color perception driver. The lamps are sold in pairs in a transparent plastic package with a white label written on Japanese characters. Loud numbers "135/125 W", as conceived by the manufacturer, mean increased light output of the lamps. Their electric power standard, so they can be put in the car without fear. TEST RESULTS During the test, the Koito White Beam III lamp showed the lowest result. Its luminous flux is only 1150 lm, which goes beyond the lower boundary of the corridor of 1350 lm. Thus, it is not necessary to expect outstanding values ​​​​from it in terms of illumination of control points. But despite this, the indicators of illumination of the right side of the road exceed the requirements of the technical regulations. For the near zone (point 50R), the illumination was 20625 cd, for the far zone (point 75R) - 20625 cd, with a norm of at least 10100 cd. Measurements at safety checkpoints for blinding oncoming and passing drivers gave following results: B50L - 445 cd, zone III - 1058 cd. Thus, the Koito White Beam III lamp grossly violates the rules for dazzling vehicles in front through the rear-view mirror. SUMMARY The Koito White Beam III halogen headlight lamp in the H7 base not only turned out to be the most expensive in the test - it also has the weakest luminous flux, to besides, it is unsafe to use, due to the fact that it blinds the cars in front. OSRAM NIGHT BREAKER unlimited - H7 halogen headlight lamps, test MODEL FEATURESAccording to the manufacturers, halogen headlight lamp Osram Night Breaker unlimited allows you to create a beam of light, the range of which is 40 meters longer than standard halogen lamps. At the same time, the color temperature of the light is 20% whiter than in standard lamps. This enables drivers to detect obstacles and recognize dangerous situations much earlier. The lamp has a patented blue ring coating to reduce reflected light glare. TEST RESULTS In tests, the Osram Night Breaker unlimited lamp performed well. She showed one of the strongest luminous fluxes in the test - 1500 lm. The illumination of the right shoulder was also high: point 50R - 31,875 cd (the best indicator in the test), point 75R - 16,000 cd (also the best indicator in the test). At the same time, the illumination at the glare control points of oncoming and passing vehicles B50L and zone III turned out to be higher than required by the standards, but within the requirements for serial production. SUMMARY The Osram Night Breaker unlimited halogen headlight lamp in the H7 base showed the best result and turned out to be the brightest in the test. OSRAM SILVERSTAR 2.0 - H7 halogen headlights, test MODEL FEATURESAccording to manufacturers, the Osram Silverstar 2.0 halogen headlight lamp allows you to create 60% more light than standard lamps. And the light beam from it is 20 m longer - also compared to standard products. At the same time, it is stated that the service life of the halogen lamp is doubled compared to the previous model. The use of these lamps improves the safety of driving at night by detecting obstacles earlier and increasing decision time. Osram Silverstar 2.0 lamps are ideal for use in headlamps with colorless lenses. TEST RESULTS The Osram Silverstar 2.0 lamp performed ambiguously in the test. She showed one of the strongest luminous fluxes in the test - 1490 lm. At the same time, the indicators of illumination at the control points of illumination of the right side of the road turned out to be not the highest, slightly exceeding those of standard lamps. Thus, at the 50R point, the illumination was 24,875 cd, and at the 75R point, it was 11,785 cd. Safety control points for blinding oncoming and passing drivers fit into European standards: B50L - 300 cd and zone III - 516 cd. SUMMARY The Osram Silverstar 2.0 headlight halogen lamp in the H7 base showed a low result, only slightly exceeding the illumination of standard lamps. OSRAM SUPER + 30% - H7 halogen headlights, test MODEL FEATURES The manufacturer does not declare anything special about its Osram Super + 30% lamps, except for a 30% increase in light output. These lamps are sold individually in cardboard packaging. TEST RESULTS During the test, the Osram Super + 30% lamp showed a good luminous flux of 1350 lm. The indicators for illumination of the right shoulder turned out to be one of the lowest in the test, although they exceed the minimum level of illumination set by technical regulations. So, for the near zone (point 50R), the illumination was 24125 cd, for the far zone (point 75R) - 11375 cd at a rate of at least 10100 cd. But the Osram Super + 30% lamp did not pass the safety test for other road users. If everything is fine with the oncoming lane zone of point B50L and the luminous intensity of 337 cd is within the standard, then zone III (dazzle of passing vehicles) significantly exceeds the requirement of the rules. The luminous flux at this point turned out to be 841 cd, while the value of 750 cd acceptable for serial production. SUMMARY The Osram Super + 30% halogen headlight lamp in the H7 base does not meet the requirements of European standards for dazzling the vehicle in front through the rear-view mirror. PHILIPS Vision Plus +60% - H7 halogen headlights, test MODEL FEATURES The manufacturer claims that halogen lamps Philips Vision Plus for car headlights provide 60% more light and that the driver can see farther, which increases safety and comfort. Philips Vision Plus lamps offer high performance at an affordable price.From additional benefits marketers of the company highlight the fact that the lamps are made from high-quality quartz glass, and are also resistant to UV radiation.

PHILIPS X-treme Vision +100% - H7 halogen headlights, test MODEL FEATURES Philips X-treme Vision halogen headlight bulbs deliver 100% more light and up to 35m longer beam than conventional bulbs, according to the manufacturer. Philips X-treme Vision lamps are designed with state-of-the-art technology for exceptionally bright illumination. Additional advantages of the lamps, marketers of the company emphasize that the lamps are made from high quality quartz glass, and are also resistant to UV radiation. We were baffled by the statement found on the company's website about the high level of water resistance of Philips lamps. We still didn't understand what it was about when describing the headlights. TEST RESULTS It is surprising that during the test, the Philips X-treme Vision +100% lamp showed a luminous flux of 1400 lm - lower than that of the younger model Philips VisionPlus +60% (1450 lm) and practically comparable with the obviously weaker and budget Philips Vision + 30% (1390 lm). The indicators for illumination of the right shoulder also turned out to be lower than that of Philips VisionPlus + 60%. So, for the near zone (point 50R), the illumination was 25,000 cd, for the far zone (point 75R) - 12,625 cd. Moreover, Philips Vision + 30% illuminates the near zone of the curb even better (25,750 cd). Safety control points for dazzling oncoming and passing drivers are well within European standards: B50L - 302 cd, zone III - 580 cd. SUMMARY Philips X-treme Vision + 100% halogen headlight lamp in the H7 base showed a very mixed result. Its luminous flux and generated illumination turned out to be worse than that of the younger Philips VisionPlus + 60%, which is also 40% cheaper than the X-treme Vision. PHILIPS Vision + 30% - H7 halogen headlights, test MODEL FEATURES The manufacturer claims that Philips Vision halogen headlight bulbs provide 30% more light than conventional car lamp and guarantee excellent light beam characteristics, as well as increase safety and comfort due to the quality of original components at a very attractive price. As additional advantages of the lamps, the marketers of the company point out that the lamps are made from high-quality quartz glass and are also resistant to UV radiation. And again, a strange mention on the company's website about the high level of waterproofness of Philips lamps ... TEST RESULTS In the test, the Philips Vision lamp showed an average luminous flux of 1390 lm. The indicators for illumination of the right side of the road were not the highest in the test, but exceeded the requirements of the rules. For the near zone (point 50R), the illumination was 25,750 cd, for the far zone (point 75R) - 11,287 cd, with a norm of at least 10,100 cd. Security checkpoints for blinding oncoming and passing drivers: B50L - 306 cd, zone III - 700 cd. If the first value is well within European standards, the second exceeds them, but does not exceed the deviation allowed for serial production. SUMMARY Philips Vision halogen headlight lamp in the H7 base, at its affordable price, exceeds the requirements for roadside lighting, but is prone to blinding ahead running transport.

Safety depends on the quality of road lighting when driving a car. The sooner the driver can notice various obstacles, the more time will be for the correct reaction and decision. In order to avoid any problems in the dark, you need to carefully approach the choice of headlights. Let's find out which are the best low beam H7 bulbs.

H7 standard

Such single-filament lamps are used more often for low beams.

For long range it is much preferable to use older devices of the H1 standard. H7 can be safely attributed to the group of flange lamps. They differ in a fixed distance from the flange to the helix. This ensures that the filament is in the focus of the reflector. This is important in order for the lighting to be correct. H7 dipped beam lamps must have precise geometric characteristics - this is the key to the highest quality result.

Today there are several types various devices with such a plinth. They differ from each other in production technologies, technical and lighting characteristics, as well as power indicators. The standard power that a regular H7 low beam lamp has is no more than 55 W. But there are manufacturers who make models with higher power. For example, the well-known company Narva produces products of increased size. However, it is better to use them off roads and highways. The use of such lighting devices increased power in the headlights of conventional vehicles can overload the vehicle's electrical system and damage it.

Low beam lamps H7: varieties

Among the variety, three types of these lighting fixtures can be distinguished.

So, this is halogen lighting, metal halide or xenon, as well as LED lamps. Each technology has both pros and cons. We will look at them in more detail.

halogen light

H7 low beam halogen lamps are inexpensive, have good performance and they do not require any additional equipment. By design, this is a flask made of solid or quartz glass. It is filled with neutral gases, as well as halogen vapors. Also in the design there is a filament. Today, these devices are among the most sought after. But with all their high performance and excellent qualities, there are also disadvantages. These are the high operating temperatures that accelerate the aging process. Among the advantages, one can single out excellent value for money.

Test

During the tests, the lamp in the headlight was installed in a dark room. The experts measured the illumination and compared it with the existing requirements and regulations. It was checked whether the headlights would blind other road users. Only H7 low beam halogen bulbs were tested.

Bosch Plus 90 H7

This line of lamps from a well-known manufacturer was introduced at the end of 2009. These devices are considered one of the brightest low beam sources from this manufacturer. Their light output is as much as 90% higher than that of many standard fixtures. Thanks to the use of modern innovations and technologies in the production, the products of this series give longer and wider cones of light.

Thus, the roadway is illuminated much more efficiently than regular lighting equipment. The use of such lamps makes it possible to increase the time for making a decision on the performance of a particular maneuver, because with them you can quickly see the obstacle.

The light emitted by these H7 dipped beam bulbs is whiter than standard products. With these devices, driving a car at night is much easier. This is an excellent result.

"hella"

This company is one of the divisions of Phillips. Trademark introduced for products sold at a more budgetary cost. Lighting devices of this series showed an average level of luminous flux. And this H7 dipped beam lamp illuminates the right side of the road better than anyone. This device is one of the best. Its value for money is just excellent. Proposed by affordable prices, this product illuminates the road well and does not blind oncoming drivers.

OSRAM NIGHT BREAKER unlimited

According to the manufacturer, this product is able to create a light beam with a range of 40 meters more compared to standard devices. The emission spectrum is whiter. Drivers can recognize hazards on the road earlier.

In the test, this device proved to be one of the best. Although its characteristics are on the verge of admissible - it is the best choice and maximum brightness.

OSRAM SILVERSTAR 2.0

This light source gives a glow with an intensity 60% higher than standard light sources. The light beam is 20 m longer than standard low beam luminaires. The manufacturer managed to double the service life of this product. The lamp showed poor results. It only slightly exceeds the coefficient that standard light bulbs show.

H7 low beam lamp (xenon)

These metal halide products give off a glow thanks to an electric arc that is passed between two electrodes. The bulb is filled with xenon. These modern lighting practically immune to various vibrations. The light they give out is much stronger and better, with a high color temperature.

What xenon to install on the car?

Car owners who xenon light not provided by the manufacturer, they mount the so-called pseudoxenon or xenon lamps in PTF. Well, others who have such a light can be installed regularly are often interested in what devices and kits to choose.

This beam cannot be crafted. For the manufacture and installation of these elements, high-quality equipment is used and modern technologies. You also need to have special optics.

In the domestic market, the H7 low beam "xenon" lamp is presented in two forms.

So, they distinguish between factory products from well-known and leading manufacturers and devices manufactured by specialists from Central Asia and brothers from under heaven.

Which xenon to choose?

This choice depends on several factors. The first is the budget. And here there are two options: a minimum set of a lamp and an ignition unit, or a complete set, consisting of optics, headlights and everything else.

Tests were carried out, which resulted in several brands that are distinguished by high product quality and light efficiency.

MTF Light Kit

Here are a few included automotive elements, including H7 dipped beam bulbs. There is also an ignition unit. Optics has high level coherence. There is practically no effect of scattered light during rain.

SHO-ME

This product stands out from its competitors wide range glow spectra.

Lighting devices that are produced under this brand are suitable for any car. The set includes lamps for cars H7 dipped beam, as well as for products for other socles.

APP Digital Ultra Slim

These are made in Japan. Here you can highlight the ignition unit with compact dimensions, high quality lamps, reliability, as well as a long service life of the bulb.

These are only the highest quality samples of xenon equipment. When making a choice, you need to take into account all the nuances of the market.

It is best to purchase this equipment from direct dealers. That's the only way to get quality product. The presented brands give a strong and high-quality glow, and with the right settings, these lamps will not blind other road users.

The best of the best

If we consider standard plinth H7, which low beam lamp is better, it all depends on the brand of car and financial costs. So, as a result of numerous tests and analysis of user reviews, only three leaders meet the entire requirement. These are Osram products, products from the German company Bosch of the Plus 90 series and Hella + 90 lamps.

But the service life of these lamps is very, very short. It is only seven months old. Those who have paid attention to the Koito brand should know that they do not meet the requirements stated by the manufacturer. They are much overpriced than they really are.

So, we examined the features of the H7 low beam lamp and their main manufacturers. We hope you find this review helpful.

head lights- a mandatory part of any car. Traffic safety largely depends on them. And for this reason, automotive concerns tirelessly conduct research and work to improve these lamps, work on the parameters of the light beam, improve specifications and reliability. By conducting a comparative test, laboratories determine which light bulbs are the best.

One of the most common types of automotive lighting are H7 bulbs - they appeared on the market in the second half of the 90s.

Bulbs H7 - description and characteristics

Single-filament type H7 bulbs are used in four-headlight headlights in vehicles with a separate reflector system for high and low beams. But in the vast majority of cases, with the help of H7, light of the near level is provided. For long-range, a less expensive and outdated version of the H1 is used.

In H7, which is typical for the flanged variety, the distance from the flange to the spiral is constant and fixed. This is done in order to ensure that the glow point is constantly present in the focus of the reflectors.

The test test showed that it forms right light. Based on this, it can be emphasized that the accuracy of shapes and sizes affects light and is one of the factors that determine the quality of lamps.

Lamp with socket H7 — general form

Today's industry offers motorists various modifications of the low beam H7 lamps. They may have various technology production, parameters characterizing light, and power. For H7, a standard power of 55 watts is adopted. But there are modifications of the H7 with increased power ratings. However, they are only recommended for use in off-road conditions or on closed tracks. In a conventional car, the use of such lamps will cause the system to electrical supply will be overloaded and fail.

There are the following varieties of H7:

• halogen;
• xenon;
• LED.

After conducting a test and studying the reviews, you can find each of the varieties has its own advantages and disadvantages. Let's take a closer look at what features are typical for each modification of the H7.

H7 halogen bulbs

H7 low beam halogen sources have a fairly low cost. They do not need to install optional equipment. They give the right quality light.

They consist of a container, for the manufacture of which they take carbide or quartz glass, filament and gas with halogen additives. In fact, it is by far the most widely used variant of low beam lighting today. Their most significant drawback is that they shine at a fairly high operating temperature, which strongly affects the wear rate of the optics. If we talk about the balance of cost and quality, then for H7 halogen products it is optimal.

Xenon bulbs H7

In xenon sources of near illumination H7, light from an electric arc is let in between two electrodes in a glass container with xenon. It's over modern version, which guarantees the correct white-blue light, which is comfortable for the eyes of the driver of the vehicle and does not blind those who are driving oncoming cars. Since they shine without a filament, vibration is not terrible for them - a test test confirms this.

However, xenon bulbs have two significant "minuses":

• The first is a rather high cost.
• The second is the need to install additional equipment, xenon products need an ignition unit.

They are much less common than halogens.

H7 LED bulbs

Experts evaluating the quality and performance of the lamps say that the future of car lights lies with LEDs. The test confirms the prospects of this direction. They are the most economical, durable and resistant to vibrations and shocks. The light from these lamps answers all necessary requirements, that is why the best option for lighting will be .

However, their use requires the use of special optics. Some put LEDs in regular headlights. However, this can cause problems. LEDs do not shine pointwise, so conventional headlights do not make it possible to properly adjust the light beam.

The price of LEDs is quite high. Therefore, they are not very widespread in the market. Some manufacturers have developed a design of headlights, where there is no division into light bulbs, reflectors and optics. The test showed that the light of a headlight consisting of all LED lamps is much more effective in providing a view of the road.

Selection of H7 dipped-beam lamps

When choosing H7 lighting sources, consumers often have the question of which ones are better. In this matter, it is best to consider the factors that are most important to you:

• the brightness of their glow;
• lighting comfort;
• durability;
• cost and other indicators

It is better not to pursue cheapness much, especially if it is achieved at the expense of quality. Your safety depends on how well and correctly the light bulbs in your headlights shine - saving on it is very expensive.

Luminous intensity diagram for H7 halogen headlights in the near field of the right shoulder

Diagram of the luminous intensity of H7 halogen headlights in the far field of the right shoulder.

Various manufacturers use their own methods and technologies for the manufacture of lamps. A comprehensive test evaluates their quality and effectiveness. This avoids knowingly wrong paths in production. However, the same test demonstrates that common paths may vary as a result of implementation by different manufacturers.

The most common advice in this area is to take into account the reputation of the manufacturer. However, the products of little-known companies with an unknown reputation are often inferior in quality to products from well-known brands - they almost always shine as they should.

When choosing, you need to know that, in addition to standard products, manufacturers offer options with improved parameters. However, it should be taken into account that the better one indicator, the lower the other - no one has canceled the law of balance.

Therefore, the brighter the light sources shine, the shorter their service life. Conversely, extended life lamps tend to have lower light output. Therefore, standard products are usually - optimal solution in terms of the balance of all indicators.

Conclusion

H7 bulbs are by far the most commonly used in car low beam headlights. They shine in almost all modern models. The industry offers them today various varieties- the choice depends on those factors that are most important for a particular consumer.

Often even in daytime visibility on the road can be very poor, which is why you may not notice an approaching car. In this regard, the traffic rules have been changed and today the dipped beam must be turned on while driving on all vehicles, regardless of the time of day. And these are not just wishes addressed to drivers, but a current regulation, non-compliance with which may result in a fine of 500 rubles (for more details, see Article 12.20 "On Violation of the Rules for Using External Lighting Devices").

Such requirements and reasonable meaning lead any motorist to the question: “Which low beam lamps are better to use?” To answer it, you must first understand the differences between these lighting devices.

What is the difference between lamps with different markings

Today, lamps with one or two filaments (spirals) of incandescent are produced. The latter allow you to use lighting elements for both near and far lighting, for this you just need to switch from one light to another. Single-strand analogs are more difficult to use. In more detail, there is the following classification:

• H1 - used for headlights high beam and sometimes for foglights (designed for a four-headlight system).
• Lamps in the H2 base are used for low and high beams, as well as fog lights. This type of lighting elements is almost never found today.
• H3 - only for fog lamps.
• H4 automotive lamps are used in traditional European two-headlight systems for high and low beams.
• H7 automotive lamps are also used for high and low beams in four-headlight systems.

The last two types are the most commonly used. If we talk about their differences, then H7 are single-strand lighting elements, and H4 have two spirals, but are inferior in this case in the characteristics of the new model. This is especially true for the service life (in H7 it is twice as long). And, of course, like all the lamps described above, each type has its own base design.

Since H4 and H7 lamps are most often used for low beams, we will talk about them in more detail.

The best lamps in the base H4

If we talk about which H4 low beam lamps are the best, then you should rely primarily on the power of the glow. If you do not leave the city limits, then it is better to take 60 W light bulbs, and for country trips 130 W.

Important! Lamps with a power of more than 60 W are prohibited for use in urban areas. h7 bulb

As for the choice between halogen and LED lamps, it’s worth saying right away that although LED lighting elements are highly economical, they will not work for headlights designed for H4 halogens.

Firstly, in order for an LED bulb to be comparable in light output to a halogen lamp, its size will be much larger, and if you use compact model, then from it you will get a very small light output - a vicious circle.

Secondly, if you put LED analogues in the headlights for H4 halogens, their beam will be out of focus, the light will become blurred, which, in turn, will significantly worsen the illumination of the roadway.

Thirdly, a large number of LEDs will cause the semiconductors to not cool.

Healthy! Automakers are developing special diode headlights, however, it has not yet been possible to solve the problems of the cooling system for such elements.

Therefore, in order to achieve best performance it is recommended to use halogen bulbs for cars H4 increased brightness from trusted manufacturers.

As for the H7 lamps, they also have their own characteristics.

The best lamps in the base H7

If we talk about which H7 low beam lamps are better, then today there are many modifications of this type of lighting elements. Models may differ in production technology, varieties, light and many other parameters. Only the standard power remains unchanged, which is 55 watts. However, today on sale you can also find high-brightness halogen lamps for H7 cars.

If you use h7 diode lamps in the low beam instead of halogen ones, then the problems will be the same as in the first case: overheating and the need to use special optics, since without this it is impossible to adjust the light beam.

However, LED lightening strides and develops by leaps and bounds, so the moment is not far off when it will be possible to use just this type of lamp for low beam. This is not surprising, because in the future, the H7 low beam LED lamp is much more convenient and profitable to use. Excellent light, durability and resistance to vibrations and shocks - all this characterizes lighting elements of this type.

As for low beam lamp manufacturers, it is best to buy products from trusted companies that have proven themselves in this industry.

The best manufacturers and models of H4 and H7 halogen lamps

If speak about best brands, then according to testing, the models showed themselves best:

• Koito. A Japanese company specializing in lighting technology, which produces halogen low and high beam lamps adapted to Russian conditions. Lamps Koito Whitebeam III H7 (2 pieces) now cost about 1,800 rubles, and the same model for the H4 base will cost a little less - 1,500 rubles.
• Osram. Although competitors are trying to prove that the lamps of this manufacturer blind drivers in the oncoming lane, there is no official evidence and tests to confirm this. On the contrary, Osram products stand out for their quality and reliability. The best on the market, motorists noted Osram lamps SilverStar, costing 550 rubles for the H7 base and 770 rubles for the H4.
• Philips. The eminent corporation repeats the developments of Osram and produces lamps with the same characteristics of the light beam. However, the quality of Philips halogens is also credible. A Philips Visio Plus +60% lamp with an H4 base costs 550 rubles, and for an H7 about 1,200 rubles for two jokes.
• Bosch. The Hungarian manufacturer has been famous for its quality for more than a year. Good luminous flux, providing the necessary illumination, both on the side of the road, and near, as well as distant zones. A Bosch Plus 90 H7 lamp (2 pieces) will cost about 1,400 rubles, and a similar Bosch Plus 90 H4 Lamp will cost 1,200 rubles.

Speaking of the best low beam lamps, we did not touch on the topic of xenon, and there are several reasons for this.

A few words about xenon

Halogen and light diode lamps so far they do not reach the power of modern xenon lighting elements, why not use more durable (up to 2500 hours) lamps?

Of course, xenon has one indisputable advantage. Such lamps convert only 7% of energy into heat, and halogens all 40%. This means that almost all of the consumed electricity is converted into a powerful light flux. But, alas, this is only one side of the coin. In fact, the use of such lamps is unprofitable for several reasons:

• The cost of xenon is several times higher than halogen and LED lamps. This is due to the fact that such lighting will require additional equipment (the minimum set includes a lamp and an ignition unit, the full set includes optics, a headlight and much more). Lamps of this type themselves cost about 10,000 rubles.
• Not all xenon can be used in the Russian Federation, more precisely, only the one that was installed at the car manufacturer's factory can be used. For "handicraft" Chinese counterparts, you can safely get a fine, and when passing through MOT, you will have to get rid of prohibited lighting.
• Xenon blocks use quite a lot of energy from the generator, respectively, fuel consumption increases.

In custody

Summing up, we can say that so far the most convenient and inexpensive are halogen lamps for dipped beam. When choosing them, you need to pay attention to the manufacturer and power characteristics. It will not be superfluous to familiarize yourself with the official tests that manufacturers usually provide to buyers on their websites.

Good day, dear friends, today on the agenda we will have a highly anticipated test of the brightness of the lamps of the eminent KOITO company, namely KOITO WHITEBEAM III in the H7 base.
Let's compare them with our last test winner OSRAM NIGHTBREAKER UNLIMITED.
Make the decision to buy yourself, I just show the results and speak my personal opinion, everything else is up to you!

Car lamps, despite their miniature size, are the most important part of a car. Thanks to good lighting the motorist can move without problems in any terrain. Lamps act as a safety element, illuminating the road section and part of the curb.

Also when equipping a car good lamps the health of the driver's eyes is preserved when driving at night. That is why choosing a good quality lamp is the key to safe and comfortable driving. But in which case LED 12 volt bulbs are used for cars, it is indicated

On the market there are also such as increased power. Their main differences from conventional products are:

• Great color rendering. The beam of light is amplified with the help of reflectors, but passing through the lens and headlight cap, it is scattered in space. The more powerful such a beam, the clearer, farther and brighter the lighting will be, despite the design. Therefore, such as higher power provide more efficient lighting pavement and roadside sections;
• High quality headlights, despite increased power, do not dazzle oncoming drivers. When purchasing good powerful lamps, due to their design features there is no blinding of drivers of oncoming cars (to some extent this does not apply to some models of 6000 kelvins);
• On-board voltage. The more powerful the lamp, the more load the on-board network and the car battery in particular take on. Thus, with a low battery charge, the lamps can either burn out or otherwise fail. It follows from this that using high-power lamps you need to monitor, including the condition of the battery;
• In addition to the higher lamp power with a higher indicator color temperature give the effect of xenon. This effect is due to the value of kelvins. In a car, burning lamps look attractive, but in some cases they may not meet GOST standards.

But how to install LED lamps in w5w dimensions and how to choose the right ones is indicated

Power differences

Lamps n 7, their difference from the rest and subspecies of 4000, 5000 and 6000 kelvins
The index n means the standard size of the lamp diameter.

Most small cars have lamps with a diameter of n 4. Larger size n 7 is installed on large cars and executive class cars. Size n 7 is much larger and is considered the largest standard size among mass lamps. Accordingly, the cost of such lighting lamps is more expensive compared to the size of n 4 by an average of 30%.

The price for a lamp of a well-known manufacturer is about 1000 rubles.

Index 4000, 5000 or 6000, indicated on the packages indicates the size of the color temperature, which is measured in kelvins. Accordingly, the higher this indicator, the greater the brightness of the lamp.

The highest value the brightness is considered to be 6000 kelvins, however, due to the too bright glow, there may be problems with violation of administrative legislation. Such powerful lamps have a feature - the higher the brightness, the higher the return of the blue color, which does not always meet the standards of GOST.

The higher the brightness, the more expensive the product in production, respectively, the higher the cost of the final product. Such lamps with an H7 base will cost an average of 10% more than lamps with a value of 4000 kelvins.

In terms of reliability, it is considered the best product. The only negative is the high cost (from 1,500 rubles per set), but for such a price, the consumer will receive a reliable and proven product.
