Дорожное полотно должно быть хорошо освещено как during the day and at night. Therefore, car owners are obliged to pay maximum attention to the headlights. The light bulbs in the H1 and H2 bases are hopelessly outdated. Today, they were replaced by improved modifications of lighting devices. Most often, 4 and 7 generation light bulbs are used for head lighting. They are more economical and have a long service life.
To determine which H4 bulbs are good, it is worth considering their variations. To date, there are three types of such sources of illumination.
Halogen bulbs
Now halogens are used most often.Most motorists believe the most advantageous ratio of their price and quality. Devices of this type are flasks made of refractory glass. Inside there is a halogen gas, in turn, there is a filament (coil) in it, through which voltage is applied. Due to this, the temperature in the flask rises, the gas is heated and luminescence occurs.
Halogen products with H4 base shine bright white light. There is not one thread in them, but two. The first is responsible for the main beam. The second is for the neighbor.
If we talk about which H4 bulbs are good, then you should pay attention that halogens have several significant drawbacks:
- If one of the spirals fails, then the whole light bulb will have to be changed.
- Products are very hot, so they can not be used with plastic optics.
- Lamps are quickly damaged by vibrations.
Most often, motorists are interested in what kind of light bulbs are better - H4 halogen or bi-xenon. The second type clearly wins. Consider why.
Bixenon
Bi-xenon lighting devices stronglydiffer from halogen analogues. They also represent a flask filled with gas. However, in this case, inside the lamp there are not 2 spirals, but two electrodes projecting an electric arc between them.
If lighting products with H4 base are used, then they additionally have a magnet and a special screen. Thanks to these elements switching of a distant and a passing light is carried out.
Choosing which H4 bulbs are good, you should pay attention to the benefits of bi-xenon. Such products:
- They are characterized by increased light output, which is several times higher than the same indicators for halogen glasses. Due to this, the lighted area of the roadway increases.
- Not afraid of vibrations. Due to the fact that the device does not have a filament, the products are characterized by high reliability.
- Do not heat up, so they can be installed in modern plastic lights.
However, when deciding which H4 halogen lamps to choose, you should pay attention to the disadvantages of these lighting devices:
- High cost.
- The difficulty of self-replacement.
- The need for extremely fine tuning.
Because of these drawbacks, they increasingly prefer LED lighting.
LEDs
LED lighting devices are the most promising and versatile. In the process of testing such products show the best results.
Светодиоды выдерживают нагрузки, не перегреваются and do not fail after the first bump. At the same time, they work equally well in conditions of heat and extreme cold. In addition, LED devices differ in a huge working resource.
The only drawback - the LEDs are not suitable for every optics. Since LED devices form a light beam, they require special lenses.
Nevertheless, if we talk about which H4 bulbs shine better and less often burn out, then it is worth giving preference to LED lighting.
Weatherproof lamp
Of course, every driver wants to purchase the most versatile lighting tool for a car. However, today a fairly wide selection of H4 light bulbs is on sale. Which is better?
In fact, it all depends on the frequencycar use and weather conditions. If you have to drive on wet asphalt every day in conditions of fog or rain, then it is better not to choose lamps with diffused white light. Such lighting is almost invisible in bad weather.
On sale there are special devices for suchcases - all-weather light bulbs. On the flask of these products is applied a special coloring spray, due to which the luminous flux becomes yellow. This color is clearly visible on wet asphalt, so the roadbed is clearly visible both during the day and at dusk.
Which bulbs are better: H4 or H7?
If we talk about these two bases, then we consider their main differences:
- In terms of the working life of the product, 7 modifications exceed the H4 lamps by almost two times.
- In the lamps of the 4th version there are 2 spirals installed, and the more modern analog has one.
- The seventh option is usually applied with free-form headlights.
However, there is definitely one type of devicefor lighting is very difficult. It all depends on the particular car. For example, consider the Volkswagen Transportet. What kind of bulbs are good in T5? H4 for dipped and main beam. Other modifications in this car are not provided.
Therefore, before buying a lighting element, it is recommended to check with the technical characteristics of the machine.
Now consider which H4 bulbs are good, based on their manufacturers. Below is a list of the most popular and high-quality devices.
Koito VWhite
Japanese manufacturer offers light bulbslow and high beam in the base H4. This company is famous for high-quality lighting that meets all the requirements of modern drivers. Products are great for harsh weather conditions.
Of the benefits of Koito VWhite worth highlighting:
- High wear resistance.
- Compliance with the regulations of the Russian Federation.
- Light output 55-60 watts. True, the manufacturer indicates 100 watts, but in fact it is not.
- Power and excellent light output.
- Versatility. Lamps are suitable for headlights of different shapes.
- Long service life.
Such products are the best option for budget cars.
Osram night breaker
This manufacturer has long been famous for itslighting engineering. At one time, Osram galogens were blamed for blinding oncoming cars, but the company proved that all these insinuations have nothing to do with reality. For this, independent tests were performed. Therefore, if today you ask any car owner about which H4 bulbs are good, Osram will be the most likely answer.
From the advantages of these lighting devices can be identified:
- Excellent light output. The road is well lit in all conditions (snow, rain, wet asphalt).
- The ability to "punch" fog. This eliminates the need to use protivotumanok.
- Blue light with a white tint. That is why the light beam is clearly visible on the roadway.
- Roadside lighting. Many light bulbs shine only in front of themselves, but Osram products also capture the pedestrian part.
- Relatively low cost.
Nevertheless, it is worth saying about one drawback.these devices. They often burn out for no apparent reason. However, there are also a huge number of satisfied customers who claim that these conjectures are just another trick of the competition.
Philips X-Treme Vision
Разработки этой компании и «Осрам» практически не differ, so it is not surprising that this version is very similar to the Night Breaker line. Identical colors, the dispersion of the light beam and other characteristics - all this combines products from these two manufacturers.
However, it is worth noting that Philips pays more attention to product quality, since their lamps did not receive negative feedback associated with a quick failure.
Philips lighting elements have the following advantages:
- Very high durability. At the same time lamps work well in all weather conditions.
- High quality road lighting. Even on the icy surface there are no glare.
- Clear curb lighting. According to the latest tests, the Philips X-Treme Vision line has shown the best results.
- Increased light output.
- The ability to choose the hue of the light beam from bright white to blue.
To date, Philips lamps are considered among the best, according to experts and car owners themselves. However, they will cost several times more than the Night Breaker.
Bosch Plus 90
Тому, кто не привык экономить на своем автомобиле and can afford to buy the best lighting for the car, you should definitely pay attention to the products of the company "Bosch". These lighting elements are characterized by high light intensity throughout the entire operational life. At the same time, Bosch lamps work equally well in the city and on the highway. It is worth highlighting the excellent control of the curb and the range of the beam of light.
In addition, it is worth highlighting other advantages of Bosch Plus 90:
- The highest luminous efficiency (compared to the analogues described above).
- Unique light beam control technology. No one has yet succeeded in repeating this achievement of Bosch.
- Warranty on all bulbs.
- The highest intensity of illumination of the roadway.
At the same time the lamps do not blind the other participants.road traffic, which is also an important advantage. However, such a list of advantages and the complete absence of negative sides will have to be very expensive to pay. However, if you are trying to determine which H4 bulbs are good, the photo will help in choosing.
Summing up
Today in the market you can find a huge amountlamps for the head light of the car. It all depends on the amount that the car owner can afford, as well as the driving conditions. Need to take into account all the nuances. It is also necessary to look at the documents on the operation of the vehicle and to clarify what kind of base can be used for headlights of a particular brand of car.
Save on security is not worth it. From the lighting of the roadway in the literal sense of life depends on the driver. Therefore, it is best to buy the best light bulbs.
