H7 diode lamps for low beam cars: a motorist's encyclopedia

Every car enthusiast wants his vehicle to stand out from the rest and have an attractive appearance. For this, some motorists perform entire tuning operations, installing body kits, fashionable wheels, doing airbrushing, while others simply put H7 diode lamps in the low beam headlights. It is about the LEDs in this article will be discussed.

Pros and cons of LED low beam headlights

To date, there are two types of LEDs with an increased effect of increased dipped beam brightness - these are H4 and H7. Led bulbs of type H4, that is, xenon, are used in vehicles in which the design of high and low beams is combined. As for automotive LED lamps H7, their use is relevant in the headlights of cars, characterized by separate designs of far and near views. If you are interested in led, then you will certainly be interested in the benefits that can be obtained as a result of their operation.

Recently, more and more Russian motorists are choosing led diode lamps, since they have the following advantages (the list of advantages and disadvantages was compiled as a result of tests of diode led bulbs with an increased brightness effect):

Profitability. As a result of the fact that LED light bulbs are characterized by low energy consumption, their operation contributes to the economy of work. Accordingly, when using a module of LED bulbs with an increased brightness effect, as shown by the test results, the driver can save battery charge, as well as a certain amount of fuel.
Increased service life. According to reviews and test results, unlike halogen and xenon H4, led diode bulbs have an extended service life. Accordingly, buying a set of LEDs, the driver can save a little.
Ability to function at any temperature. Unlike xenon H4, the test showed that LED diode bulbs work without problems, and most importantly, they function stably in conditions of any temperature conditions - from minimum to maximum.
Possibility of use in plastic headlights. As a result of the test, it turned out that led diode bulbs with an increased brightness effect can be used in plastic headlights, since they practically do not heat up during operation. As the reviews show, the use of H4 xenon lamps is not always appropriate in this case.
Providing a lantern with a stable light beam. Both xenon and led diode bulbs with an increased brightness effect make it possible to provide a car low beam lamp with a stable light beam. Comparison of xenon H4 and led diode bulbs H7 was made during the test.
Eye pleasing light. In general, LED diode lamps have a pleasant and comfortable white light.
The motorist has the opportunity to create adaptive lights. As the test results showed, this can also be done for H4 xenon elements, but the installation procedure will be more complicated, and in general it will come out much more expensive. As for halogen bulbs, this will be impossible in principle.

Both xenon H4 and the best diode led lamps have certain disadvantages, which we will discuss below:

The cost of the best LED module kit is quite high, so not every car enthusiast can afford such optics.
Even a set of the best lamps can hardly give an accurate light. As the test results, as well as feedback from motorists, show, the luminous flux from the device is directed downward. Accordingly, the illuminated distance in front of the vehicle, unlike H4 xenon lamps, is halved. To correctly install and adjust the optics, it is necessary to use lenses specially designed for this.
If you buy a kit with a module that is not the best LED, you may encounter the problem of poor device assembly and lack of protection. As a result of the lack of protection, they will have poor heat dissipation, which will lead to overheating of the element and its possible flickering.
As the test results showed, when buying a set of H7 automotive LED lamps in the low beam headlights, you may encounter the problem of different light flux directions. Sometimes in one set there are elements in which the diodes themselves are installed unevenly. Accordingly, during installation, they will shine differently.
When buying a kit, it is not necessary to pay attention to the brightness level. As the reviews show, Chinese manufacturers often write large numbers on packages to interest the consumer. But in fact, the brightness level indicators usually rarely correspond to reality.
When buying a set of devices, be prepared to face the problem of lack of focus as a result of the fact that the LEDs themselves are not installed correctly. In this case, it all depends on the manufacturer, but today it is the Chinese manufacturers that dominate our market.
In fact, the power of the optics elements for the dipped beam can be much higher than stated, especially since an additional driver will be used (the author of the video is sandronovecento76).

Characteristics of H7 diode light sources

LED automotive lamps of the H7 type are designed for operation, as can be seen from the photo, in headlights with four autolamps, that is, in optics, where the high and low beams are separated from each other. High-quality xenon H7 allows you to provide a constant, and most importantly, a constant level of distance from the flange itself directly to the light component. The latter, by the way, as can be seen from the photo, is used instead of an incandescent filament. These autolamps allow you to provide the right light, which will provide the most optimal view of the road surface and will not blind drivers driving towards you.

It is necessary to make a reservation about the last parameter. You will not blind the drivers driving towards you only if you install a set of high-quality car lamps on your car. Trying to save money, many motorists today buy cheap optical elements, as a result of which they bring discomfort to other drivers. A system of matrix diodes is used in the device of a set of high-quality autolamps - thanks to this, energy resources will be used more rationally. It should also be noted that H7 diode autolamps can be used not only in low beam optics, but also in fog lamps.

Now let's move on to the main technical characteristics of the sources. When buying car lamps for your vehicle, the driver should focus on certain parameters. If these indicators do not correspond, then it will be impossible to achieve high-quality road lighting.

So, what are the parameters in question:

the brightness parameter for the high beam must be at least 1500 lumens;
the brightness level for the low beam must be at least 1 thousand lumens;
as for power, this indicator should be around 14 volts;
in order not to encounter possible problems in the future, it is advisable to use optical elements equipped with a special cooling system (the author of the video is the HID channel).

Features of choosing LED bulbs for low beam headlights

So, if you have a need to purchase a set of high-quality LED bulbs, then in order to purchase the most reliable optics, you need to consider some requirements. As you might have guessed by looking at websites with photos and videos, as well as offers from various stores, the market currently offers customers a huge range of such products. How difficult it is sometimes to choose a quality product that will provide optics with high-quality lighting.

Therefore, the main thing is not to make mistakes when choosing. To do everything right, you need to know certain selection criteria, you should definitely familiarize yourself with them. Below is a basic list of parameters that you need to pay attention to when purchasing H7 type LED bulbs.

Firstly, we are talking about compliance with all requirements, norms and standards. Before buying, you should carefully read the service book for your vehicle. Often, in the operating instructions for a car, manufacturers indicate all the points that a motorist should be aware of when choosing optics or light bulbs. The main thing is that after installing xenon in the vehicle, problems with power and system overload do not start, otherwise the xenon will have to be removed. It is very important that the technical parameters of the purchased optics correspond to the parameters of the car (the author of the video is Test Lab Autolamp tests).

The level of brightness of the light, as well as the color of the spectrum. As you might guess, it is desirable that the brightness level be the highest. The choice of brightness level is also carried out in accordance with the requirements of the vehicle. As for the color of the spectrum, everything is individual here - choose the color to your liking. It all depends on the preferences of the motorist, but usually our motorists choose either white xenon or blue.
Beam size. This indicator is one of the main ones, since it will depend on it how much the road will be illuminated in front of the vehicle. The larger the light beam, the better the lighting will be.
Light bulb stability. As you understand, in this case, much depends directly on the manufacturer of the optics. Before buying, we recommend that you carefully read the reviews of motorists left on the Internet. If a particular model is not of particularly high quality, and you notice negative reviews about it, then it would be better to refrain from buying.

Xenon car lamps are a promising type of car lighting, but when buying devices for yourself, you should not be guided only by the manufacturer. After all, everyone knows that among well-known brands, defective products periodically come across, and the Chinese have recently begun to make more or less high-quality optics. But usually well-known companies value their reputation, so they usually have much less marriage.

Of course, when buying components, you should not be guided by price alone - you should not expect good road lighting from cheap lamps. The choice of LEDs must be approached with all responsibility, since the illumination of the roadway at night determines the safety of the motorist as a whole. So by opting for more expensive and high-quality optics, you can be sure that the visibility of the road surface will be at a high level at night.

Conclusion

LED elements for optics are characterized by high efficiency, ease of use, as well as a high service life. In addition, due to their excellent performance, LEDs are becoming more popular. However, the main reason why diodes are not yet in every car is the high cost of the elements. Moreover, in order to achieve the desired effect, the optics of the vehicle must be additionally equipped with lenses, otherwise it will be impossible to adjust the light.
