The H4 12v lamp is a bright halogen light source with a worldwide P43t-38 base. It is used with the H4 headlights, which are distinguished by an improved connection element and a special design of the optics. Today, halogen lamps of this standard are rightfully considered one of the most popular among Japanese, Russian and European motorists. H4 lamp (12V, 60 / 55W) is produced in variousversions, each of which has unique operational features
The greatest demand in Moscow is for white H4 lamps, which are versatile and practical, demonstrating equally high efficiency both in the city and on suburban roads. The price of standard lamps is the lowest, which makes them the choice of those drivers who do not have any special preferences and just want to distinguish normally at night. However, for some drivers in Moscow, standard lamps are not suitable.
Auto lamps H4
Along with the standard ones, you can also purchase specialized ones, which, for example, include especially bright H4 lamps. They have a greater illumination range, which is especially important when driving in a straight line. That is why super bright bulbs are used mainly by truck and bus drivers who make intercity flights.
The lamps for the H4 car, which have an increased luminous flux, are also progressive ones. These lamps produce more light, giving out a richer light spot. It is better to distinguish between small objects, impact on which can damage the suspension of a modern car. If you often come across stones and potholes on your way, you certainly need bulbs of increased light output.
The H4 60 / 55W heavy-weather lamp features a yellowish glow that is better visible in rain and snow. This is where its technical differences from the standard H4 12V lamp end. The cost of this category of specialized lamps is equal to the cost of standard light sources, so that most drivers are willing to purchase them for use in winter and off-season.
As you can see, the best H4 bulbs can come in quite a few designs, each of which will be of interest to a specific group of drivers. It follows from this that you need to choose halogen bulbs seriously, not relying on the eternal maybe. The need for careful selection applies not only to the lamps themselves, but also to the headlights in which they are used.
H4 low beam and high beam
H4 headlamps should be used with special headlamps designed for the performance of these light sources. On the other hand, for this purpose, you can convert any other headlights, even those that are not intended for halogen at all, but the effect of the vaunted halogen bulbs in this case will be about 30-50% of the possible.
When buying quality Hella branded H4 90 lamps, it is simply stupid to save on headlights. They are a single whole with the lamps, which means that duplicates are indispensable here. To see the road as fully as possible, you need original headlights that will create a wide enough light spot and orient it in an optimal way, simultaneously ensuring the clarity of the boundaries of the illuminated zone.
It should be borne in mind that the headlights of the H4 standard are not intended for separate installation of high-beam and low-beam lamps. H4 is a standard for double filament halogen bulbs that are capable of switching between low and high beams. That is, instead of two different types of lamps, you can use only one - a universal "near-far" lamp with two filaments in one bulb!

The overall dimensions of the lamp are fully consistent with the description:
The connector, standard for the H4, is carried out on the cord:
Passive radiator for cooling lamps:
Each lamp has six low-beam LEDs and 6 high-beam LEDs:
The low-beam LEDs have a reflector, as in halogen lamps:
This completely repeats the design of LED lamps:
Compare yourself:
True, Philips has the driver placed on the cord, and not inside the radiator, where it is exposed to excessive heat.
Why was this design chosen? The fact is that the headlamp will be able to work correctly only if the location and size of the LEDs completely repeats the location and size of the spirals of the halogen lamp:
But such a seemingly similar construction will not work correctly:
Due to the fourth LED, the luminous flux in the headlamp will be incorrect, since the length of the four-LED bar is longer than the normal coil.
Let's remember how a headlight with H4 bulbs works.
Low beam:
To prevent dazzling oncoming drivers, the dipped beam is placed slightly in front of and above the focal point, and shielded with a special cap inside the bulb, using only the upper half of the reflector.
High beam:
The high beam filament is located in focus and illuminates the entire surface of the reflector.
And because of such design features of headlights with H4 lamps, many indiscriminately hate all LED lamps that they blind, without even trying to figure out the issue.
Here is the main culprit for this opinion:
Such a lamp will poorly illuminate the road and blind everyone, if you still do not understand why - look again a little higher, at the design of the headlight. No explanation is needed here.
The lamp in question uses small LEDs made using the Chip-Scale Package (CSP) technology, as in Philips lamps. None of the lamps have specific brands of LEDs.
The operating voltage range is indicated on the lamps from 9 to 32 volts:
Let's start disassembling.
Unscrew the two screws and remove the reflectors:
Removable LED plates downwards:
Thermal grease is present in excess.
Driver:
Connect the lamp and turn on the low beam:
The consumption of a 12 volt cold lamp is 1.519A:
At 14 volts, on average, as in the car's wiring network - 1.260A:
We switch the lamp to the high beam:
Consumption on a cold lamp at 12 volts is 1.456A:
At 14 volts - 1.288A:
At 24 volts - 0.745A:
With warming up - consumption begins to fall. At 14 volts - already 1.099A:
The maximum I managed to heat the lamp lying on the table to 100.2 degrees:
Moreover, it doesn't matter whether the low or high beam is on. LEDs and their number are the same.
But in a headlamp, the lamp will work in more severe conditions. It is difficult to imitate them, but I tried to get even a little closer to them and put the switched on lamp in a closed empty box from under the same lamps:
Where the lamp worked for an hour. The temperature seems to have stopped rising as the current has stopped falling. At the same time, the lamp consumption was 0.701A at 14 volts:
At the same time, the lamp warmed up to 106 degrees:
Given the high temperature, it will be difficult to tell what the actual lifespan of these lamps will be. And it's not about passive cooling. Active is not better, considering the conditions under which the lamp is used, which is in a closed volume, the fan will not live there for a long time and will die before the lamp and the cooling will become much worse than passive.
Well, let's start installing lamps in the headlights:
The headlamp mounting plate has a bayonet mount and can be easily removed from the lamp:
We get to the headlight: 
Remove the protective cover:
We snap off the mounting bracket and take out the lamp:
Halogen lamp next to LED:
We insert the fixing plate with the LED lamp into the headlight and fix it with a bracket:
And we insert the lamp itself into the plate, and turn it:
We connect the power block:
We put the block on the side and close the headlight cover:
It remains to wait until darkness.
To begin with, I left a halogen lamp in one headlight, and an LED in the second. As darkness fell, I measured the brightness in the brightest spots on the wall. The headlights are located at a distance of about 2.5 meters from the wall.

I made a small video demonstrating the work of the headlights, including during a short trip:
I originally intended to use these lamps to illuminate the garage. But now I'll leave them in the headlights for now. I'm curious to see if anything can be seen on wet roads at this color temperature. Although with halogens on a wet road, I had to additionally turn on the foglights in order to see the pits and bumps on the off-road roads. The lighting is frankly weak ... But how these headlights shine on a wet road, I can hardly see before October. And it will never be too late to put them in the garage.
Thank you for the attention.
The product is provided for writing a review by the store. The review is published in accordance with clause 18 of the Site Rules.
I plan to buy +18 Add to favourites I liked the review +11 +25Summer begins, and with it my tests of LED lamps begin. In this post I will tell you about H4 LED bulbs designed for car and motorcycle. These are the first lamps I have tested that have a shutter, due to which the light-shadow border of a given low beam lamp should be identical to a halogen lamp. I have been trying for a long time to get lamps of this type for my tests and finally it worked out. Read more about these lamps below.
First, as usual, about the packaging and packaging. For the convenience of conducting tests, I signed contacts on one lamp, please do not pay attention to this. The lamps are delivered in a hard white cardboard box, inside which are two lamps and instructions with a piece of paper of the store's logo. In the manual, there are characteristics and several pictures with recommendations for installing these paws. Pay attention to the type of dust cover for the H4 lamp, it does not completely cover the lamp and there is enough room for air intake. Further, when I install my boot, I will say a few more words about this.
The lamps are made in an aluminum case, which is also a radiator. There is a fan inside the lamp housing. At the top of the lamp, there are LEDs on both sides of the printed circuit boards.
The five SCP LEDs under the shade are to follow the dimensions of the halogen bulb's spiral. These five LEDs are responsible for the low beam. Usually, in such lamps, 3 or 4 LEDs are installed under the curtain, in this case both the curtain and the LEDs themselves take about the same space as the spiral of a halogen lamp and its curtain. Here, both the spiral and the curtain are slightly larger than that of a halogen lamp. Below, a large LED is responsible for the high beam.
The store says that in this lamp, the CREE-XHP-50 LED is used as the LED responsible for the high beam, the same marking is indicated on the printed circuit board on which it is located. True or not, I will not argue, but I will still give a link to the characteristics of the XHP-50 LEDs. Datasheet XHP-50
But according to the seller, he contacted the manufacturer and was confirmed that the CREE LED was being used. But dipped beam diodes are not critical.
The store declared the following parameters:
Power consumption: 40W
Luminous Flux: 8000LM
Working Voltage: DC 12-24V
Protection grade: IP67
Color Temperature: 6500K
LED Life Time: 50000H
The dimensions of the lamp are slightly larger than the standard halogen. Its length is 101.2mm. In this case, the lamp has a weight of 55.2 g.
Usually, such lamps have a very wide range of operating voltages, so I assumed that 24V is not the maximum allowable operating voltage, but the voltage of the on-board network. Therefore, further, when measuring the power consumption depending on the voltage of the on-board network, I tested the lamp in the range from 6 to 30V. I summarized the measurement results in a table.
From the table you can see that the average power consumption for both low and high beam is almost the same and is approximately 24W.
For clarity, I built graphs using tabular data. The X-axis is the voltage in Volts, and the Y-axis is the power consumption in Watts. The red line corresponds to the low beam, the blue line to the high beam.
The next thing I did was measure the maximum temperature of the LEDs in the lamp and plot the heating curves. During the operation of the LEDs responsible for the low beam, their maximum temperature was 125.1C °. The maximum temperature of the LEDs responsible for the high beam was 100.5 ° C. This can be seen in the following thermograms. I really don't know why lamp manufacturers allow such a high operating temperature. But on some Russian-made lamps, the seller openly said that the crystal temperature during operation was 135 degrees (I don't remember the exact value now, but it was about that).
During testing, the lamp was in a small cardboard box, in size, roughly framed by the interior space in the headlamp.
In the following graph, you can see the lamp heating process. The tests were carried out at a voltage of 14V. We see that the lamp reaches the steady state temperature in about 8 minutes.
I will test the lamps on a motorcycle. And these are the first LED bulbs I tested that I was normally able to install in my headlight. Usually either the lock was not fastened, or the anther was not worn, but more often both of these shortcomings were present at the same time. I did not find such problems here. But to install these lamps, I still had to remove the front plastic from the headlight.
I will say right away that you should be careful with the boot. It is assumed that air intake will be carried out through the slots in the rear wall of the lamp; if they are closed with an anther, then the cooling efficiency will decrease and the temperature of the LED crystals will increase. However, the situation can be partially saved by the holes located around the perimeter of the lamp housing.
Usually, in such lamps, the fan is installed in such a way that the air is blown out from the inside, here the opposite is true. I thought, since the lamp is new, and only just appeared on sale, it might be possible to assemble it with a mistake. To which the seller told me that there was no mistake and sent a photo:
In order to compare the brightness of an LED lamp with a standard halogen lamp, I will compare the illumination produced by these lamps.
In the following photo, please ignore the difference in lamp brightness, the photos were taken with different camera settings. The photo settings were chosen based on ensuring good readability of the light meter parameters. But then in all the other photos where I test the high and low beam, I took pictures everywhere with the same ISO, shutter speed and aperture values.
We see that the LED lamp is much brighter than the halogen lamp. Then, as usual, I was going to look at the light-shadow border and saw that it was finally there.
Just in case, to confirm that I am not embellishing the picture when testing the lamps, I will give links to the originals of the photographs.
1. First picture
2. Second picture
Therefore, I decided to go to the inspection station and test the lamp on specialized equipment.
My headlight is tuned for a halogen lamp, if you just replace it with an LED one, then the light-shadow border turns out to be slightly raised up. As you can see in this photo (just in case, I attached a photo from two angles). According to an employee of the technical inspection station, a headlight with such a lamp can be adjusted.
In the next picture, I compared this LED lamp with a standard halogen lamp when working at high and low beam.
For completeness, a video with an example of the operation of two lamps, LED and halogen, can be seen in the video version of the review, just below. If you have read the review, then you can safely rewind the video for a time of 3:50.
Despite the fact that the light-shadow border repeats the light-shadow border of a halogen lamp, I would recommend installing such lamps only in those headlights whose reflector is designed for installing LED lamps in it.
Well, as usual, the video version of the review:
At the time of this writing, the price of lamps was about 2000r per pair.
Link to lamps
That's all for me.
I hope the review was helpful to you.
LED lampH4 N1- LED are intended for the organization of head lighting. They use an advanced type of radiator made of aircraft grade aluminum. It helps to dissipate heat more efficiently and increase the service life. Products are a modern alternative to incandescent lamps.
Modern LED lampH4 N1- LED They are very popular among car owners - they are reliable, compact and allow you to get bright lighting. When developing the model, the designers managed to reduce the length of the body, improve focusing and greatly increase the efficiency. Lamps can be effectively used as high beam, low beam and fog light.
Key advantages of LED lamps
- Optimal focusing. This is achieved due to the small size of the LEDs and their arrangement, like a filament. As a result, it is possible to achieve excellent illumination and not blind the drivers of oncoming traffic.
- Lack of ultraviolet violet.
- High heat dissipation rates. A copper core is laid from the LEDs to the radiator, thanks to which heat is dissipated in a timely manner and overheating is prevented, increasing the service life of the equipment.

Automotive H4 N1-LED lamps help you get the desired level of low and high beam. Having become acquainted with their features, many drivers give their preference to them.
H4 LED bulbs are used in two-headlight systems, their main purpose is the headlight of the car (headlight). The design provides for diodes that perform various tasks. Due to this, LED bulbs in this design are used in the organization of low and high beam. You can conduct your own test of different lighting elements or use proven information about the operation of the main types of auto lamps.
Design and principle of operation
In addition to a certain number of light-emitting elements, the design provides for a cooling system: a radiator + fan, as well as an H4 base. As a result, LED Headlight H4 bulbs are quite massive.
The main thing, when choosing a lamp, is that their dimensions correspond to those of their halogen counterparts.
But, the main thing is that their dimensions correspond to those of their halogen counterparts. The diodes are positioned differently than the filaments in the "halogen", which provides a slightly different effect when lighting.
The principle of operation of LED Headlight lamps is to obtain light energy by converting an electrical equivalent. When the main beam is turned on, all light-emitting elements provided in the design are used.
For the dipped beam, only part of the LEDs are used. Accordingly, the main area of application of LED Headlight H4 is the organization of automotive lighting, in particular, low and high beam.
For installation instead of "halogen" it is important to select the size of the light source as accurately as possible. But today there are optical systems designed specifically for LED lamps.
Types, technical characteristics
The main differences between LED Headlight H4 light sources are: the shape of the product, the type of light-emitting elements, their number and location, as well as the type of cooling system. As for the last of the named parameters, there are bulbs with active and passive heat removal.
China 2015 G9X Model Passive Flexible Ribbon Heatsink
The difference between the two lies in the presence of a fan. The shape of the LED headlight H4 can be different: with 2-3-4 edges, which determines the way the diodes are placed. There are flat and cylindrical products, in each case the light-emitting elements are located differently, which is influenced by their number and size.
Models with active radiator cooling: this makes it possible to use powerful LEDs to illuminate the road
However, tests show that not all designs of such light sources are equally effective. The closest to the real lighting, similar to the light border with "halogens" are lamps, the chips in which are installed in the same way as the filaments in halogen analogs.
CREE manufactures five series of high-power LEDs, different in design and type of crystal used: XR-C, XR-E, XP-C, XP-E and MC-E.
Also, in some models, a so-called shutter is installed on one of the diodes, due to which, when the dipped beam is turned on, the desired light border is created.
The number of light-emitting elements can be different: from 2 to 18 pieces, and the type is usually represented by the following options: SMD 2323, SMD 5050, CREE (with different parameters). The power varies from 4 W to 50 W, which is determined by the type of diodes used in LED Headlight H4 bulbs and the cooling system. More powerful chips and forced ventilation increase not only the level of the generated load, but also the cost of such a product.
In addition to the power value, the lighting element in this version is characterized by other parameters:
- power supply (12/24 V);
- luminous flux: a level of 1,000 lm is sufficient for a low beam, 1,500 lm for a high beam, in addition, H4 LED headlights are capable of providing a much higher radiation intensity;
- type of diodes, usually the manufacturer indicates the brand CREE, SMD, less often parameters are also written, for example, 1512;
- color temperature - for sources of this design, the normal range is 4,000-6,000 K;
- degree of protection;
- temperature range during operation of the LED headlight H
Quite often, instead of chips of well-known brands (for example, CREE), unnamed analogs are installed. A fake can be distinguished by visual signs: the second option is usually characterized by non-standard sizes: larger than that of the original.
More on the pros and cons
Undoubted advantages: a long service life, a noticeably lower level of load with a very bright glow, when compared with "halogens". LED light sources do not require maintenance or special maintenance other than ensuring normal working conditions. In particular, long-term operation can be achieved by equipping an efficient heat outflow system. In some versions, active cooling is already provided, but such kits are much more expensive than conventional lamps.
However, there are drawbacks, for example, the changed parameters of the luminous flux created by the headlamp optics: the test shows a less pronounced light border, excessively bright light, which may indicate an incorrectly selected lamp. The reason for this lies in the variety of versions of light bulbs, in each of which SMD, CREE diodes are arranged individually. And additionally, LED headlight H4 light sources can have larger dimensions than "halogen" ones. This nuance is especially relevant when choosing a lamp to replace the version with a filament.
Criteria for choosing an autolamp based on diodes
The light source must match in terms of radiation intensity so that the high and low beam provide illumination with the parameters required for these optical systems. Diode bulbs are the most economical type of lighting element, respectively, the power in this case will be less than that of "halogen" and other types of analogs.
The electrical characteristics of the power supply (current, voltage) are also taken into account, they must correspond to the connection parameters in a particular optical system.
Further, attention is drawn to the arrangement of the chips, their type (CREE, SMD). The test shows that the closest in characteristics is a lamp, the diodes in which are installed in the same way as two incandescent bodies in a "halogen".
The color temperature is also taken into account, this parameter is responsible for the shade of the radiation. Again, the most preferable option can only be determined by doing a practical test using several types of lamps.
Overview of light sources from different manufacturers
When choosing an LED lighting element, you should give preference to products from reliable brands, for example, Osram, Philips, Koito. Such products serve for a very long time and do not raise questions during maintenance due to the correspondence of the lighting parameters (brightness level, quality of the light border of the dipped beam). The test, which was carried out many times by different users, confirms this. Issue price: 500-3,000 rubles.
If we consider the products of MTF, General Electric, then when the head light is turned on, the brightness level interferes with oncoming and even passing vehicles while driving on the road. Any test will give similar results, which is due to the design features of these bulbs.
As for cheap Chinese products, which usually do not have a name, in this case one cannot count on the compliance of the declared parameters of the light source with the real characteristics of road lighting. In addition, the test of some light bulbs also reveals a difference in the dimensions of the chips, which indicates a fake of the eminent analogue of CREE.
There is one more feature that confirms that you buy better proven products of well-known brands. It lies in the difference between the crystals used in the construction of light bulbs. Thus, reliable structural elements (CREE) are made with high quality, as a result, natural processes of crystal cloudiness occur only after a long period of operation.
