H4 LED bulbs that could

I have long been thinking of buying LEDs in the headlight, but everything that came before this was disheartening - some idiotic fans and nameless Chinese LEDs ... And in the summer of 2016 I came across this.
These lamps are essentially a Chinese free copy. Philips LED H4 X-treme Ultinon, and the Chinese even corrected the kosyachki phillips. Why exactly these lamps? And for a combination of factors: The lamps are decently made, the driver and the lamps are collapsible and, in theory, maintainable. The design uses top-end Lumileds Luxeon ZES LEDs, the geometry of the LEDs and the reflector — repeats the standard halogen as much as possible, the power driver is present and executed as a separate unit, the lamp cooling is passive, in the form of flexible copper belts of a decent area, allowing you to remove radiators into the headlight housing, pull it out by cutting a gap in the rubber plug. These design features, including the lack of a fan, have suggested that this generation of LED lamps is already able to shine correctly, brightly and for a long time.
So, the goods are delivered in a rigid cardboarda box inside which, in the cells made of polystyrene foam, are lamps and drivers. So, despite all the efforts of the Russian post on the box, the contents did not suffer at all.

Goods purchased for their grandmother.

Here it is, my charm ...

LEDs are already familiar to us from the P21W lamps,however, here they shine 2-3 times brighter. Apparently, in P21W lamps, the operating current is significantly underestimated, so that with such a small radiator they would warm up within reasonable limits. Probably the LEDs are here, after all - the first generation Luxeon ZES.

As you can see, the geometry of the light source is as close as possible to the filaments of the halogen lamp.

Lamps are mounted quite simply. If you change ordinary lamps without any problems, then these problems will not arise. Although, if you want to place all the components inside the headlamp, it is easier to remove the whole headlamp. That's exactly what I did. From the point of view of the thermal regime, this is not the best option, but there is no need to cut extra holes in the headlamp, it remains a completely regular look and, if necessary (for maintenance, for example), the lamps change to regular halogen in 5 minutes. In general, I measured the temperature after 30 minutes of operation - on the LEDs + 125 ° C, on the radiator 50-60 ° C. The manufacturer claims the operating temperature of the LEDs is up to + 135C, so I found this mode satisfactory.

Lamp instruction

I want to reassure Paranoikov right away - lamps in this form have been working daily since September 2016. and there are no problems with them. And according to customer reviews - there are practically no failures.
The light-shadow border and the far-near modes of operation can be seen in the video below.

Here it must be borne in mind that the left headlight is the original 10-year exposure, and the right head is a shitty non-original, but new. Hence the slight difference in brightness and geometry of the headlights.
A short video showing the operation of lamps on the road.

The lamps are gorgeous. Of course, they are far from good linzed xenon, but they have gone very far from ordinary halogen. Compared to the Osram NightBreaker Unlimited, the lamps give less light in the near area of ​​the bumper, but noticeably more in the far area. In this case, the result is a more uniform lighting that improves visibility, without a bright light spot in front of the bumper.
Let's try to look for conditional flaws.
1. Snow / ice on the headlight does not melt. Before you turn on your neighbor and after a couple of minutes everything melts away. Now you have to clean it regularly.
2. You can not turn on the diodes of the far and near at the same time, even for a couple of seconds. There is such a function in a car and it works normally with halogens, but here the driver includes either near or far diodes, but not both groups at once.
3. 6500K - although the diodes are not cyanotic, the light in urban artificial lighting is not very contrasting. Well, on wet pavement is not very. However, almost everything on it is not very good.
4. A greater unevenness of illumination compared to halogen - on the illuminated surface, if you look closely, you can see the gaps between the LEDs and the LEDs themselves, etc.
5. Formally, these lamps are not a proper light source for a halogen headlamp and theoretically, you can stick to the article “for collective farm xenon”. Although in practice, working LED lamps look quite normal, with STG and jackdaws, and if they inspire traffic inspectors, then only to the questions - why does it shine so well? And where can I buy it?
6. Are a little expensive. For this money, you can buy two sets of Osram NightBreaker Laser or Unlimited and ride quietly for 3-4 years. A undemanding user and standard bulbs of 150 rubles / pc. enough for the whole life of the car. But diode lamps, if they last 3-4 years, then by this moment they’ll become morally obsolete, because there will be new LEDs - smaller, better, brighter, more energy efficient. So the savings due to the large resource - it is only in theory and advertising booklets. You need to clearly understand - in the financial board, these lamps will never pay off. But they are worth it - I replaced them with Osram NightBreaker Unlimited and did not regret it for a second ... Why? Well, I have not yet met people satisfied with the headlights on H4 lamps. The lamp in the headlight is single and at the same time it can work either near or far. As a result, the high beam on the C grade and the dipped - so-so. In separate optics, you can turn on both the near and far, and here the only option is to achieve suitable light - "reinforced" halogens or such LED lamps.
And by the way, the P21W lamps reappeared On Ali for 1175 rubles.
