Top 10 H4 LED Bulbs

The Vizant brand has become popular due to affordable prices for good quality automotive electronics. It also offers a wide range of serial car lamps with LEDs from well-known manufacturers. So, the J1 series is the next generation of N1 bulbs, which at one time earned the glory of bright and reliable light sources. The developers improved its light characteristics and worked on the dimensions: the lamp began to shine brighter by 500 lm, decreased in diameter to 42 mm and shortened to 83 mm.The area of ​​the radiator faces was also increased, respectively, the heat removal from the ICE elements became more efficient, and the lamp could theoretically serve 50,000 hours.

What is the performance of the device in practice, it was not possible to determine - there are too few reviews on the network. However, it has another advantage - a scale applied to the base with 360 ° marks. It greatly facilitates the adjustment of the angle of inclination of the lamp in the headlight, which is necessary to obtain an even cut-off line. Also pleased with the declared degree of moisture and dust protection IP68. According to the norms, it indicates complete tightness, and the manufacturer confirms the ability of the lamp to work in conditions of high humidity.

H4 LED lamps are most often produced by little-known Chinese brands, so they are easy to find on Asian marketplaces. But there are also Russian companies in the list of manufacturers. Yes, these light bulbs are also produced in China, but under strict supervision. High-quality materials are used here, so the service life, if it does not exceed the declared one, but strictly fulfills it.

Lamps with forced cooling and an aluminum radiator. Heat dissipation is excellent, and the cooler rotation speed can be adjusted. The main thing to understand is that such a lamp will not fit into all headlights. The connection here is standard, H4, but the lamp itself is one-piece, so it needs a lot of space behind the block. Be sure to check this point before buying. What's more, it's easy. Lamps are easy to find in a regular retail store or marketplace. But it is recommended to study the product before buying.Judging by the comments on the network, marriage here, although not regular, does occur.

Gone are the days when only premium class cars flaunted LEDs. Today, stylish headlights with LEDs can be equipped with even a VAZ, even a Tavria. One of the most economical offers is car lamps from the Karkam trademark, known to consumers for inexpensive and functional video recorders. Looking at the price of the kit, I can’t even believe that they have 6 original, according to the manufacturer, LED chips from the American company Cree. They are renowned for their excellent light output, slow crystal degradation and up to 30,000 hours of trouble-free operation.

The ability of the plinth to withstand difficult conditions is evidenced by the high degree of dust and moisture protection - IP68, and the massive aluminum heatsink and fan demonstrate resistance to overheating. The built-in reflector is designed to provide better light dispersion, and the number of lumens seems to be optimal: out of 4000 Lm, 1500 falls on the low beam and 2500 on the far beam, which is in full compliance with the standards. Unfortunately, this fact is unlikely to seem significant to traffic police officers - in 2018, as before, the operation of vehicles with lighting fixtures, the type of which does not correspond to factory parameters, is prohibited.

Sho-Mi lamps of the 7th generation of the Lite version (they use Epistar LEDs, not Philips ones) easily fit into the place of standard halogen lamps, so car owners do not need to contact the service or redo the installation place in any way . The difference can be seen with the naked eye immediately after installation: 16 20W LED chips provide pure white light with a color temperature of 5000K (similar to the midday sun). At the same time, the cut-off line remains quite clear, which is confirmed not only by visual assessment, but also by laboratory testing.

Braided copper bars are used as a radiator. During installation, the flexible parts straighten out, and the heating temperature of the LEDs is reduced to an acceptable level by increasing the surface area. Thus, effective natural cooling is ensured, and the lamps are able to operate at temperatures up to +80 °C. So that the on-board computer does not consider a decrease in power consumption as a failure, the manufacturer has provided built-in snags in the design. Just like external ones, they create an additional load in the power line, but neither the purchase of additional equipment nor its installation is required.

LED car lamps are an expensive pleasure and many car owners, having seen the average market price tag, decide to abandon LED lamps in favor of cheaper halogens. But there are quite budget products on the market, like the one that is now in front of us.Yes, the brand is Chinese, but let us remind you that even such eminent manufacturers such as Bosch most often produce goods in Asia, and not in Germany, where their headquarters are simply located.

Of course, this manufacturer has no reputation, but there are reviews left by real users. Judging by them, we have a confident middle peasant. It cannot be said that these are the best lamps, but you cannot call them frank rubbish either. The stated deadline is excellent. Forced cooling works, and the design allows you to direct the luminous flux exactly where you need it, and not under the bumper or into the sky. In general, quite an interesting option for your money.

The Narva brand has been engaged in automotive lighting for over 60 years and has earned a lot of accolades during this time. When he joined the Philips group, the degree of confidence grew even more, and the appearance of Range Power LEDs in Russia was met with extreme interest. The novelty provides increased visual comfort for the eyes during prolonged driving at night. The color of its luminous flux is characterized by a temperature of 6000 K, which is stable throughout the entire period of operation, and the correct arrangement of 6 diodes (3 on each side) gives a clear boundary of the illuminated area at a regulated distance of 50‒60 m.

The heat sink function in the design is performed by a flexible copper radiator. The stabilizer is placed outside, but the compact size and convenient connection of the input and output on one side allows you to embed the LED lamp into the headlight without changing the standard cover to a special one.In general, compactness is one of its most important advantages, thanks to which this ICE is compatible with most car models. But the declared service life is only 1500 hours, and one can only hope that the manufacturer was simply modest.

LED lamps will pass very controversial. On the one hand, LED crystals are reliable and capable of operating for decades without replacement and burnout. On the other hand, the slightest violation of the design leads to a very quick failure, and for such an expensive product, this is a critically important drawback. In order to somehow level this aspect, this Chinese manufacturer decided to give a guarantee. Moreover, this is a real guarantee, valid for a year from the date of purchase. If something happens to the lamps, you can easily replace them.

Reviews fully confirm this. Judging by them, the manufacturer is not trying to play up and dodge, shifting the blame on the user. He makes contact easily. Technical support provides assistance and advice, and if nothing helps, the product is simply replaced with a new one. An excellent approach for a relatively young brand trying to stay in a market where such mastodons as Bosch, Osram and Philips have long been operating.

Feedback from real buyers is one of the most important criteria when selecting products for the rating. There are a lot of them under this model, and the total user rating is close to 5. At the same time, the manufacturer cannot be called popular or attributed to the top segment.This is a Chinese brand, widely represented on Aliexpress and other Asian sites. But it is interesting that there is practically no bark here, like with other brands.

When buying these H4 bulbs, you can be sure of their quality, and it is at a fairly high level here. Also, the model is not afraid of vibration and, despite the absence of forced cooling, works great in extreme conditions. The design is thoughtful, and the LED crystals are covered with visors, and the flow direction allows you to put lamps in both low and high beam headlights. In general, if you are satisfied with the temperature of 5000K and the flow rate of 1150 lumens, be sure to pay attention to this model.

LED car lamps are not cheap. The price of some models can reach several tens of thousands of rubles, and not every car owner is ready for such expenses. On the other hand, the cheapest versions are also unlikely to have the best parameters, so you have to look for value for money. That was the main advantage of this model. This is a product of a top brand, one of the market leaders. Here, quality is closely monitored and reputation is valued.

Such light bulbs will last the prescribed period and will not fail at a crucial moment, while they have a quite adequate price tag. Yes, the product is not the cheapest, but given the quality and technical parameters, it is quite acceptable. Note that LED headlights work much longer than halogen or even xenon ones. Also, the advantages include a competent arrangement of diodes and design. The light is clear, directed where it is needed.

The cost of a pair of original Philips LEDs is high, but keep in mind that the cost of upgrading the standard lighting system is somehow justified due to greater durability. The manufacturer indicates that his offspring will serve at least 100 thousand hours (about 12 years), in practice, autolamps last longer. Do not discount the increase in driving safety - the main reason why they try to increase the brightness of the head light. Philips Z ES chips create a controlled beam of light for superior visibility.

Unlike Chinese companies, this manufacturer conscientiously indicates the real brightness of low and high beam LEDs: 1000 and 1250 Lm, which is about one and a half times higher than that of halogens. However, achieving bright light is half the battle, it is vital that it does not blind drivers of oncoming cars. Proper beam distribution is ensured by SafeBeam technology and high-precision production control. As a result, after installation in the headlights, the lamps retain the focus and geometry of halogen ones, draw a clear cut-off line (STG) at the right distance, perfectly illuminate the roadside and do not create problems on the road. That is why they are said to be completely suitable for replacing headlight bulbs in the optics of most cars.
