Halogen G4 lamps: characteristics, pros and cons + rating of light bulb manufacturers

The main types of halogen lamps

Depending on the appearance and method of application, halogen lamps are divided into several main types:

• with an external flask;
• capsular;
• with reflector;
• linear.

With external flask

With a remote or external bulb, a halogen lamp is no different from standard Ilyich bulbs. They can be connected directly to a 220 volt network and have any shape and size. A distinctive feature is the presence in a standard glass bulb of a small halogen bulb with a bulb made of heat-resistant quartz. Halogen lamps with a remote bulb are used in various lamps, chandeliers and other lighting devices with an E27 or E14 base.

Capsule

Capsular halogen lamps are miniature in size and are used to organize interior lighting. They have low power and are often used with sockets G4, G5 in a 12 - 24 volt DC network and G9 in a 220 volt AC network.

Structurally, such a lamp has a filament body located in a longitudinal or transverse plane, and a reflective substance is applied on the rear wall of the bulb. Such devices, due to their low power and size, do not require a special protective bulb and can be mounted in open-type luminaires.

With reflector

Reflector devices are designed to emit light in a directed manner. Halogen lamps may have an aluminum or interference reflector. The most common of these two options is aluminum. It redistributes and focuses the heat flux and light radiation forward, due to which the light flux is directed to the desired point, and excess heat is removed, protecting the space and materials around the lamp from overheating.

The interference reflector conducts heat inside the lamp. Halogen reflector lamps come in a variety of shapes and sizes, as well as different light emission angles.

Linear

The oldest type of halogen lamp, which has been used since the mid-60s of the 20th century. Linear halogen lamps look like an elongated tube, at the ends of which there are contacts. Linear lamps come in various sizes as well as high wattage, and are mainly applied to various spotlights and street lighting fixtures.

Halogen lamps with IRC coating

IRC-halogen lamps are a special kind of this kind of lighting devices. IRC stands for "infrared coverage". They have a special coating on the flask that freely transmits visible light, but prevents the passage of infrared radiation. The composition of the coating directs this radiation back to the filament, which increases the efficiency and efficiency of the halogen lamp, improves the uniformity of the glow and light output.

The use of IRC technology makes it possible to reduce the consumption of electrical energy by such devices by up to 50% and significantly affects the energy efficiency of the lighting device. Another advantage is the increase in service life by almost 2 times, in comparison with standard halogen lamps.

Halogen chandeliers

Halogen chandeliers are one-piece devices that are based on many halogen lamps connected in parallel to each other. Such chandeliers have a completely different appearance and configuration, and due to the small size of halogen lamps, they have an aesthetic appearance and a uniform glow.

In stores, you can find halogen chandeliers powered by 220 volts AC, as well as low-voltage options for use in DC systems or using with power supplies.

Varieties of halogen bulbs

Bulbs with halogens are classified according to power sources:

• low voltage version with 12 volt driver;
• incandescent lamps 220v.

The classification of lamps is shown in the figure below.

Low-voltage light bulbs can also be connected to a dedicated 220V power supply, but only with a step-down transformer. This device reduces the voltage to an acceptable level (12 volts). Halogen bulbs of this type have a pin base G4, G9, GU10, G12. Also in the automotive industry, a base type H4 is used.

The types of plinths are shown in the following figure.

Light bulbs are usually divided into several types depending on the features of their design:

• linear;
• capsular;
• with reflector;
• with a remote flask;
• low voltage;
• halogen chandeliers;
• IRC halogen light sources.

Linear

With this type of light bulbs, the production of halogen light sources began. Such lamps are produced to this day. The design of linear light sources has a pair of pin holders on both sides of the elongated bulb. For domestic purposes, such devices are rarely used because of their high power (from 1 to 20 kW).

Capsule

Such light bulbs are characterized by their small dimensions. Capsular light sources are used to illuminate interiors. G4 and G9 bases are usually used. As for the G9, this base is designed for a 220 V network. Due to their compactness and low power, capsule devices are often installed in open-type luminaires.

With reflector

Halogen lamps with reflectors are also referred to as directional lamps. A similar effect is achieved through the use of a reflector, which is performed in one of two options - interference or aluminum.In the case of an aluminum reflector, heat is dissipated to the front, while the interference design involves heat dissipation to the rear. Also, devices with a reflector are made with a protective cover and without it. Lamps with a reflector are equipped with different types of socles: for a 220 V network or low-voltage - for 12 Volts.

With extended flask

External bulb devices are often confused with standard incandescent bulbs. They have a similar design, including an E14 or E27 threaded base, the same glass bulb and filament. But there are halogens inside a bulb with a remote bulb.

Halogen chandeliers

Light sources of this type are produced with an E17 or E27 base. One of the main characteristics of chandeliers is the small size of the bulbs, they are almost invisible. Chandeliers are usually designed to operate from a 220 V network, however, there are also low-voltage lamps. In the latter case, you will need to connect through a step-down transformer.

Note! To avoid overheating, it is recommended to use ceramic cartridges instead of standard cartridges.

Low voltage

Low-voltage light sources include devices powered by 6, 12 or 24 volts. The most common option is a 12 volt lamp. Most often, low-voltage halogen bulbs are used when installed on flammable bases. They are used to illuminate interiors (spot lighting), small fragments of garden plots, to illuminate exhibits in museums, etc.

Due to their safety, low-voltage light sources are approved for use in rooms with a high level of humidity. But in this case, it is necessary to ensure reliable protection of the base from water ingress on it.

Note! Low voltage devices are always connected to the mains through transformers.

IRC halogen lamps

Halogen IRC lamps have a special coating that is transparent to visible light, but is a barrier to infrared radiation. This coating receives infrared light and reflects it back to the helix. This technology reduces heat loss and increases lamp efficiency. According to Orasm, the leading manufacturer, the technology reduces electricity consumption by 45% compared to other halogen bulbs. At the same time, the service life of the device is increased by 2 times. The IRC lamp allows you to get a powerful luminous flux - 1700 lm, as well as a light output of 26 lm / W, which is twice as high as a possible 35-watt fluorescent light source.

Overview of types and characteristics

According to the type of power source two groups of lamps: low-voltage (12V) and analogues for direct connection to the 220V network. The difference between them is where the driver / power supply is located: inside the structure or is it a separate node. Such light bulbs also differ in power. Load value range: from 0.4 to 7.8 W. Moreover, executions with fractional (1.5W; 1.2W) and integer values ​​(2W; 3W; 5W) are equally popular.

Another factor on the basis of which the difference between G4 lamps is made is the shape of the bulb. So, open light sources, analogs with a flask of various shapes and flattened bulbs in the form of a disk (tablet) are common. The number of diodes can vary as well as their type.

SMD diodes, characterized by compactness, high brightness factor, power and wide radiation pattern.

SMD LEDs are more commonly used, their sizes are encrypted in the designation: 3528, 2835, 5050, 5630, etc. The larger the dimensions of the light source, the brighter the light it will provide.

Main technical characteristics of light bulbs with G4 holder:

Color temperature table

To make it easier to understand what kind of light the G4 lamp provides, it is often indicated that it belongs to warm or cold shades.

Which H4 halogen bulb is better to buy

Among the named nominees, each described H4 bulb has its own characteristics, strengths and weaknesses. This can make it difficult for the buyer to choose the right solution. It is worth relying on individual needs, budget, conditions of one's own comfort on the road. Based on the rating, several conclusions can be drawn:

• The brightest white light is Mtf-Light Argentum + 80% H4;
• The longest service life - Philips H4 LongLife EcoVision;
• The best ratio of quality and price - Osram Original Line H4;
• The best offer for bad weather is General Electric Extra Life;
• The lowest price is Narva H4 Standard.

For constant driving in the city, devices from the category with an extended service life are perfect

For the track, it is especially important to find that "halogen" that demonstrates a good near, long-range mode

If the driver has vision problems, you should pay attention to the category with improved visual comfort or increased brightness. LED devices are the undoubted leaders, but not everyone can afford such waste.

How G4 products work

Inside the G4 halogen is a tungsten coil. When the device is connected to the mains, the current passes through the contacts, enters the incandescent element and heats it up to a high temperature. At this moment, a glow is formed in the lamp.

The high operating temperature forces the tungsten atoms to evaporate from the coil. The halogen vapors in the flask and surrounding the filament combine with tungsten atoms and prevent their condensation on the colder inner surfaces of the flask.

G4 halogen modules demonstrate the same high-quality performance on both direct and alternating current. When used in the soft start mode, they last much longer than the manufacturer claims, in some cases up to 8000-12000 hours

The whole process is reversible and is a kind of cycle. The working compound decomposes into its constituent substances in the immediate vicinity of the incandescent spiral due to high temperature and the tungsten atoms again return to the same place where they were.

This makes it possible to significantly increase the operating temperature of the spiral part and obtain a much brighter, more saturated and uniform light flux.

Contacting only with a spiral element, tungsten atoms do not have a negative effect on the internal surfaces of the bulb itself, and the service life of the light source is significantly increased.

The same moment helps to reduce the size of the light bulb, while maintaining its full power.

Osram 64193CBI-HCB

Osram 64193CBI-HCB are Cool Blue Intense halogen lamps that produce bright light with a color temperature of 4200 Kelvin. The light of such a lamp is as close as possible to natural daylight, which makes it pleasant to the eyes and does not cause fatigue, unlike standard lamps. Compared to standard OSRAM halogen lamps, COOL BLUE INTENSE is up to 20% brighter. The road and the roadside are illuminated far and brightly, even in cloudy weather.In addition, these lamps have a fairly long life compared to conventional halogen lamps. In general, a great option for your money. But before buying such lamps, please note that the name of the Cool Blue Intense line is nothing more than a marketing ploy. The manufacturer claims that the lamps of this line create a bright white-blue light, reminiscent of the illumination of xenon headlights. In fact, as buyers note, a white-yellow light is obtained, characteristic of halogen lamps. So, if you are looking for lamps that create the effect of xenon illumination, this option is not for you.

The best H4 halogen bulbs for cars

This section presents the simplest halogen lamps. With these bulbs, manufacturers didn't go after improved sharpness, longer life, or better color temperatures, so they managed to keep the cost fairly low.

In addition, typical power, sharpness and durability factors make these models the most versatile for any environment. According to their own technology, halogen lamps are next to ordinary light bulbs. The vessel has the same thread. The difference is that here, instead of empty space, the vacuum is filled with passive gases with Br or Cl.

In addition, it should be noted that in the H4 models there are 2 filaments at the same time. One of them is responsible for the near, and the second - for the main beam. Moreover, the characteristics of the glow and its temperature can be completely different. Below is the TOP of the best in this category.

2nd place: OSRAM ORIGINAL LINE H4

The disadvantage is the resource, which is significantly inferior to even inexpensive analogues. For a set of two pieces, the driver will have to pay 1,100 rudders.

Popular manufacturers of lamps with H1 base

There are not so many manufacturers of lamps with an H1 base on the modern market. All of them either reprofiled and began to produce autolamps with a different base, or completely ceased their activities. But the requirements for them are still at the highest level, and current manufacturers easily manage to support it.

Popular manufacturers today include:

• CLEARLIGHT;
• XENITE;
• SHO-ME;
• Bosch;
• OSRAM;
• PHILIPS;
• AVTOVINS.

But still, when choosing a car lamp, it is better to pay attention not to the manufacturer, but to a specific model and its characteristics. Only in this way you can choose the perfect option for yourself and not pay a large amount of money for it.

Best H4 LED Bulb for Car

Models of the LED type began to be used recently, but quickly won the hearts of drivers. This is due to their increased durability, high quality lighting and budget cost.

Classification of modules with G4 base

This type of halogen is available in two versions: in the form of a small capsule or in the form of a truncated cone with a reflector. Each of the designs is designed for specific purposes and correctly provides the required light output in suitable conditions.

Features of capsule devices

Halogens G4, having an elongated elongated flask made of quartz glass, are called capsular or finger. The incandescent spiral in them is located longitudinally or transversely and, as a rule, in one layer.

The rear wall of the interior space is covered with a special reflective compound. The modules do not need additional external reflectors and protective elements.

The small dimensions of the flask allow you to create a higher pressure inside. This reduces the rate of evaporation of tungsten atoms and increases the working life of the light bulb.

The compactness of the products allows them to be used to illuminate furniture sets, ceiling space, shop windows and retail facilities. In everyday life, decorative sconces, chandeliers and lamps of the most unexpected shapes and configurations are completed with small light sources.

Being low-voltage light sources, for a correct connection to the 220 W network, they need a transformer that lowers the base voltage.

Capsule-type devices mainly have a warm range of working light flux. However, compared to classic incandescent lamps, their tonality spectrum is much closer to the natural white glow that is characteristic of the natural environment.

G4 halogens, even at low power, have good brightness and almost without distortion convey the complexion of people in the room, and interior elements and pieces of furniture are illuminated with a pleasant neutral-warm light.

Halogen models with a g4 base perform well in devices designed to create accent lighting in a room, demonstrate a high level of color output and last twice as long as classic Ilyich bulbs

On illuminated surfaces, capsule devices create an attractive glossy effect, while maintaining the natural tonality inherent in objects.

This lighting option allows you to convey the overall color orientation of the interior, emphasizing its most catchy and original elements.

Distinctive features of models with a reflector

G4 halogen devices with a reflector have a specific shape resembling a truncated cone and are called reflex devices. They give a directional light stream at different angles.

Inside the flask of such devices is a special element that reflects light and distributes it more clearly and evenly.

The reflector is usually of two types:

• interference;
• aluminum.

The first type has a translucent texture and actively removes the generated heat back, which significantly enhances the basic light intensity, but makes its flow diffuse and wide.

The second option redirects the resulting heat forward and creates a narrower, brighter and more concentrated beam of light.

There are also some differences in the design of the bulbs. Different manufacturers produce modules with a G4 base, both with and without a protective glass cover. The configuration of products is determined by the intended purpose.

Halogen lamps with reflectors can be safely used in children's rooms. With this type of lighting, the child will be able to read, draw or do any other business for a long time without straining his eyes and without feeling any fatigue.

The angle of dispersion of G4 halogen reflective bulbs ranges from 8 to 60 degrees. This quality allows you to mount light sources with reflectors in devices that provide directional illumination of goods and exhibits.

Modules with external protection against damage are suitable for use in open luminaires of any configuration. Halogens without a cover are mounted only in closed fixtures, where there is no direct access to the surface of the bulb.

Halogen lamps

The popularity of artificial light sources based on halogens is explained by the reluctance of consumers to experiment with new, more expensive technologies. Such people continue to "move along the trodden path", replacing a burned-out halogen lamp with the same product. This continues until a good friend in practice proves the superiority of LED light sources.

How does it work?

The device of halogen lamps largely repeats the design of conventional incandescent lamps. The difference lies in the presence of halogen (iodine or bromine) inside the bulb, which extends the life of the lighting device by 2–4 times.

When turned on, the filament gets very hot and starts to glow. The whole process is accompanied by active evaporation of tungsten from the surface of the spiral. The released tungsten atoms react with iodine (bromine), which prevents their deposition on the inner surface of the flask. The action of the gas is aimed at returning metal particles to the body of heat.

As a result, a kind of positive feedback is created around the luminous thread. This effect contributes to an increase in the temperature of the spiral up to 3 thousand Kelvin, which, in turn, increases the brightness of the glow. The shape of halogen lamps can vary greatly. Their large assortment is explained by their specialized application (car headlights, searchlights, medical equipment).

One of the latest achievements of scientists is HIR (Halogen Infrared Reflecting) technology. In this type of halogen lamps, infrared radiation does not leave the bulb. A protective coating applied to the inside of the glass returns the thermal component of the light flux back to the spiral. Reflected heat heats it up and leads to an increase in light output.

The design of the HIR lamp has an elongated glass bulb with a spherical shape around the spiral. Devices with an infrared reflector stand out with an increased color temperature and give off 70% more luminous flux than their conventional counterparts.

pros

Halogen lamps have several advantages:

• require a minimum of effort when replacing conventional incandescent lamps;
• emit warm tones reminiscent of sunlight;
• have a market value acceptable to most buyers.

Due to the low cost, the production and consumption of halogen lamps remains at a high level. Due to their compactness and resistance to voltage drops, they are actively used in car headlights.

Minuses

Most of the energy consumed is spent on maintaining the glow, and the efficiency of halogen lamps does not exceed the threshold of 15%. The working resource, on average, is 2000 hours, depending on the frequency of switching on the lamp and jumps in the network.To increase the life of halogen bulbs, some consumers are forced to install dimmer switches in the house to ensure a soft start.

Which H1 bulbs are better to choose?

We take into account that lamps with an H1 base are still the lot of used cars, which means that the optics will no longer be in the best condition: a dull reflector, a cloudy diffuser. In this case, of course, the most interesting purchase option is lamps with increased light output, and primarily for head optics. There is a nuance in fog lights - they are doused with cold water more often, and “reinforced” lamps are usually hotter than standard ones. This means that the risk of cracking the diffuser is higher. When buying lamps with increased brightness, you need to be more careful about their light distribution - if they start to "high" into the oncoming lane, it will be much more noticeable to drivers there.

It is difficult to assess how specific lamps will behave in specific headlights in a store, but at least the packaging must clearly indicate the compliance of the lamps with the European ECE standard. It is European, and not American or, even more so, Japanese. Lack of certification instructions is a reason to be wary. It is normal practice among manufacturers "with a name" to directly indicate on the packaging that the lamps are intended exclusively for use off-road use (for off-road use only): for example, such lamps can be put in a search headlight or "chandelier" headlights of a raid car , but on the road they really have nothing to do.Korean and Japanese manufacturers sometimes write the bare minimum in languages ​​understandable to a white person - it’s better to look for their tests before buying to more or less make sure that such bulbs in the headlights work correctly.

As for the color temperature, then, of course, you can choose any, except that white, leaving in a bright blue - a thing for a masochist (and does not really illuminate, and tires the eyes quickly). However, a rich yellow glow is still better left for fog lights with transparent diffusers, making the main light whiter: each color has its own advantages, and in this combination they will reveal themselves best.

Colorful temperature

Color temperature using xenon as an example

Many consider xenon lamps to be the standard of good lighting, which they have never had. Usually any neutral white light source at 4300K, 5000K, 6000K they call xenon. In reality, a light source of 2800-3200 lumens can be called similar to xenon.

At night, the sensitivity of the eye to white light at 5000K - 6000K increases by 50% -80%. This figure depends on your age and condition of vision. You encounter a change in the sensitivity of the eye when you enter a dark room. After a while, the eye adapts and you begin to distinguish objects.

To make halogens and xenon related, the color temperature is indicated as "Xenon Effect" (Xenon Effect), and not "neutral white light". Yes, and it boasts more conveniently, like I have halogen bulbs with xenon.

Philips lineup, photo

To obtain a white color at 5000K from a halogen lamp with a color temperature of 3100K, blue sputtering is used. The sputtering works as a light filter, delaying yellow in the radiation spectrum, while Lumens are reduced.For example, for the H11 base, the luminous flux is usually 1500 lumens, with spraying it turns out about 1000lm. The losses are quite significant, but multiplying 1000lm by a factor of 65% (average between 50% and 80%) for white, we get 1650lm.

It turns out with a neutral white coating, it will illuminate like 1650lm of ordinary, warm 3100K. The difference is only 150lm, but due to white it seems that it illuminates much better. Our eyes prefer neutral daylight, with such lighting it is more habitual to distinguish objects. As you can see, a 1000lm 4300K ​​autolamp is very far from xenon at 2800lm 4300K, the difference is almost 300%.

Another way to obtain the xenon effect is to reheat the halogen source coil. The load on the spiral increases significantly, the resource is reduced to 150 hours, and often fail.

The quality of branded Philips and Osram is stable, they are checked according to European quality control requirements. For Chinese brands Clearlight, Shoe-me, the blue coating falls off after 2 months, for some, the flask cracks and dies in 1-2 months. It is difficult for an ordinary person to imagine that it is possible to somehow save money on a halogen lamp consisting of a bulb and a thread.

Which company is better to choose for a car lamp H4

H4 lamps are a fairly popular product, and therefore you can see many companies that manufacture them. However, not everyone will give the quality that they expect.

And which companies are better to choose? We offer five of these for consideration, which will give what all car owners desire, in the table below.
