Types of D4S bulbs

  1. Halogen Bulbs
  2. LED Bulbs
  3. Xenon Bulbs

D4S Halogen Bulbs

The halogen D4S bulb is arranged as follows: the filament is located in a bulb, the material of which is carbide or quartz glass.

Halogen D4S bulbs are easy to install, inexpensive, and good performance. Along with these advantages, halogen lamps have a disadvantage. During operation, they heat up to a high temperature.

Halogen D4S bulbs have a good price to quality ratio, which is the reason for their frequent use. Currently, among the manufacturers of D4S bulbs, there are several leaders in terms of brightness. These brands are OSRAM, Philips, SYLVANIA, the brightness of these lamps is 150% higher than the standard lamp.

Halogen D4S bulbs are fully approved for on-road use in all states and are warranted by the manufacturer. We have chosen incandescent bulbs with 150% more light, these D4S halogen bulbs are the brightest on the market.

These bulbs are easy to install because you replace halogen with halogen, and you have no problem installing them. The disadvantage of D4S halogen bulbs is their lifespan.

The brighter the light, the shorter the life of the D4S bulb. This is because there is a filament inside the D4S bulb, which burns out quickly. If you want a long life, use LED bulbs.

Best D4S LED Bulbs

LED D4S bulbs are usually brighter than halogen bulbs. They last much longer, use less energy, and are easy to install.

The D4S LED lights are often the perfect choice for those looking for clean, bright, white light. Today, they are considered one of the best. This fact is due to their following advantages:

  • Low power consumption
  • Large operating term
  • Resistance to mechanical vibrations

The lighting device based on diodes is suitable for both low and high beams. In addition to the positives, LED D4S bulbs have a disadvantage – the high cost. LED lamps from halogen lamps differ in that the latter are spotlight sources. LED bulbs consist of a cylinder on which LEDs are installed. The most popular D4S LED bulb manufacturers: OSRAM, Philips, BEAMTECH, HIKARI, Fahren, Cougar Motor, NINEO, Aukee, AUTO ONE, CAR ROVER, and others.

Best D4S Xenon Bulbs

The xenon D4S lamp consists of a bulb containing gases and two electrodes. The D4S headlight shines due to the electric arc that occurs between the electrodes.

Genuine D4S Xenon headlights are standard on some vehicles but are often offered as an option when you purchase your car. Xenon D4S headlights work a little differently than standard halogen bulbs, and actually require two main components to work: ballast and bulb. Compared to other car bulbs, xenon bulbs have the following features:

  • white color with a tinge of blue, which does not blind oncoming drivers
  • high luminous intensity
  • immunity to mechanical vibration

Xenon auto lamp D4S is not without disadvantages, namely:

  1. High price
  2. When installing it is required to additionally install the ignition unit (ballast)

The disadvantages are the reason why the xenon bulb is used less often than the halogen bulb. The most popular LED bulb manufacturers: OSRAM, Philips, SYLVANIA, Optilux Hella, Xentec, RCP, and others.

D4S Bulbs Review

A review of D4S bulbs can boil down to a few parameters

It is the type of D4S bulb: halogen bulbs, LED bulbs, or xenon lamps. The next factors are the brightness of the bulbs and the color of the lamps.

Lamps with a D4S base are used for cars with high mileage, which means that the optics will not be in the best condition: faded reflector, cloudy diffuser. In this case, the most interesting option for purchase is lamps with increased luminous efficacy. Careful when buying bulbs with increased brightness and need to be to their light distribution – if they will start to blow on the oncoming lane, the drivers there will be much more noticeable.

The normal practice among well-known manufacturers to indicate on the packaging that the lamps are designed exclusively for off-road use only (for off-road use): For example, such lamps can be put in the headlight-seeker or headlamp chandelier raid car, but on the road, they really have nothing to do.

As for the color temperature, of course, you can choose any, except that white, going into a bright blue. However, the saturated yellow glow is still better left for the fog lights with transparent diffusers, the main light to make whiter: each color has its own advantages, and here in this combination they are best revealed.

Make sure you buy the right type of bulb for your car. D4S bulbs are bulbs for a car headlight or for fog light. You can determine what type of bulb you need for your car by checking this information in your owner’s manual. You can also find out what type of bulb you need by using the bulb selection by make and model of your car using our website. On the car bulb finder page, you will find information on what type of bulbs you need to use.

D4S Bulbs Buying Guide

Once you’ve determined that D4S bulbs are what you need, you can start searching for the brightest D4S bulbs. When choosing a D4S bulb, you need to consider the following factors:

  • Light distribution on the road
  • Power consumption
  • Luminous flux
  • Compliance with light distribution with established standards

Power of D4S bulbs diode

The power of the LED depends on the brightness of the light it emits, and the higher the quality of the diode, the higher its efficiency will be. We do not recommend that you choose the most powerful and brightest models for your vehicle.

Dependence of power from the cooling system D4S bulbs

An LED generates a lot of heat when it emits light, and the higher the wattage of the lamp, the more heat the lamp produces. Poor cooling or poor quality results in the LED not being able to operate at full power.

The noisiness of the D4S bulbs cooler

If your choice fell on a powerful D4S lamp with active cooling, then note that the cooler’s poor quality lamps are not only more likely to fail but also create a certain noise and vibration, which can be heard in the cabin. Constant monotonous barely audible hum sooner or later will drive even the most sedate driver crazy.

The brightness of D4S bulbs

It is customary to measure the brightness of a lamp in lumens, this value indicates how much light you get from the lamp. Lumens indicate the amount of light distributed by any light source. The more lumens, the brighter the light from the lamp. At the same time, fewer lumens give less light.

Bulb Light

Color temperature D4S bulbs

The most popular D4S LED bulbs have a color temperature of 5000-6000K, such a bulb is suitable for most cars. If you prefer the yellow color of the headlights, it is better to choose a D4S lamp with a temperature of 4000K, such a lamp will be less bright, but more natural for the eyes. Brighter light sources with a temperature of 5000-6000K provide better visibility in rainy weather when the lamp is properly focused than similar light sources with a yellow spectrum. Do not raise the color temperature of the lamp too much and choose D4S bulbs with 7000-8000 K, regardless of optics and focus, they will not provide the same quality illumination. Modern D4S LED lamps are capable of producing light with different color temperatures:

  1. Warm white (up to 3500 K)
  2. Neutral white (4200 to 5000 K)
  3. Cold white (temperature 6000 to 10000 K)

How do I install a D4S bulb?

To facilitate installation in cramped conditions, the ring of the base on all the bulbs is made removable. First, the ring of the base is installed, clamped by a locking device, then the D4S diode bulb itself is placed. Sometimes there are problems when installing the light bulb in the headlight, the headlight cover does not close when the cooling system is placed.

Always remember that the choice of automobile lamps D4S for dipped beam – a responsible thing, because they determine the safety of the road.
