In this manual, we have listed all the most important characteristics that are used when choosing H4 LED Bulbs: the power of the H4 LED Bulbs emitter (W), Luminous flux of H4 LED Bulbs (Lumens), and color temperature of H4 LED Bulbs (Kelvin).
The H4 bulb is a traditional headlight option that has long been in constant demand in the motorist market. They are often installed in four-phase systems for headlights. Initially, h4 bulbs were installed only for dipped beams, sometimes for high beams. H4 LED bulb, the bulb is made of quartz refractory glass. H4 LED bulb is filled with an inert gas compounded with halogen vapor. They have a higher light output than incandescent bulbs.

How to choose H4 LED Bulbs?
When choosing H4 LED Bulbs for the car, you need to consider the type and socket of the lamp, bulbs power, bulbs temperature, manufacturer brand, and lamp life.
An important parameter when choosing H4 LED Bulbs is the light emitted by the bulb.
How bright and high quality the H4 LED Bulbs will depend on several factors:
- Power of the H4 Halogen Bulbs emitter
- Luminous flux of H4 Halogen Bulbs
- Color temperature of H4 Halogen Bulbs
- H4 Halogen Bulbs light directionality
Power of the H4 LED Bulbs
The power rating of the H4 LED Bulbs is measured in watts (W) and is specified in the bulb datasheet.
Luminous flux of H4 LED Bulbs
The luminous flux of H4 LED Bulbs is the brightness of the beam emitted by the source. The brightness of the light beam is usually measured in lumens.
The 5000-6000 lumens (low intensity) lamps illuminate the road more than 500 meters in a straight line and are suitable for most drivers. At 8000 lumens (medium intensity) the road is illuminated for 600-700 meters in a straight line. Lamps with 10 000 – 12 000 lumens (high intensity) illuminate the road almost as well as daylight.
H4 Bulbs Color Temperature
The color temperature of an H4 LED bulb is one of the most important characteristics that indicate the color emission of an automotive bulb. The luminous flux temperature is used to determine which color the lamp will glow.
The objective impression of the color of the H4 LED bulb is determined by the color temperature measured in Kelvin. The table of colors and temperatures of H4 lamps come in different colors from yellow (3000K – 4300K), white (5000K – 6000K), to blue and magenta (8000K and more).
The color temperature of H4 LED lamps is about 2,800K, this warm-yellowish light is most familiar to the eye (2700 to 3500K). Halogen lights used in fog lights or headlights are in the 3000K range. HID lights start at 3000K and can reach up to 10,000K. Newer LED lights can have a luminous flux of up to 12,000K.
| Color | Color Temperature | Description |
| Yellow | 3000 K | Pure natural yellow light |
| White | 4300 K | Yellowish white light (dim white light) |
| Pure White | 5000 K | Pure white light (imitates natural light) |
| Crystal White | 6000 K | Pure white light with a small amount of blue |
| Light Blue | 8000 K | Bluish-white light with a higher percentage of blue |
| Blue | 10 000 K | Dark blue light bordering on violet. |
| Violet | 12 000 K | Dark purple saturated light |
Directionality of H4 LED Bulbs
The need to adjust the H4 LED Bulbs most often arises during the replacement of the lamp or during the long-term operation of the vehicle.
Due to driving on rough roads and constant vibration the geometry of the car headlights is disturbed. This leads to misdirection of the light flux and the risk of creating an accident on the road. Therefore, after the purchase of H4 LED Bulbs, it is necessary to adjust the lamp. H4 LED Bulbs are adjusted in height and direction, separately for each headlight.
If a headlight bulb burns out, should you replace two bulbs or one?
If you only replace the burned-out H4 LED Bulbs, the second bulb will eventually fail as well. Over time, the brightness of the H4 LED Bulbs drops, and the color temperature increases. Therefore, H4 LED Bulbs should only be replaced in pairs. Otherwise, driving will be uncomfortable because the new bulb will shine brighter than the old one.
H4 LED Bulbs Buying Guide
When buying H4 LED Bulbs, you need to pay attention to the cost of the lamp, the manufacturer, as well as the life of the H4 LED Bulb.
H4 LED Bulbs Manufacturers
We recommend that you do not save money when buying H4 LED Bulbs and choose proven brands that have proven themselves in the work. The best brands of H4 bulbs for cars according to our editorial board are: Sylvania, Osram, Philips, Optilux Hella, Bosch.
Cost of H4 LED Bulbs
- Up to 20 dollars: for this price you can buy good H4 LED Bulbs of little-known manufacturer
- Up to $50: For this price you can buy good H4 LED Bulbs from a well-known manufacturer
