LED H4 F6 DOB low beam or high beam kit | Driver-On-Board LEDs

Over 55% more light than ordinary light bulbs!

Due to the very high luminous efficiency of the set, the bulbs can be used as a replacement for lights:

• passing
• road

Advantages of LED DOB technology as the main car lighting:

• Extremely long service life
• Increased light efficiency
• Small dimensions of the bulb

DOB (Driver On Board) it is a technology for powering a direct light module with LED diodes, in which the power supply system and the LED light source are located on one board, without the use of an additional power supply. The main reasons for the growing popularity of such a solution are increased service life and better luminous efficiency. In addition, the dimensions of the bulb are smaller than that of other LED bulbs for use in the main lighting of a car.

Main features of LED DOB technology:

• Compact design
• More efficient cooling
• More efficient use of elements responsible for luminous efficiency
• Overvoltage protections
• Thermal protections

As much as 56% more light than standard bulbs!

Technical Specifications:

• Model: LED dipped beam H4 F6 DOB
• Number of LED bulbs: 2
• Number of LEDs: 4 / bulb
• LED technology: DOB - Driver On Board
• Total current consumption: 50W
• Splash Resistant: IP67
• Supply voltage: 12V

The bulbs have built-in CAN-BUS filters, so they cause errors on the on-board computer.

H4 F6 DOB LED bulbs are equipped with a removable collar for easy installation light bulbs in lamps that are difficult to access. In addition, thanks to the ability to rotate the adapter 360 ° relative to the axis of the bulb, you can fully adjust the angle of incidence of light emitted by the diodes against the reflector.

Thanks to their small dimensions, LED H4 F6 DOB bulbs are compatible with almost every car lamp.

The use of DOB diodes allowed to reduce the total height of the bulb up to 70 mm , and the heat sink itself up to 20 mm . Few of the bulbs for sale can be as compact as the H4 F6.

Efficiency of LED H4 F6 DOB bulbs:

H4 F6 DOB LED bulbs emit more than 55% more light compared to ordinary bulbs. When comparing the efficiency of H4 bulbs used in car headlights, we used the same lens settings , same voltage 14V and the same reflector lamp (Fiat Punto II, left side, without lens).

The beam of light from LED H4 F6 DOB bulbs is characterized by a good light cut-off, high luminance and a strong, white color of light even in a reflector lamp.

The kit includes:

• Two H4 F6 LED bulbs with DOB diodes
• Packaging (perfect for a gift)

Quick installation guide for H4 LED bulb with detachable adapter / collar:

Step 3 : Remove the adapter from the H4 LED bulb. We put it in the place of the bulb, and then fasten the mounting plate.

Step 4 : Insert the bulb into the previously fastened adapter. We connect the bulb to the H4 cube. The light bulb power cord with the H4 cube is best placed inside the lamp, between the housing and the reflector. The bulb can be rotated 360 ° in order to find the appropriate angle of incidence of light on the illuminated area in front of the vehicle.

Step 5 : Put a cover on the housing to protect the inside of the lamp against moisture.

Despite the small amount of space in the tested lamp (Fiat Punto II), after installing the H4 LED, it was possible to close the cover and seal the inside of the lamp. Before buying, we recommend that you check whether the target lamp has a spare space between the bulb's collar and the cover. In our lamp, the distance between the bulb and the edge of the housing on which the cover is inserted is 32 mm.
