H4 Mi2 high and low beam headlamps kit | Ultra-flat CSP LEDs

Due to the high efficiency of CSP LEDs, we recommend the use of bulbs as dipped and / or high beam lights in lamps:

• reflectors
• lenticular

Minimized LEDs and excellent proportions of the dimensions of LED SLIM bulbs ensure almost exemplary light distribution, even in a lensless lamp! Correctly focusing the light beam is very important because:

• The light bulbs do not dazzle oncoming drivers while driving
• 100% of the bulb's power is transferred to the road in front of the vehicle, not to the shoulder, directly in front of the hood or above the road surface
• There is no need to readjust the low beam and / or high beam bulbs
• We do not have to worry about the vehicle inspection

Active cooling is to reduce the height of the air temperature with fan . The advantage of this solution is a much higher cooling capacity than in the case of passive cooling (without fan).

Bulb housing LED Mi2 is made of high-quality, highly thermally conductive aluminum ( Aviation aluminum 6063 )

H4 Mi2 LED bulbs are equipped with a rotatable bulb collar, as a result of which you can in adjust the angle of incidence of the light emitted by the diodes against the reflector. In addition, a removable collar facilitates the installation of bulbs in lamps that are difficult to access.

Efficiency of Mi2 bulbs:

When comparing the efficiency of the Mi2 LED bulbs and the standard bulb used in car headlights, we used the same lens settings, the same voltage (14V) and the same reflector lamp (Fiat Punto II, left side, without lens).

Above: bulb efficiency in theory (Ulbricht's ball).

Mi2 LED bulbs emit 400% more light than ordinary filament bulbs. The results are given in lumens (lm).

Above: The color of the light of the bulbs.

The Mi2 LED set emits light with a color of 6500k - snow white.

Above: verification of the cut-off line of the light / shadow.

The light bulbs emit light thanks to a minimalist design a very focused beam of light, unlike most LED bulbs on the market. The cut-off line is clear , the pillar of light precisely fills up area in front of the lamp below the eye line of the opposite drivers.

Above: bulb efficiency in practice.

In a practical test that takes into account the irregularity of the reflector of a car lamp, the Mi2 LED bulbs achieved a fantastic 1674 lux result. This means that the light beam emits almost 300% more light than the light beam of an ordinary filament bulb. The results are given in lux.

Summary of the test

The beam of light from LED Mi2 bulbs is characterized by an exemplary light cut-off, high luminance and a strong, white color of light even in a reflector lamp. The high intensity of the controlled light column makes it one of the most interesting items on the automotive LED lighting market.

Note: The performance test of LED bulbs is carried out by U.S on a bulb selected at random from the batch. All measuring devices, a traditional reflector lamp with a regulated 3-30V power supply and tested LED bulbs are available at our Warsaw Zmyślona point. We cordially invite everyone who would like to test the efficiency of the LED bulb on their own before buying.

The kit includes:

• Two H4 Mi2 CSP LED bulbs
• Pictorial assembly instructions
• Packaging (perfect for a gift)

Brief installation instructions for the LED bulb:

Step 1-2 : Unfasten the plate holding the bulb in the socket and remove the old bulb.

Step 3 : We remove the adapter from the 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 ankle. The light bulb power cord with the 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 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.
