Finally, after failed purchases of €10 and €15, I spent a bit more and got these. The previous ones were Chinese, just like these, but in this case, the light is really powerful and white. Stronger than halogen lamps. They were installed on a VFR1200F motorcycle.

Time will tell for durability. The intensity of the light is clearly better than halogen now if it achieves the nominal performance it claims, I don't know, I am satisfied especially for the size, you don't do any tricks on the flashlight.

They provide sufficient lighting, I would say double than halogen and not 3-4 times more as the company claims. If they bother others and how long they will last, I do not know yet because it has been one day since I installed them. So for now, 5 stars and if I see any unreliability, I will come back to lower the stars.

Better lighting compared to halogen in Hyundai I30, but be careful with the installation if you do it yourself, they should be placed vertically, meaning the LEDs should be facing right and left, as they can also be installed horizontally, but in this case they will not shine properly.
As for durability, I will come back if necessary. They do have a 2-year warranty.

Let's start with something basic... it is advertised that they have a brightness of 12,000 lumens. For reference, equivalent halogen bulbs have 1,100-1,200 lumens... so one would expect that as soon as they are installed, they would see the true light, something that unfortunately was not confirmed. Also, it should be mentioned that the cooling fans they have (even though the bulb is enclosed inside the lantern) can be heard in quiet conditions. In summary, the only benefit I see is the 6,500K and the fact that they generate much lower temperatures compared to halogen and xenon bulbs.
