More light, better brightness at night. I'll see how the lifespan goes. Anyway, the company offers a 5-year warranty.

They were purchased at the beginning of December 2022 and lasted until the end of October 2022. As lamps, they provide quite good light, but unfortunately, coming from OSRAM CoolBlue Hyper H4, the comparison was like day and night. Additionally, they did not last long. I would suggest going for CoolBlue Hyper, but to each their own.

I admit that I expected a higher light intensity, they are just satisfactory. I would not buy them again, I would turn to LED.

They are quite good. In the Fiat Panda, compared to the factory ones, they are about 30% brighter on the medium scale. The +150% is definitely an extreme case or maybe for the large scale, where there is indeed a significant improvement. However, I expected them to be brighter. The color of the medium scale is about 3500K and the large scale is 4500K, which I would say is quite satisfactory in terms of road perception. Overall, I am satisfied.

The medium scale appears to be 3800k while the large one is 4500k. I don't know what the difference in color between the scales is beneficial for. I don't see the increased light output. Too conventional for €19, at least they should last longer than conventional ones.

Very good light compared to the factory. The only thing that concerns me is how long they will last. So far, one month and everything is fine. I don't give them 5 stars only because of their price.
