I decided to buy the whole series of H1, H7, and H11 to make my car's lights a little cooler. In the H1, one of the two bulbs burned out after 1.5 years. Other than that, they are Halogen bulbs with a slightly cooler light. Nice, but not great.

I wanted pure white light at 4300k and this achieves it 100%. As for brightness, it's fine, I didn't expect miracles from a halogen bulb. I chose them for both a large scale and for the spotlights. It remains to be seen how durable they are.

I had bought them again about 10+ years ago with excellent results on Astra H OPC headlights for the high beam. Wonderful white light and intensity.
Now the absolute disappointment on Maxsym 400 Scooter headlights. No intensity at all and it doesn't have the whiteness of the past. Truly disappointing.

Philips is a reliable brand. Used in a ford focus mk1 on a large scale, the difference from the stock lights is tremendous. For years, I have been using the same model, H4, in my previous car and I have always been satisfied with the color and durability. The color is soothing and clean. I recommend the crystal vision to anyone who wants white light and does not want to install xenon or LED lights.

Mazda6 2006 projectors in the middle range installation.. You see white light but when you turn, the side light doesn't cover you and it's dark.. On straight roads, it's okay but at a close distance, around 10-12 meters, it's average.. What they say about long distance and so on, I believe it's not true unless it works on reflectors.. On 26/03/2022, I took it out to try a Led.. It burned strangely.. I put a simple one, the caetech uv vision.. Honestly, there is no difference!!! I was incredibly surprised.. I thought it was a waste of 20€

They were installed in a Fiesta MK7 2008 on the large scale.
Nice pure white color.
The brightness intensity is considerably lower than the factory ones. Probably due to the shade. In complete darkness they are good, but in narrow streets in the city, if you want to play with the scale to alert any approaching drivers at an intersection, I don't know to what extent they will see the light.
In terms of appearance, they are awesome.

I put them on a large scale because in the middle I have LED lights to match the color. They have a white color of 4300k (not like LED lights, of course), but their intensity is lower compared to the factory ones. Nevertheless, they are worth it because you can see and they have a good appearance.

I give them two stars, only because of their low price. You don't cry for your money, because otherwise, their intensity is disappointing. Easy to install and very nice color. That's it. If you want a serious upgrade of your lighting, give something more and put in LED or xenon. Simple and understandable.
