I only changed the one burned out on a Hyundai Tucson 2020. Due to difficulty of access, I left the good one. If you don't know WHICH ones you changed, you won't notice any difference. It's minimal and only in the shade. The light is a liiiittle bit whiter. If I find time, I will do tests against a wall but also with other cheap simple Philips ones I got at the same time, to see the difference.

Two H7s were installed in a 2008 Leon, good light, poor reliability, one burned out in 2 years with very reasonable use, the previous ones lasted over a decade, sorry, not recommended!..

Tragic performance! Not +150% as claimed by the manufacturer, but they don't even illuminate decently! I replaced one crystal vision from the pair I had installed for years, and on the road, I thought only the old bulb was working! I'm thinking maybe I bought some monkey instead of Philips...

X-tremeVision Pro150 H7 3700K The light is not white. Maybe a little whiter than the old bulbs. The intensity is a little, I would say, brighter than the old ones. They definitely don't do what they promise!! And definitely... they are not worth their high price!

Installed on headlights with projector very satisfied. It concerns the xtreme vision pro 150%

They replaced the mom bulbs in Citroen C4/2012 and there was a difference in brightness but not 150% (seriously, what criteria do they use for these prices???)
After about 5 years, one burned out and because I couldn't find the same ones, I used one of the mom bulbs that I had kept so as not to be one-eyed. Having one mom bulb and one Philips, their difference is now negligible - maybe because of the 5-year gap... You have to pay very close attention to see that the Philips shines a liiiittle bit more. I don't notice any difference when driving at night. I don't consider them that expensive, but they definitely don't do what they claim...

The 3600K color is almost the same as the regular bulb in terms of intensity, but it is indeed brighter in the machine that I installed it in a car. I don't know if the difference would be noticeable

They might be bothersome. The intensity is very good, the illumination is very far and the beam of light is very good. Because they illuminate far, they have sometimes caused me to signal. During the day, the lights appear slightly yellow while at night they are whiter.

Quite good lighting especially in rainy conditions. I would like them to have a little more intensity.
Regards
The downside is that they do not withstand over time, they burn quickly, but in terms of visibility, I think they are the best, both in rainy conditions and in general as transparency, better than temperatures of 4000 K.
I am seriously considering buying them again despite not having great durability over time.

In no case does it resemble Xenon. I start by writing this to prevent someone who is not looking for simple bulbs but wants them to be white like Xenon. Among the simple common bulbs, they may be the best. They do shine far away and their color is between yellow and white. As for their durability, I cannot know yet because I have had them for a week. However, remember that the headlight has a great responsibility, if it gets moisture, no matter what you put, it will burn

A little bit expensive, very good light, unfortunately it only lasts as long as the manufacturer says in the description. I have been using them for years now.

Wonderful set! I used to wear it until recently on a Golf MK7 with conventional headlights (with mirrors). Very clean light in white shade and amazing clarity on the road. I wore them for about 1.5 years and then changed headlights. I highly recommend it without hesitation!!!!

Very satisfied. There is a big difference from the previous lights (Xenon type) that I had.

Let's see how long they will last.

They are slightly better than the factory ones, but nothing extraordinary. Their good thing is that you can see very well in the rain compared to the diamond vision. They are good for their price

They have a stronger beam than the factory ones. Definitely 50% more efficient. I have had them for 2.5 years at a purchase price of 206.15€. When I installed them, they were slightly whiter than the factory bulbs, but over time they yellowed a lot. The last part is their only negative aspect.

Very strong lighting without being bothersome, but not a particularly unique shade (almost classic). Their lifespan is unacceptably short as both burned out within a week (normal since they have the same lifespan), which proves that their durability is indeed short from their construction. I don't live in Sweden for the lights to be always on. I wouldn't buy them again!

Average bulbs from a top manufacturer. The companies that produce bulbs are Philips and Osram, so I chose the first one. The light they produce is at 3500K, therefore it is slightly whiter than the factory ones, without being anything fancy. They are satisfactory in practice, but I was not impressed by their performance. The set lasted me 2 years in intense use. When I replaced them (with the same set for inexplicable reasons), I saw a remarkable difference between the old and the new, which means that there is a significant decrease in performance over time. However, I cannot reliably compare this with other brands and bulbs.

Their light is indeed much better than the factory ones, but their appearance in no way has a white shade as advertised. They are purely yellow with a hint of white

2/5 because it is simply better than the traditional one (by 5-10%), but still very expensive. Clearly prefer LED.

Very good. The difference is obvious compared to the regular ones. Their durability will show, because two previous models I had burned out relatively quickly.
