I have been buying them for years and in many forms H1, H7, H4, H11, I don't have much to say, it is a very good and reliable bulb, the closest to a 5000K look. It is a very good choice for someone who has a car with canbus and does not want to install either Chinese led canbus kits or spend money on an expensive led kit so that it is reliable, has clean light, and does not blind others. Now, in terms of light, it has a little less than the classic transparent (yellow light), but in my opinion, it is not something annoying.

I read about the "diamond" lighting they provide and bought them without a second thought... and while I was expecting them to elevate my car's lighting, I regret to inform you, dear friends, that I was bitterly disappointed. These bulbs are probably for other drivers to notice you, not for you to see... in the end, not everything that shines is a... "diamond"!!!! I consider the second star generous...

To change the light bulb, you have to know the length of the glass so that the beam is the same. If you have a bad beam, then you have to change the bulb, maybe try a different type or different brand. For those of you who say that you don't have a beam, try them first in a truly dark area, like a mountain, and if you don't like their beam, they aren't for you. Inside the city, there is now sufficient lighting to need your own lights

Economical and at the same time, I would say they are of good quality.
I have installed them for about 6 months now without any problem.
In general, white lights do not help in case of fog, so if you live in a place where it is a common phenomenon, avoid them and stick to the yellow color.

My review is exclusively about the PHILIPS DIAMOND VISION ULTIMATE WHITE LIGHT in H4 at 5000k.

The bulbs are quite white and have levels close to the xenon look (I would say it's close). It has a nice brightness with a nice spread and gives me the impression that the beam has increased by a few meters.

The light has a whiter color, no comparison to the regular bulbs I had before.

And of course, you don't have the known problems that xenon lights have, where they hit their light here and there and blind the opposite drivers.

I would describe it as a quite reliable choice for anyone who wants to improve the lighting in their car without having the problems of xenon.

And of course, with the quality of PHILIPS.

I changed both bulbs for better ones, but they don't have enough power and maybe the cool white color is to blame, resulting in me not being able to see the road well. I will probably put back the previous ones with the warm white color that I could see better with.

The photos are before and after, it is a very beautiful white that bluish, the first step is quite weak, do not expect it to illuminate much, but at the same time when you turn on the headlights it illuminates much better and in a completely dark road, I do not know if it blinds the opposite because obviously I am not a fool and when I encounter a vehicle from the opposite direction I lower the ladder on the lights.... satisfied, I will come back in the future to comment on its duration...
Unfortunately, I returned very early to complete the review, after a few kilometers and a very short time the bulb burned out, meaning the first step burned out because the larger ones continue to work, but I cannot drive because I will blind everyone opposite, I will replace it with something of the same price level and see

Attention. They are not suitable for rainy and foggy cities. They are approved only for mountain with absolute darkness and exhibitions. Far away.

Very low intensity in lumens compared to the Philips Extreme (950 vs 1650). The light flickers when it's turned off and I didn't like it at all. It produces a 5000k color, but without intensity and with the flickering of the light, I definitely don't consider them a good choice.

Very beautiful white color, I would like them with a slightly stronger lighting. The bulbs are aimed at those who have halogen bulb requirements! I will not choose LED and Chinese xenon bulbs of €20 - €50 again!

After the diamond vision, which looked nice on the outside but had poor and dangerous lighting, especially in rain or snow, I installed the white vision, which were quite good but burned out, probably due to my own mistake, after 3 years of minimal nighttime use. The photo I have is of the whitevision ultra and I am completely satisfied with them, both in terms of brightness and range. (I want them to match with angel eyes fog lights). Now, in rain or snow, the visibility is definitely slightly more limited

Medium lighting intensity. Easy installation, very nice white light but they do not illuminate well. In photometric measurements, they had the worst performance compared to most bulbs. For €10 in H4, it's okay though.

Really bad bulbs. They don't illuminate at all. Almost every night I checked if I had actually turned on the lights in the car. And besides that, one bulb burned out in about 3 months. Unacceptable for a branded product.

These specific bulbs are simply and only for aesthetic purposes, because in terms of light, they are simply disappointing. They have a 5000K color temperature and the light they emit is cold white and very close to xenon, but they lack proper illumination. There is poor visibility at night, both on small and large scales, let alone in fog where the overly white light does not help. I believe that the correct choice is lights that truly help us see properly at night, rather than just some bulbs that make the car look beautiful.
