Visit us at hidconcept.com.

FYI, see below comparison photos to see how it looks different from the stock 4300K (from our previous test)
(First comparison photos were taken from our facility. The other two actual road comparison photos were taken by AUDIZINE members. Many thanks to kappax12 and studioRS!)
There were rumors that X-tremeVision bulb gets whiter and brighter after 200 hrs of use.
To find out if it's a rumor or truth, we ran a test by having a X-tremeVision bulb stay lit for 9 days (9 days x 24 hrs = 216 hrs).

Conclusion: It's not a rumor anymore. It has been confirmed. X-tremeVision bulb gives whiter and brighter light compared to the stock 4300K bulb from the beginning and it gets even better as it goes through break-in process.
We're very satisfied with the result after 216 hrs of use.

We took a few comparison photos showing stock Philips 4300K D2S(lower), new Philips X-tremeVision D2S (middle), and color-shifted Philips X-tremeVision D2S w/220 hrs use (upper) to show you the difference in lighting output and color.
The photos have not been photoshopped and untouched except for our log being added.

Although we tried to take good photos, it is not easy to take photo of lighting.
The result is that stock 4300K is noticeably yellower and dimmer than X-tremeVision bulb and the color-shifted X-tremeVision bulb is much whiter with crisp white.

But seeing the photos, I have to disagree. This is somehow achieved without modifying the actual lens; so i'm pretty impressed. Overall I wouldn't say it's a HUGE gain. Also HIDConcept prices can't be beat and it's an authentic bulb, no risk of knockoffs on ebay.

Excellent bulbs!

I know those pictures are horrible, but its the best I could do. They don't do these bulbs justice. It's great being able to see again at night. I can't even tell a difference when i turn on my fogs now, when before my fogs were brighter than my having my brights on. These bulbs are brighter then they look in the pictures. I like the color too. They're a nice crisp white. Would definitely recommend these.

Thank You,

Some things I just wasn't meant to understand. For example, the fascination with 'white' lighting. In scientific circles it is well understood that a lower temperature light (in the 4000 to 5000deg K range) is superior than whiter light for automotive headlight applications. There are several very sounds reasons for this, which I would be happy to enumerate if anyone is interested. But in brief lower temperature light produces a lot less glare and provides for much better depth of field, both important for nighttime driving. I guess the point is don't be fooled into thinking whiter light is superior.

Thanks for your comment.
It WAS normal for HID to have higher kelvin (whiter/bluer) with less brightness but X-tremeVision series gives both whiter color as well as more brightness than stock. What did they do? It must be a secret recipe of Philips.

Yes, you are right that brightness is good but my point is that whiteness is not good. I admit that I don't know what Philips has done with the XtremeVision bulbs. I was in automotive lighting research early in my professional career but lost contact with my former associates years ago. What I hope they have done is to change the gas mix in the bulb slightly so that it emits more visible light in the lower frequency band of the visible light spectrum, but then that wouldn't comport with the whiteness claim they are making which usually means a boost in the blue-violet end of the spectrum, which causes glare and the loss of depth of field that I mentioned above. The only way i know to increase brightness is to use a slightly higher wattage. HID bulbs can do this easily without over heating which is the beauty of HID over halogen lighting. Halogen lighting though is a wonderful quality of light, just not particularly efficient compared to HID. The dumbest thing in automotive lighting though is the blue tinted halogen bulbs that so many people buy these days. Crazy world.

Well, based on numerous comments and feedbacks we received from many customers as well as our own in-house in-depth testing, we confirmed that it is very clear, whiter, and brighter.
Feel free to do search on the forum to find many comparison photos posted by true customers.
We are not rocket scientists here testing them by taking them apart but when it comes to lighting, we know what is bright and white. :D

I personally stick to 5000K bulbs in all my vehicles. I do notice better reflection from the white lines on roads with 5000K over 4300K. You are right that there is less light output, but I can say the higher K stuff makes the painted white lines shine more.
