Philips H11 CrystalVision Ultra Upgraded Bright White Headlight Bulb, 2 Pack

These car lights are super bright and made a big difference when driving at night. Installation was easy and they fit perfectly. The visibility on the road is much better now.

I am rarely impressed by a product but in this case I am compelled to review it. I put these into my 2015 Buick Encore which from the factory comes with projectors but a bulb that to my eye measures at under 3000K and is very yellow. This is how all these Encores are and the light output on the road especially when its blacktop is just horrible. You can see the car coming down the road and identify it as an Encore because the lights are so much yellower than almost any other car on the road. I have been going back and forth on which Halogen upgrade lights to get or whether I should just go to the LED conversions but for the $23 I figured these were at least worth a shot. And they 100% were! I am fully impressed with the difference. While its hard to say if there is "more" light coverage on the road, what is easy to say is that the brightness provided by the simple color temperature change is something to see. These are rated at about 3600-3700K and are very much a bright white light. I tried to capture it in the pictures and you can see the difference, but in person the difference is even more pronounced. The left headlight is the Crystal Vision and the right one is the OEM. If these lights went up by 600-800 degrees K in color then they are worth every penny over the OEM lights specific to a Buick Encore or similar vehicles. My advice would be, that if your lights are visibly yellow, pull the trigger on these Crystal Visions, you won't be disappointed. Also, they are in no way blue. Pure white.

I received my Crystal Vision bulbs yesterday and was super excited to install them on my 06 GTO. The stock bulbs were yellow and dim, especially for projectors. I had purchased a cheap pair of 5000K H9's and modified the socket to fit the H11 plug. I was looking for a bright white light with no blue in it to match my LED fog light bulbs. Color was spot on with the H9's but light output was lacking and one burned out in a month. It was just an experiment and finding the right H9's proved to be difficult and relatively expensive. Bought the Philips bulbs expecting that bright white light with no yellow and installed them during the day. Sadly the light had a very faint yellowish tint in the daylight and initially I was disappointed because the color didn't match the fogs. However got a chance to drive the car tonight in the dark and color (see what I did there lol) me impressed and no longer disappointed. These bulbs are amazing in the dark and at a great price to boot. The color still has a tiny bit of yellow and still don't match the fogs exactly but it's close enough for my OCD not to kick in because of the usable light they produce. They blow away the OEM's and provide a ton more illumination than the H9's. My car is Australian built so it runs the lights anytime the car is on but at lower wattage during the day in daytime running light mode so we'll see how long these last. For the price though I'm already satisfied for what I paid, would have left 5 stars if the yellow color wasn't present.

I’ve purchased these bulbs for my Legacy projector H11 low beams several times. These bulbs are excellent. Unlike LEDs, these are safe, legal, and very bright in a projector(low beam) lens setup. I usually get about a year for a pair. - totally worth it. Much whiter and brighter than stock, but not “in your face ridiculous” like a lot of the illegal LED bulbs people are using these days. These strike a great balance. I’ve considered going all LED but decided to stay with these - LEDs look nice, but have much shorter illuminating distance than these. So after some trial and error I found the perfect combination - these H11s in my low beams, and a pair of Philips LED in my fog lights (6000k) - this combination works PERFECT - the h11s give you the distance and the LED fogs fill out everything close and around the front of the car - perfect combination and I totally recommend it. The key is to make sure you use the same or very close color temperature on all the lighting to get a nice even illumination that is consistent - very important.

Update - February 2018: The warranty for these bulbs says they're good for two years at up to 3 hours use per day. I use them about two hours most days on my long commute, so I thought I'd see how well the warranty works. Pretty darn good, it turns out. After an email to Philips, they requested some info (receipt, several pictures, etc.) that I sent off several days later. Six weeks later, just when I was going to email them again, I got a FEDEX package with a two-pack of the bulbs as a replacement; good way to keep a customer. Excellent customer service, so I'll bump the review up from 4-star to 5-star. The other original bulb is still going strong, so maybe my failed one was just an infant failure. Original Review: Well, on the one hand, these do a great job of lighting up the road. I live in a rural area with no street lights anywhere, and the light from these bulbs is crisp and white and a huge improvement over the OEM lights that came with my Mazda3. On the other hand, after just one year, one bulb has burned out after less than 300 hours of use, a poor lifetime as far as I'm concerned. The second bulb is still working fine, but for a "long life" bulb, this is not a good performer. I'll probably re-order this time, but if I continue to get short life spans from these bulbs, I'll move onto something else.

I bought these and had an electrician to put them on my accord 2015 low beam hoping to improve road visibility, They turned to be worse and low dim as if I have no light.I I went to another electrician last night after i wrote my initial review on amazon. He told me the bulbs were not installed properly. He fixed the installation and the visibility is much better, excellent

Buen producto

Awesome brightness and white light for the foglamps, happy I chose the globes.

Good quality, bright as describe in specification, semi-white in color.

اللون ليس ابيض و إنما هو اصفر لكنه يصل لمدى بعيد و جيد نوعا ما
