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

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.

Obviously check with the dealer or manufacturer to make sure these bulbs fit your car BEFORE opening the packaging and installing them. WEAR CLEAN GLOVES!!! In terms of comparisons, this is a standard size light bulb. It is brighter than the OEMs. It is not as bright as HIDs or LEDs, but that costs more money and more effort, not to mention you may have a convertor box flopping around in the front of your engine when you drive. In a standard Toyota, for headlights, its fairly easy to reach the existing bulb and make a quarter turn and pull out, to remove the bulb. Do be careful, as the power cable would still be attached at this point. This fit several years of Camrys, Corollas, and Priuses, that I helped my friends change out. It's not that hard, but they wouldn't touch it. I've found that removing the dead bulb first and then removing the cable is easier, but it depends on the car, and there are plenty of youtube videos to follow. These bulbs burn brighter than OEMs, so the lifetime is not quite as long as what came with a car but the difference is noticeable between the standard orange/yellowish light versus this bright white light (not blue from what I can see).

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.

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.

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.

They worked; however, they were not as bright as I thought they were going to be (compared to the OEM "standard bulbs" I had from the dealership) and they did not last as long as I thought they would. This may be my fault, and I may have had too high of expectations for them, or my expectations may have been unrealistic; but I thought they were going to be significantly brighter (at least than the OEM bulbs) and last more than just around 1 year (plus or minus a few months). I installed with gloves on, made sure I didn't get any oil/grease/fingerprints on them, but they still burned out around 1 year later. I've bought different bulbs since then (a couple of times over), and I have to admit I was disappointed in all of them as well, and have only been pleasantly surprised/satisfied once I went to LED bulbs. LED bulbs are now almost as easy to install, are bright (without being blindingly bright), and have lasted more than a year so far. Worth the little extra $$$ in the short run, and will save $$$/headaches/issues in the long run.

Outstanding set of bulbs lasted over 7.4 years with just one burning out today. No complaints, car has Daytime running lights that are on all the time.

Two major problems with the Amazon product/description by the manufacturer. 1) The average service life is 150 hours. 2) The color temperature is not 4000K as advertised, it is around 3500K. Average service life according to the package is 150 hours. The vehicle that this is installed logs 45 minutes each way in the night for 5 days a week during the night. That makes minimum of 1.5 hours /day * 5 days = 7.5 hours/week. This means 20 weeks at best for me. So, the light bulbs will burn out in about 3-4 month. So, I will have to shell out another 30$ in about 3-4 month. The color of light bulb is about as same as the OEM bulb and is not white at all. In comparison to HID light on my other car, this bulb definitely have yellowish tint. So, if you like changing bulbs every 3-4 month, and yellowish hue, then get this. I purchased this for a car which requires removal of bumper to install the light bulbs which takes about 1 hours. I have Cadillac CTS which requires H11 halogen light bulbs. This bulb fits and works fine after install. However, due to my non-exhaustive reading of the reviews, I purchased this due to the name brand. However, after purchasing I noticed that the package indicates 150 hours service life and 3500K color temperature, contrary to the Amazon web description (or lack there of). The light is as bright as original OEM light bulb which lasted 7 years of mostly night driving. But, I suspect the bulbs will burn out in about 3-4 month. In another word this bulb will last 1/20th of the OEM light bulb. HOW PATHETIC performance. You are warned. GO, buy something else, and don't make the same mistake as I have.

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

These bulbs are very white and seems a lot brighter than the OEM ones that came on the SIenna. So far after more than a year the bulbs are lasting just fine. Update July 2021: Installed in Mar 2019 and the driver's side burnt out in July 2021 so almost 2.5 yrs of use which was more than I expected - not bad for a higher output bulb.

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

Phillips es líder en iluminación, los focos sin fabricados en Alemania, definitivamente si se nota la diferencia entre el normal y el cristal visión, la ventaja de estos es que son de halogeno, y tienen mejor amplitud de luz que los xenón, y al instante es el brillo no tienes que esperar a que lleguen al máximo a la hora de encender, para algunas personas es alto el precio pero la calidad es inmejorable, en mi caso el paquete traía unos pequeños focos incluídos, como les decimos en México de pellizco. Ya l vez en la foto no se aprecia muy bien por el sol pero definitivamente si es blanca la luz a diferencia del normal. Los recomiendo.

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