PHILIPSH11 CrystalVision Ultra Upgraded Bright White Headlight Bulb, 2 Pack

Received "CrystalVision", not "CystalVision Ultra" (which seems to have been discontinued). Output is 4300k. Two W5W bulbs were also included. The specs indicate this item is not street legal, so keep that in mind (seems to be a technicality, they are far less blinding than many new cars).Despite all that, I'm satisified with the product as they are brighter and whiter than the OEM bulbs. Will update rating if they last less than a year.

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.

Made a brighter vierw

I got these to replace dead bulbs in a 2011 Toyota Prius. I was kind of skeptical about these bulbs being so much better than the "standard" headlights, manufacturers do have a tendency to be somewhat dishonest about those types of numbers by intentionally making comparisons with the worst alternative possible without putting themselves at excessive risk of losing a lawsuit for false advertising, after all. After installing them and driving for a bit at night with them on, however, I'm impressed enough with them that I can't say I'm inclined to argue specifics.Since both prior bulbs are dead, I had no stock bulbs to directly compare with and can't make any guesses as to percentage improvement or anything, but I would not be at all surprised if they are, in fact, significantly better than the stock bulbs, even if they're not as much of an improvement as advertised. This is of course, assuming my memory is serving correctly regarding the illumination provided by the old bulbs, although I don't feel a particular need to doubt that.I did have some difficulty installing them, and almost returned them thinking they were the incorrect part, but that ended up being the fault partially of myself and partially of Toyota's somewhat vague manual/instructions (coming from someone used to doing computer repairs and dealing with vague instructions/diagrams in that context). As it turned out, though, I had simply not seen the sockets for the low beams and had accidentally tried to replace one of the high beams with these, the bases of which are keyed differently to help let the user know which is which, but I mistook as an indicator of having bought the wrong product since I'm a neophyte to car repairs.

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.

They will last about 6 months before burning out.

They worked over a year and for the price thats just okay and probably a good thing because I ended up replacing with a more expensive H11 bulb for a wider, brighter beam since I drive dark, winding roads. Both bulbs failed within a week of each other and I always installing the bulbs to keep them clean.
