thx for the comments...........keep em comming........shouldve made this into a pollPowerDrift said:PIAA is "whiter" than Phillips. I had both, but the Phillips provide more light on the road and a longer beam. I often drive on back roads with no lighting as I live in suburbs.
Although the PIAA's were real white and bright in front of the car, it sucked for illumination. I had to use my highbeams more often cause I couldn't see too far down a pitch black road. I didn't have this problem with the phillips blue visions, but they are defintely not very white. If you want a white bulb, just between these 2, PIAA is white.
I heard the Sylvannia Silverstar were a lot whiter than the phillips and provide equivalent illumination. Too bad they don't make them H7 sizes :sad:
please dooo, i want to see how much whiter they are with the XENONS turned onblatt22 said:I just bought a pair of Phillips blue visions H7. They just increased them to 4000K, compared to previous 3500K. I was told by the tech people where I bought them that they were better then the Sylvanias. So, I went that route.
I went with these because they provide better lighting than the PIAAs. Which is the whole point of upgrading.
Have yet to install....will post pics when i do.
Don't quote me on this, but that last time I talked to someone that worked at Phillips, they told me that the Bluevisions were basically their Vision Plus bulbs with a blue filter. This is how they are able to provide a teeny bit more light output than the regular halogens bulbs and still achieve the whiter light.Atlas said:IMO, the bluevisions don't really give any advantage over stock halogens in terms of brightness, except for the white look. If you want illumination, try Phillips VisionPlus - those bulbs provide much more illumination than stock or the PIAAs. Just won't get that ricey blue/white effect if that's what you're craving.
