I am wondering how the PIAA spark 8000k's would compare to that of other non HID headlights around? I haven't gotten mine yet but I ordered a set of H1 and H3's for my hatch and i'm wondering if i spent too much on non HID's or are they worth it?
I also would be concerned with light oputput on an 8000K non-xenon bulb. My buddy runs 10000K xenons and I don't think they are as bright as my 55W PIAA Hyperwhite (or whatever they were called) bulbs, and those aren't xenon. Is the colour the look you are going for or just the white-ish HID look overall? I'll look at the bulbs I had on before my HIDs when I get home and let you know the specific name, they were very bright and looked quite a bit whiter than the stock bulbs did (though nowhere close to 6000K+)
i'm not worried about being able to see with these as i've seen a comparison of stock vs. these on an 06' ford fusion which is very similar to our setup. i'll have pics when i get em'. i am going for the bluish look these have but i've also been told they are brighter than the piaa hyperwhite's.
I use the PIAA Extreme White not the spark blue. When I was shopping for bulbs, I was considering the spark blue but read reviews that they are dimmer than extreme white. If you think about it, it makes sense that the white is brighter than the blue for the same 55W power.
If you want the spark blue then go ahead and get it. It's your car!
I put them on our Tribute and they looked cool to me, she did not like the color but as far as light output, HORRIBLE!. Now I put a set of HIDs in and they were worth every penny. I put 8000K in because I already had the bulbs but if you are concerned with light output go with 4300K.
