Hey Guys maybe you can help me out a bit, and give me some of your imput on this subject. I am trying to compare each of these bulbs


PIAA HID SUPER COBALT HID 6600k


AND

Philips 6000K Ultinon D2R


I have seen many of the Philips Ultinon Bulbs around these Forums, and was very impressed and liked them a lot, but I saw the PIAA's and haven't seen those here. So Lets get some imput On these bulbs

Here are a few specs on each bulbs


PIAA HID SUPER COBALT HID 6600k

Only the highest-grade materials are selected for use in these products and to ensure your complete satisfaction, every PIAA bulb is 100% tested at each step in the manufacturing process. Absolutely nothing is left to chance!



Philips 6000K Ultinon
Price: Roughly $230.00

6000K color temperature
Contains indium iodide to create extra blue light
This Xenon bulb is for Reflector Headlights

(Description Taken Off Amazon)
This is the best Xenon Bulb on the market. Providing the best lumen and color combination. Don't be fooled by the higher Kelvin rating Xenon Bulbs. They are very weak when comes to light output. This Xenon bulb is for reflector headlights. This is for a pair of Philips Ultinon 6000K D2R Xenon Bulb made in Germany with 1 year limited warranty. The Ultinon family of automotive discharge lamps was introduced by Philips to meet the significant aftermarket demand for head lighting units having a 6000K color temperature, higher than the standard 4100K type. The 4100K lamps can produce headlight beams of distinctly different colors depending on the design of the optical system into which they are incorporated. Many HID headlights now employ projection lens systems which capture all light from the lamp, thoroughly homogenize it, and then project a uniform color beam out through a mask and lens. Color variation from one projection system to another is minimal, the only difference sometimes occurring around the edge of the beam where chromatic aberrations from imperfect lenses may give the beam a purple colored lining. However with 4100K lamps in reflector style headlights, the beam will often be found to have a yellow or green color in the upper areas. The light here originates from the lower portion of the reflector. Light hitting that part of the reflector must pass through the lower half of the arc tube in which the pool of yellow-colored molten metal halide salts resides, and much of the blue light is therefore filtered out in this area. This greenish-yellow tinge is considered to be most unsightly in the aftermarket, a bluer light being strongly preferred. To satisfy this market Philips introduced this higher color temperature 6000K lamp whose dose contains indium iodide to create extra blue light. This is for a set of 2 Philips Ultinon Xenon Burners.

I have the Piaa 6600K's and I LOVE EM!

 

If you must go Philips 6000K Ultinon D2R. PIAA are not worth the extra money.

 

definitely get the PIAAs. i had them on my car and they look amazing. kinda gives a purple-ish look to it. i had 3 friends get them after i did. i wish they made some D1S but unfortunately they didn't cuz i missed them. $390 seems kinda high. i got mine at a local shop for only $290.

 

piaas do tend to burn out quicker...i like my ultinons esp since i paid 200 for a new pair

 

Ok Cool, do you know of any bulbs that will match the Piaa's good? Because I haven't seen any piaa bulbs that looked like that
