best HIDs?

[chamilton89]

How is 4300K yellow when all you see from everyone else is 3000-3500 K?

I had 4300's and they were pretty blue to me.

But no more blue than all of the other factory HID's I've seen.

A lot of HID manufactures use a fairly arbirtary "color temperature" numbers, thus why there is disagreement on the viewable colors given at each color temperature. Color temperature is measured in (K) or Kelvin and is biased on an actual temperature of a black body radiator which radiates light at a specific hue, this hue, is the "color temperature" of a light source. Because the color temperature of 5500k correlates to the sun and the widest color band frequencies (a scale on which all spectrums of visible light are graphed), it is safe to say that the bulbs that most closely mimics that of the sun, is the brightest and easiest for our eyes to see since the band is fairly smooth without any harsh peaks. Somewhere between a warmer 5000k to a bit cooler 6000k is the "brightest" bulb although technically higher frequencies or warmer colors (red) are scientifically brighter. Therefore, although we may argue on which color temperature is "best", science says that the accurate color temperature of somewhere between 5000k and 6000k is your best bet albeit not the brightest.

Moreover, the colour rendering index (CRI) of tungsten-halogen headlamps (≥0.98) is much closer than that of HID headlamps (~0.75) to standardised sunlight (1.00). Studies have shown no significant safety effect of this degree of CRI variation in headlighting.

Yup, you are completely right, standard halogen bulbs reproduce light with a wider frequency band, whereas HID's have much higher frequency peaks, therefor are normally not as faithful at reproducing objects. Just another way to show the quality of light.

Hey everyone again. I have 2 more questions. I have the spyder halo lights and i want to buy a set of hids for the high beams. Are they 9007 like the normal stock bulbs? And when i get a set should i get the High and Low beam ones just in case i switch back to my regular headlights for any reason? Or can i only get the single because the high beam bulb isnt on unless you hit the high beams. Thanks

I dont believe they are the 9007 bulbs that normally fit in our housings. I believe they are H3s for the projectors but I don't know what they are for the high beams. Should be able to to find out if you search through the threads.
