No, the color temperature of the bulbs has nothing to do with brightness (or lumens). It's just coincidence that most 4100k-5000k will outperform 6000k+ bulbs. That's because some bulbs labeled 6000k+ are actually just 4100k bulbs with a color filter on the capsule.


Where are you getting this info from? I must totally disagree with you on this one. If you were correct, than every piece of information on HIDs I have is wrong. That is the whole point of the Gen 1 and Gen 2 HIDs. The first ones were 4800K and the latter are 6000K. Now they even have 8000K. Are you suggesting that these are just mere labels? In addition, a true HID bulb must have a totally clear capsule. Like Antonio said earlier, those with the colored capsules are total garbage... The color of the light is indeed determined whether it is 4800K, 6000K, 8000K or whatever else there is...

Now, if I understand Antonio correctly, he's saying that the D2S capsules create a better light pattern in our stock halogen headlight compared to the D2R. From other readings, I understand that the light color is usually yellower than expected, again as as result of using HID capsules in halogen headlight assemblies, thus the demand for HIDs with higher color temps.

The light pattern varies only due to the stripe on the D2R capsules, not due to it being used in halogen housings. The capsule will produce the same color as it does in OEM applications, but it will not be reflected properly, thus loosing its performance...
