headlights
I love projection beam head lights but I have done some testing and I have taken junk head lights and have painted the lower half of the reflectors and put in plug and play HID and the cut off is clean.
*No sarcasm included just to clear up any confusion lol*
If we were to look at a perfectly round reflector based headlight the part you see in black below is the portion that is painted black. This portion is responsible for upward and upward-side lighting, the portion that oncoming drivers complain about with a plug and play HID set up.
If you ever look at a reflector based HID head lamp you will notice there is no light coming from the lower half of the head lamp. I'm not too sure how this accomplished but there must be some sort of shield blocking the light from reaching the lower reflector half.
Some of you can try doing this with a cheap flash light as I did, painting the lower portion of the reflector then shining the light on a wall in the dark and it will give you an idea what can be accomplished for someone who is super frugal.
After I did that I bought a junk headlight at the junk yard for $10, baked it open, painted the lower half flat black, snagged a super cheap PnP HID kit and it performed in the same manner.
I hope to do this again real soon to post up some pics of the cut off.

Im curious about this too.
Sure I said that, but where do I say "blue light is the brightest out there". I didn't. The end.
And before you go twisting my words to make yourself look smart; As I go on to explain in that thread, I based my opinion of the color and brightness of 6000k HID bulbs on my particular setup, which was actually closer to the 5000k bulb that appears in a picture in that thread.

Well, take that how you want (and that particular quote is taken out of context), but it is true that the higher the kelvin, the brighter something is. Notice how I also mention usable light bodyguard.
Yes. Instead of a current running through a filament it runs through xenon gas thus creatin an arc inside the bulb of an HID bulb. Depending on the current, ballast, kelvin rating of the bulb, or any other varibale, photons of a given wavelength will be emitted. From there the photons will be focused through a projector lens or in most cases straight out of the headlight housing lense. If you find any of this erroneous, please feel free to correct it.
In a general sense, the K color rating has absolutely nothing at all to do with brightness. They are measured completely independently of each other.
Now with HID capsules, the higher the K the lower the actual light output. This is entirely due to how the light is created, and is not a general concept.

It depends on your definition of "bright". Within the Earth's atmosphere, blue light is the "brightest". A blue H.I.D would produce the most "daylight" looking projection.
K and brightness are directly related. My general statement "...the brighter the kelvin, the brighter something is..." was just that, a general statement, not meant to be about HIDs. If you read the original thread, you'd understand that. As I said, the quote (while not altered) was taken out of context.
