HID question

None of these HIDs are anywhere close to white.

None of the companies you quoted here use the temperatures you are discussing. perhaps the manufacturer/vendor you bought from is giving you higher temperature ratings to increase sales?



# Anything over 5750 K and human vision and depth perception is significantly reduced
# Anything over 6000 K and the actual lighting output/power reduces exponentially
# Many companies claim to offer 8000- 12000 K Bulbs ...if this were true the headlight would shine DARK BLUE TO EVEN DARKER PURPLE !!


i won't argue with your lights, your pictures look great. i'm just wondering if your temperature scales are off because of some bad/false advertising.

Humara,

On that you could be correct. I dont know the actual scale. I only go by that they told me my lights are 10k , which is why I said in my above posts that any different brand could be totally different.

Also generally most people have said that 10k-12ks are purple. Well my 10k bulbs for my boxster are not purple at all but my lambo lights are purple and several HID companys I see on the road are purple, especially Audis. Purple means higher in temperature.

I also find it hard to belive that lamborghini and Audi, BMW are producing lights that are losing light output because they are purple. If that was the case I dont think they would make the temp that high, but almost every HID light I see at night has some purple in it. As I have stated before my purple lamborghini lights are a little bit (not much) brighter than my non purple HID Porsche lights.

audi, bmw etc are not producing 10000k lights. the color you see is from the projector lenses. and you answered your own question. 10k-12k are purple. your 10k are not purple. using simple logic, we can conclude that your bulbs are not 10k.

Cars on the road appear to have blue lights when compared to all the other halogens out there. Halogens are actually
yellowish, and that yellow makes xenons appear blue. I assure you, they're quite close to white.

And it's the projectors that produce a tinge of a violet color, and that's usually on the edges of the beam pattern
(like curved/angled glass create a prism).

It's hard to tell from a digital picture real life results. And when it comes to light and cameras, there are a lot of
factors to consider (white balancing, color correction, position/angle, etc.)
Side note, did you know digital cameras can pick up light the human eye can't see? Look at your digital camera's screen while aiming
your TV remote at it (while pressing a button).

I will say this, the old Porsches did seem to have a greenish tint to me. Those were among the first xenons out there.

I find it funny that many of the vendors show what the lights look like head on. What should matter is how it illuminates
from within the car.

Well you could be correct. Alot of people say that 12k and up are purple, and 10k are deep blue.

So what color / temp would you say the lambo lights are from the above picture? Note that the picture looks exactly how they look at night, its not distorted from the camera.

Remember, the edges of the beam/pattern could have the prism effect... Coupled with the fact that the angle of
projection on the Lambo is so tight (due to how low the headlights are positioned), it looks like it has more violet
than what actually spills out on the road.

Did that make any sense?

Yea I gotcha. But saying that the edges "could" have the prism effect is purely a guess.

If you want the most light output, go with 4300K. ALL factory HIDs are 4300K. 6000K is used on the Le Mans cars, but at a higher wattage than the 35W capsules we get for the street. The difference between 4300K and 6000K is the mixture of the gases inside the capsule that insulate the arc. 6000K capsules produce a bit less light than 4300K will. Anything over 6000K is created by coating the capsule blue and thus significantly reduces the light output. I have replaced a pair of capsules in a BMW with 6000k when one burned out, and did enjoy the result.

Now, for the debate over putting aftermarket HIDs into conventional, halogen housings- not a good idea. You can get away with it in a projector type assembly, as you have a focused lens controlling where the light goes, but in a reflector type housing (which the halogen Porsche assemblies are) its a horrible idea. All those aftermarket companies do is take a standard D2S or D2R HID capsule, and mold it into a halogen bulb base so you can stick it into your assembly. The problem is that the source of the light output is different from a bulb to an HID capsule (generally much more forward in the case of the HID capsule, which is not what the reflector was designed for), and you wind up with horrible amounts of spill and an often very incorrect beam pattern. This is not only less than ideal to drive with but, much more importantly, is downright dangerous to oncoming cars as the result can be extremely blinding, and is illegal for the reasons I just outlined.

If you want HIDs, get factory Litronics.
