HID Color Temp

[Undisputed]

The stock bulbs are at 4300K right?
Colors get more blue the higher you go, then they get purple right? Also there is a decrease in light output the highter in the spectrum that you go.
Is this all correct?
Cause I'm wondering why when a BMW, Benz, or Lexus is behind me, their lights are pretty purple but they seem so much brighter than mine. I know it could just be that they are aimed too high, but they still seem like they're prettty bright. And the BMW's lights are really purple.

that's really sick, where is that light display? And the reasoning that the bmw's and lexus' lights are purple i think has to do with the fact that they are bixenon. If you ever see one behind you they also auto level a ton and change back and forth between yellowish and that purplish blue color. But if you ride next to one and you see what color they illuminate the road it's actually a shade of yellowish white. I can never figure out why this is. Cause coming from behind or from the front they always look slightly purple but the road is illuminated the same as any other low temp HID.

No, that's not it at all, nor is it the cutoff shield as some people think. The purple, blue, green appearance from off angles is the function of the light bending optic properties of the condenser lens. The color temperature has nothing to do with this. Our projector optics do that as well, but to a lesser degree.

Yup. For those of you that purchase euro lenses, they use a different cut off and glass lens, which gives you that reflective blue/purple look like the newer audi's.

Bi-xenons are simply hi and low beams in one, by using an adjusting shield or lens.

[AudiA4_20T]

almost every manufacturer is going to use 4300k because it is the brightest of them all

[Das General]

10k is brightest! and it is JDM purple, isn't that why Honda owners put them on their civics?

[Undisputed]

10K isn't brighter, it's just a color in the spectrum.

E-Codes?

[Das General]

E-Codes?

yup, and I was joking about the 10k

[JMRQuattro]

^^ haha yeah aren't they something like 20 times less bright in terms of lumens? But i actually read somewhere that the blue lights such as 10k appear brighter because of the color is easier to identify things that it lights up and also to oncoming cars blue is a more sensitive color to the human eye so you can see more of the light than you can with 4300k thus giving the illusion of brighter lights.

[Das General]

I used to run 6500k HIDs and they weren't nearly as bright as my 55watt 5000k setup.

E-codes are the best overall improvement, I can see miles with my setup.

[JMRQuattro]

i have 10k and i see plenty far. I light up objects as far as my eye can see, mostly road signs since they are reflective turn blue with my headlights on them so i can guage how far my headlights actually go. It's amazing how far i can see with them. And the width is great too, i can light up the entire width of the freeway. I love the color blue that they make everything too.

ok now that makes a lot of sense. I knew it had nothing to do with color temp, so i was thinking it had something to do with whatever system they are shining out of. I didn't even think of the projector lense. But that makes perfect sense seeing as how that could effect the length and direction of the light waves. Thank you for clearing that up because i've actually been trying to think of what could be the reasoning for that for quite some time now.

Great explanation, I always wondered why this was. I knew the lights weren't 10K or anything because I know what 10K looks like and the Lexus lights look white but with a purpleish glow to them.

[Undisputed]

If you wanted to up the color temp, then couldn't you also change to a 55w ballast and get a similiar output to the stock setup? Theoretically?

[JMRQuattro]

That sounds logical. I've never tried it or seen it done. You should ask mxrz, he's a light nazi lol. If anyone would know i would think it would be him. I've had conversations with him on other HID threads and he seems to know his shit pretty well, i get the feeling he must have a career dealing with light, especially seeing as how he has that pic of the color temperature display.

[mxrz]

35watt 6000K is about 2800 lumens. At 50watts, you're looking at 4000lm approximately. 8000K at 50watt will be about as bright as factory 4300K (3200lm).

[JMRQuattro]

^^ I had a feeling you would know. Now what would 10k look like? Cause i have 10k's on mine. So would 10 be just below factory 2800 or would it suffer even worse still?

[Das General]

Do you really want that look. IMO it is kind of ricey. But I understand it is your car.

[JMRQuattro]

^^ that's the 2nd time i've heard that. I really don't understand how that's ricey. My car is black and i think blue looks sick. Not sure how blue headlights got dubbed as "ricey". I see so many vw's with 8-10k, and i usually don't see many ricers with blue. If anything i think that yellow fogs are ricey. I see so many honda's and acura's with yellow fogs. IMO it's either match your headlights or don't change them!

[Elliott]

1000K (candle light) FTW!!

[Undisputed]

I was thinking 6000K. I'm not interested in 10K. That's definately riced out.

[JMRQuattro]

^^ another 10k rice comment??? what's with this. how is that rice? And since when is that necessarily a bad thing?? After all the Evo is a ricemobile . But i really don't see this color with rice association thing. Blue just happens to be my favorite color so i would rather have HID's in blue than yellow or white and looking like standard halogens. I'm telling you, yellow fogs is rice. Or even just straight yellow headlights all together (and i'm talking really yellow like the pic above for 3,000k). Someone please explain this reasoning for the rice calling. I can name at least 5 dubbers in my area with minimum 8k, and i can also name at least 10 ricers (mostly honda accords and acura RSX's) in my area with mismatch yellow fogs and 6k lows. And besides... white is the color of rice after all.

[El_Chapusca]

10k and over FTL civics and integras rock it like its the coolest shit ever

[Undisputed]

It's not necessarily the color. More like the combo of the blue headlamps, 3 foot tall rear wing, spinners, the cherry bomb exhaust, and the pictures of the naked girls on the mudflaps. lol.

[JMRQuattro]

how is blue not cool? I'm sorry but i really don't understand

[JMRQuattro]

wouldn't cherry bombs and naked girl mudflaps be hick?

[El_Chapusca]

Not feeling the blue also. That's O.D, Im talking about the "blue blue" they f-ing blind the shit outta ya. Even the new accorss and camry's are starting to rock this kelvin temp wtfff

[JMRQuattro]

Alright well they look sick from the driving point of view and even thought they blind they look good on coming as well. But whatever, i think blue looks really sick. Probably why it's my favorite color. But i've been looking to change anyway. Not sure if any of you will be happy at all with this one lol. PURPLE haha!! no one has them. I've only ever seen one car with purple and it was probably the sickest thing i've ever seen.

idk about you, but around here its played out. Seriously every honda,nissan,toyota from 1990 to 2008 have them. i think its even illegal in some states

[JMRQuattro]

around my area it's a large dubber community and ricers tend to be rare. Although i did see the most riced out car ever the other day. It was an 80's civic first of all and it had one of those ugly rear wings with the steal bars and a black top that literally was a foot taller than the roof of the car, it had some ugly ass black rims and the car was like slightly grey (but not a cool grey like dolphin grey) and he had the fattiest like 5" exhaust or some shit that sounded like he was driving a fuckin dirt bike down the street. I wanted to slap him in the face for having such shitty taste. But for the most part ricers aren't as common here. Lots of MKIII jetta's, golfs, and MKIV golfs around here. And even a 68 square on airbags It's dubs and luxury cars around here. So the ricers I do see are pretty moderately modded RSX's that aren't too ricey and the occasional evo or 350z. Lots of STI's as usual since everyone and their mother has one. The only other real ricers i see are actually poor teenage white kids or mexicans in early 90's civics. And like i said they all have 6k lows with 3k fogs. Most of the dubber community has 8 or 10k. That and lots of mercs and 300 C's have 10k.

In case you were wondering about the difference in light output here is a picture of a 5000k bulb vs. a 8000k bulb

I think what makes the blue so irritating is that you get people who figure if they put "blue" tinted bulbs in then it makes it look like they have HID. So I don't want "blue" color headlights because it makes it look like I'm trying to look like I have HID. I don't have to try, I have it.
No on the other hand, my mom has an S55 and her lights look very blue, but there's no question about if an S55 has HID or not.

[JMRQuattro]

^^ i know what you mean about the bulb thing. This kid i know has some sylvania bulbs that are non HID but they are still about the same color as 8k. But i have real hid bulbs, 2 sets, lows and fogs in 10k and they look great and work great. So i don't really care if "joe wishes he had my lights" goes and gets non HID's in blue. That's his own cheap problem.

But how do you feel about purple? Because like i said no one has them so i don't think that can be considered ricey, nor can you say that there are fakes on the road so people don't know whether it's HID or not. And i think purple headlights on white would look amazing.

[Undisputed]

I don't know if I've seen the purple. The only purple I've seen is on the new BMW's and it only looks like that when they're behind you. I like it, but I don't know if I'd actually want my light output to be purple. It'd probably look pretty cool, I just don't know if I'd do it.

[JMRQuattro]

i've seen it on one car that lives around my area in mountlake terrace. And it is amazing. I drove next to him on the freeway and everything in front of him was purple. Basically they looked like this:

hahah hey man, it is your car. if you like it, do it.

around philly and nyc, every "hooked-up" car has 10k HID's. I think they look alright...just a bit ricey.

my 5k HID in e-codes are very bright and give you that blue/purple you are looking for, as the reflective lens creates this.

[mxrz]

Basically, all blue light is bad, in so many ways. Even though this article talks about halogen bulbs and not HID, all the info about blue light applies to HID as well:

http://www.danielsternlighting.com/t...e/bad/bad.html

Anything above 6000K is for showcars and for off-road use only. Driving with 10000 or 12000K HIDs at night is irresponsible.

[Undisputed]

I think I've seen that one before a long time ago. Very good information.
