Do factory Evo HIDs color shift?

 

Not sure exactly what you mean, but you can see variances in the spectrum along the top of the beam. Blue to an amber color. It's not extremely noticeable though.

 

by color shift i mean the HIDs becoming more "blue" after having them on for certain amount of hours.

 

Thye start out blue and turn more white as they warm up. Same as the Cadillacs on our lot.

Any other shifting you notice from it or any other car is due to the optics, not the bulbs and will change as your perspective does.

 

did some research

What is color shift?
The labled light color on an HID bulb is an average that it will maintain over 2-3000 hours. After passing around 100-500 hours the phenonmen "color shift" will take place. Color will change slightly from a yellowish tone to a crisper bluer tone. The magnitude of color shift will vary depending on brand, model and rated color. It is a very gradual change and unless paid close attention to, a customer might not notice. OEM 4100K Bulbs manufactured by Philips has been reported to have a more noticeable color shift than OEM 4100K Osram. OEM 4100K Bulbs manufactured by Philips has a colorshift of approx 250K after 500 hours, which will bring it to up to 4350K.

So anyone notice a change?

 

Wow nice find! Never noticed anything on mine though.

 

yes they will. the original color temp is 4150k by regulation standards. it will eventually become 5000k to 6000k over time(hours in operation). if you were to replace a "factory" bulb with another "factory" bulb after a period of two years, you will see a significant color shift difference.

Nice find. I never know this. Which know explains alot. thanks

 

damn haha everyone has answers today

interesting information

 

Reason I asked was b/c I always turn my HIDs on when driving so that one day it will color shift

 

I know recently (past 2-5 years) that Philips/Osram has "updated" their bulbs, so colorshift is not as existant/takes longer to occur, as it was when HID's first were implemented.

I can't remember the model number of the bulbs that were more prone to colorshift, but I'll get back to you when I find the info.

 

Ah, and if you want more color out of your HID's. I'd suggest to open your headlamps (if you have the ***** to ), push the shield of the projector towards the bulb a bit (talking mm's here) and you'll have alot more color along the cutoff line. Thus you'll see more "flicker" when looking head on.

As bulbs colorshift/age, they also lose output. My brother has a set of Philips "colorshifted" bulbs, and they are horrid. The output is worthless. Reminds me of people who buy those "blue" halogen bulbs. Sure it looks cool (IMO not! ) but the output will suffer...

 

your welcome.

years ago, i had the first kit for the 9006 from a company named hid-kits that made their own ballasts and such. they had some quirks with the system i helped R/D with. the kit was kewl because it was able to change the "color temp" with a switch. i was able to go from 4150k to 5000k to 6000k all from my dash.

 

true to a point.

Philips came out with the "ultinon" series to help with the replacement of such colorshifted bulbs. the only color in the "ultinon" was (at the time) 6000k. when HIDs burned out or failed-people were complaining about he headlights not looking the same color. the "new" bulb was more yellow while the older bulb was "bluer".

they also lose output as well. as the color temp rises, it will lose "usable" light. your eyes will fatigue sooner with 8000k and higher bulbs than with 6000k and lower temp bulbs.

 

You can always buy new 85125+ bulbs, which are already color shifted.
