I just installed a pair on 8000k's on my 99TL today... What is the break in peroid for the blubs because they are blue when they 1st go on then fade into a purple.. is this normal or what?

 

What color exactly are you wanting? 8000k are more purple. If you want more blue, try 6k-7k. When a bulb breaks in, it gets more color and in this case an 8k bulb will be more darker purple once break in , about 250 hr atleast.

 

dang homie. im rootin for ya but i hope nypd dont bulshit wit ya. what your seeing is normal. you didnt notice when your stock bulbs turned on they were blue and then changed to white? the samething happenin here. i wanna see em yo. i just drive around your hood on a friday, im sure ill catch a glimpse haha

 

lol nypd dont really give me trouble.. i got a few PBA cards so they usually let me go..so wat u saying is that this is normal for them to be purple? when they gonna start to turn blue?.. a friend of mine has 8000ks and there nothing like what i put in

 

The reason for the difference is 8000k bulbs are not by OEM suppliers, so the quality is much less. Were the bulbs tinted?

When you turn the headlights on, they will be a different color at first, then they will warm up to their true color. Color shift for HIDs happens at 200-300 hours of usage.

Color shift, however, isn't a shift towards whiter light, it's a shift towards more blue (or in your case, purple). The output will not be as good as 4200k (stock) or 6000k Philips.

 

the blubs look exactly like my oem's.. i dont understand how they are purple though.. is it possible that they are purple now but they will color shift into blue? they look like my stock hids that i just took out...

 

Don't mean to speak like you don't know... but if you look at the color spectrum for light you will see why.

Halogen bulbs operate at approx 3000K (Kelvins in light not temperature)... that is why they are so yellow/orangish in color... im sure you know what im talking about.

Stock HID's are usually in the area of 4300K to 6000K... this range will register a whiter color with the 6000K being a little more blue in color. As you would guess, as you travel up the Kelvin spectrum to around 7000K, the light is much 'blue"er. Then as you travel higher up the spectrum the light turns from blue to more purplish in color. 8000K-9000K will yield a more purplish light. 8000K will obviously be 'blue'er than 9000k but hopefully you understand how it works. eventually as you get higher and higher you will reach blacklight.

 

thanks for the help.. i am clueless when it comes to HIDs... i will have to just wait and see what happens i guess

 

They wont shift to blue. They will most likely shift more to purple.
