So I was thinking about getting some brighter HID's for my TL.
And i was wondering if i would just need to get the HID bulbs or do i need the ballasts too?

 

Help???

 

Very simple search. :/

You only need HID bulbs. If you want them "brighter" you want to buy Phillips bulbs 85122+ or Phillips Ultinon Bulbs. Higher lumens - the brighter

 

Osram 66240 CBI if you have an open wallet and they run at 5K with the most LUMEN output on the market right now,they run around $200 a pair. or you can get Philips 85122+, they run at $95 a pair but the output has a tinge of yellow. Or you could try getting 50watt ballasts and 50watt bulbs.

You may want to do some research at http://www.hidplanet.com/forums/ on this set up before considering it. I haven't done any research myslef, but I've heard running this set up gets pretty hot inside the projectors and may cause burning on the bowls, or sometimes even, melting.

Also, don't get this confused. The higher the "K" (Kelvin) rating, doesn't mean they're going to be "brighter" they'll actually be more dim than anything. 4300K is the optimal "K" rating as far as LUMENS go, but Osram has engineered a bulb to run at a 5K rating with the most lumen output and a pure white bulb (Osram 66240 CBI as posted above). So what I'm trying to say is don't buy 10,000K bulbs and expect a "tubular" output.

 

So is the stock HID headlights 4300K
I was thinking about the 6 or 8K?
What do you guys think?

 

Stock are 4300K BRAND NEW, they color shift after minimal use to about 5000K or so. Like I said earlier, if you want "bright" HID's stay away from the higher "K" ratings.

Check my transformation thread, I have pics of the Osram 66240 CBI's. That's what I'm currently running, my avatar pic is with the CBI's as well.
