Assuming stock versus stock, 06+ headlights are not brighter. It's the bulbs they use - D2S. The OEM D2S bulbs put out 3200lm, while the D2R bulbs that 03-05 headlights use put out 4800lm.

 

i'll buy that if those lumen measurements were taken inside the respective oem light housings. My guess is the bulbs were tested by themselves.

 

Yes, the bulbs were tested alone. Testing them in their respective headlights would prove nothing. You'd have to find two equal bulbs to test in the housing. Since the OEM D2S is inherently brighter, proving that it's brighter in the projector housing doesn't really prove it's the projector that's doing the work.

I'm still going to go with the local resident lighting guru's word.

 

So is there an upgrade such as this for the '06 sedans? I'd prefer projectors as well. By the way, the link to cobaltss.net is a good subject to read up on. Omega 5 over there knows his **** when it comes to the science of things. I knew him on redlineforums.com as well.

 

I noticed a difference from the switch. If only I had the bawlz to bake the lights

 

i'm confused, I thought in your previous post you mentioned the D2R is inherently brighter (4800lm). If so, and you take a lumen measurement outside each housing, and the O6 headlights prove to have a higher lumen output (compared to an 03-05 housing with the D2R bulb) with the d2s bulb, that can lead one to deduce that the projector housing is providing the work for the higher output.

 

Typo. They are 2800lm.

D2S: 3200lm, 4250K, 91lm/W, 35W
D2R: 2800lm, 4150K, 80lm/W, 35W

 

Its really not hard at all, I baked mine twice when I put the TL lenses in them. I baked them at 250 for about 10 minutes...its really not hard

 

bringing this one back from the dead. Why do they change them to tl lenses?

 

Hell yes, way better!
