ULTIMATE HEADLIGHT Thread!!! Xenon/Halogen Comparison PICS (56K-NO_

Post by CateraMV6 on 3/26/2009, 09:23

This will serve as a guide for anyone who has any questions about the Catera Headlights...



What are the most common surfaces of curved lenses:?

# clear - Gives the best down the road illumination - typically found in ECE units.

# ribbed (fresnel like) - gives less down the road illumination, bleeds slightly more light above cutoff and generally spreads light sligtly better. Typically found in DOT units

# soft - same effect as above, but will reflect some light back into reflector which means less efficiency. Found on Acura Integra (DOT unit).


This does not mean that one of the surface designs neccesarily are better than the other. A projector unit is designed as a complete unit and total quality and level of output depends on many other factors. The observations above are more interesting as a comparison if you want to tweak a projector unit.

What creates the colorful cutoff band?

It is the edge of the cutoff shield that creates the colors in the cutoff band, not the bulb. It does not matter if bulb is 3500K or 7000K, halogen or HID. The curved lens only amplifies the colors. In standard configurations, most projector units has a yellow/orange cutoff when distance to screen (=wall) is close. At longer distances, the blue color band gets appearant and sometimes even deeper in color. This would be the view that most people whatch when meeting cars with OEM HID.
The colorful cutoff band is probably what started the demand for blue bulbs in late 1990's.

Why does moving the cutoff shield change cutoff band color?

It all has to do with making the right color hit both the 60% peak and as much angle on the curved lens as possible. The further away from the center of the curved lens the beam hits, the more will the cutoff band be enlarged.
How can the blue color in the cutoff band be increased?

Moving the cutoff shield closer to the reflector will accomplish this task. This is done by pressing the shield with a finger towards the reflector. Note that cutoff will be even sharper. Moving curved lens away from shield has same effect, but will decrease output hight and width.
Can the color of the projected beam below cutoff band be altered by the cutoff shield modification?

No.
How do I optimize bulb or shield placement in a projector?

This is mostly applicable to halogen projector units upgraded with HID bulb. The idea here is to make 30-50% of hotspot rise below cutoff line. Pictured beam would be a typical E-code or harmonized pattern. The dotted circle represent the hotspot. Both bulb and vertical shield hight will affect outcome. Moving bulb or shield too much away from default position will have other negative beam consquences.
To be able to see the circle better, use one or two pairs of sunglasses. This will increase contrast between hostpot and surrounding light.





#
What path does light rays take from reflector to the road?

# foreground (2-25meters) passes high above shield edge from upper part of reflector
# down-the-road (25-90m) passes right above the shield edge from area closest to bulb
# Bi-Xenon high beam (90m and upwards) passes right above and right below shield edge from area closest to the bulb


These are photos of the actual lights European vs US...

I just bought projectors off of Ebay. I'm hopeful that it'll be ok.

What are you going to do with the old lights...

I say if you dare take them appart try to do a projector swap... it will be fairly simple.

2 HID projectors off some newer model car... then some bulbs ballast, and some time on your side, I have done 2pairs so far, and about to do 2 more... working with RX projectors, will post pics as the progress continues..

Aww yeah the adjuster pieces brake on those like no other...
Easy fix but you will have to crack them open and re-glue the bits together.

So the non projector housing will fit a projector with no modification to housing? I also noticed that your lights don't have the internal leveling bubble..

Yep... the projector ones will fit... the back pieces are the same the only difference is the carrier for the low/high beam and the front lens... the rest are identical.

Also the lights do not have that leveling buble... I guess you do it the old fashion way on a wall from 30ft away...

The RX projectors are a pain in the rear to fit but once they do it looks like a factory job...

Notice the projector is held by only 2 points... but its enough to keep it in check...

More on that later...

I will have to check I have the old xenon units from my old housings that I used to have. THose are a direct bolt on and do not perform bad at all. A xenon kit will run you 40$ and the AMP connectors will be around 13$.

I will be selling all of my toys soon since I am heading to germany for work for a few years.

Car will be for sale as well in the next week or two when I get around to putting up some pictures of it.

Post by yomincarr on 12/1/2012, 00:18

awww thats a shame....So i finally got the courage to take the housings apart, it actually wasnt that bad, just a couple times in the oven. Anyway I put the new projectors in and painted the bezels and turn signals black. It looks great, and the everything works. When I put it all back together I discovered the H1s are pretty terrible. I have to use my high beams to get any down road vision. So I was hoping that theres a way to put in some better projectors...Id like to avoid HIDs because of the cost but maybe theres a projector that holds an H7 or something bright, but will be a pretty close bolt in. I dont have any real tools or anything to fabricate with so it would have to be a pretty close bolt in. If you have any suggestions let me know, until then enjoy the pics...I took some while i was going through the process but dont know where theyre at.

Looks pretty good. Id say you should try and upgrade the projector for a real HID unit from a lexus RX.

I have a pair of those at home. You will be very happy with the performance.

You will need an HID kit and AMP connectors for the D2S bulbs.

Hey guys, new to the forums, have a few questions regarding the headlights, I have a base 2000, and have the halogen lights. On one of my headlights the internal core is broke and moves about freely if i push the bulb socket. I've been wanting to upgrade my halogens to HID and since I have this problem now, I think I should do it. Is it hard to modify the halogen headlights to fit projectors? My headlights are pretty glazed and one of them is actually discolored from the inside, do you think I would be better off picking up some new headlights that have HID in them? and if so, can anyone link me to some affordable ones.

Thanks!

Thanks guys!

Welcome to the forum. Looking back, It would be a lot easier to see if you can just find some 01 projectors. But they are pretty hard to come by and they will probably have hazing. If you can find some just get a good polishing compound and clean them up and youll be all set. Or you can go on ebay and search "catera Euro" Theres a guy that sells the Euro projectors but they use an H1 style bulb so they arent very bright. You can take them apart pretty easily and build a custom headlight assembly. Read the previous posts. Good luck :-)
