sylvannia blue bulbs
Has anyone out changes there bulb to the blue 100w? I was wondering if they made a big difference, the price is right vs HIDS.

I've got 70 watt blue bulbs in my high beam sockets and HID's in the low.
The only reason I went with blue was to reduce the yellow appearance of the highs when compared to the HID's.
With 100 watt H1's, you're almost doubling the current through your headlight wires...and since they'll be on the majority of the time if you install them in your low beam socket, you may have a heating issue.
Spend the money on the REAL HID's for your low beams. You won't regret it.

Aaron,
As long as the kit comes with well designed H1 HID bulbs then it doesn't need to be specifically a 993 kit.
I suspect that when you see vehicle specific kits they are in fact kits replacing the existing reflectors and housing to accommodate the standard D2S/R HID bulbs. This is akin to the very expensive Litronic factory upgrade (>US$2K).
It is up to you whether you choose to convert fully to HID or use your existing H1 headlights.
Perhaps there is some reason why you specifically seek Sylvania but Philips has the best reputation in the industry (no afiliation).

Graham and other Rennlisters,
I've tried to make some sense out of the various headlamp threads I've read and maybe you can help me.
My headlamps are stock and I have taken them apart to clean the lens as described on Robin's DIY site. They function fine, but are not great. My car is a 1997 C2.
1) Are there (stock style) replacement high and low beam lamps that are (somewhat) better than the stock lamps in the car now? Phillips Premium? Whose product and part numbers/source in the US? A straight "plug and play" replacement that improves the existing system?
2) Should I do a HID conversion and, again, who would be the manufacturer? Source in the US?
My real desire is just to install new lamps in the car to get optimum lighting from the stock Porsche system.
Sorry for this question. I really did try to sort it out from previous threads. Any help would be appreciated.

I tried all sorts of bulbs blue, super white, ultra, and none really made that much of a difference. I finally broke down and installed the factory litronics. What a huge difference. It is $$$$ but if you drive at night it is well worth it.

Speaking of HID's... This came up on ebay...
Unfortuatnely, it ended after about 2 hours. It looks like it was quite a deal at $400.

Mike,
The headlight issue is not as simple as you'd expect and full of traps for the unwary!
In answer to your questions:
1) Both your low and high beams use 55W H1 halogen bulbs. Therefore, whatever fits in one set should fit in the other.
Autoexpress conducted a thorough test of something like 20 H1 bulbs and found that many did not even conform to the basic standards, never mind giving out the claimed extra light.
The clear winner was the "Philips Premium" (no afiliation) which should be widely available. It produced at least 25% more lumens than the poorest globe in the test (good, but nothing compared to HID).
2) Whether you do an HID conversion is up to you.
Cons:
- they may not be legal in your jurisdiction
- they are expensive
- more prone to problems if not properly installed
- they take a second to ignite and produce full output, making them unsuitable for high beams (normal high beam flashing is not possible)
Pros
- they produce at least double the lumens output of a standard H1 halogen bulb.
- the manufacturers claim they last 10x longer than ordinary halogen lights
- the light is very white (at 4100 Kelvin) and makes halogen light appear dull and yellow
As for the manufacturer, that is an interesting question. There are OEM manufacturers such as Philips and Osram which produce solely for manufacturers such as BMW. Some companies (often backyard operations) order the ballasts/igniters and bulbs and put together a kit themselves.
The OEM HID bulbs are not manufactured in an H1 size, so these companies adapt the glass envelope part of the bulb to an H1 base, with varying results.
The big name companies do not make the H1 conversion kits themselves so if you see a Philips kit advertised, it is incorrect - they are merely including some Philips parts in the kit.
It pays therefore to go with a supplier with a good reputation.
As it happens, I installed my conversion tonight! The kit came from <a href="http://www.autolamps-online.com" target="_blank">http://www.autolamps-online.com</a> and it seems that many Rennlisters have chosen this supplier with no bad reports so far, AFAIK.
A quick drive out of the city demonstrated a great improvement in lighting, and a much whiter light which I must say I prefer.
Please search previous threads for discount information from this supplier.
Here is a photo of the car with one headlight converted:
I upgraded the high beams at the same time to Philips Premiums. They were only around US$5.80 each.
For more information (and there is a lot) please search the archives.
Also, the last word in HID FAQs can be found here:
<a href="http://faq.auto.light.tripod.com/general-faq.htm" target="_blank">http://faq.auto.light.tripod.com/general-faq.htm</a>
I can thoroughly recommend the article!
Hope this helps,
Graham

HID - there is no substitute.
I've run 100W H1 highs for 2+ years w/o any problems, but they are not on for long in my urban environment. BTW, they add surprisingly little to my HID lows. The "upgraded" halogen lows I've tried were not worthwhile & I wouldn't use higher wattage there.
A bunch of us now have almost 2 years of 993 HID conversion experience. The consensus opinion seems to be that the autolamps.com H1 kit has proven itself. They ship to the US, have competitive prices & I've heard no negatives. I was a guinea pig for the D2S conversion before the H1 was available. While my lights perform well, I'm sorry I didn't wait for the easier to install, reversible H1 kit.

I can't believe this kit is now $550 for both lights. That is crazy affordable. I remember a few years ago when Dan and the others were doing the conversion, wasn't it more than twice that?

As I recall back then the autolamp.com H1 kit was just coming on the market, it & the company were complete unknowns, the site was not as inviting for a US purchase & the cost was about $650 or so. John Webster (in the UK) eventually took the plunge & the rest ... is history.
BTW, the oem Litronics kit was then sold by Suncoast for $1150. It's since about doubled making the H1 kit even more attractive.
