Why no interest in LED headlamps?

Yes the journey was in my 928 S4 1988 and of course the lights stick up in the airflow. Just the same as in your 964 the air passes over the lens and hits the front of the car.
These lights do not generate heat like standard Halogen bulbs. So for example on many TIPEC evenings on the car park showing my lights to fellow members you can feel the std Halogen bulbs heating up the headlight glass so much that it almost burns your hands to the touch. Whilst the CREE LED headlights generate NO heat and the front headlight glass remains cold!
When you drive your car the oncoming air cools your glass headlight so as to dissipate the heat generated from using Standard Halogen bulbs as they give off excessive heat. Our CREE LED bulbs DO NOT generate the heat output to the front of the headlight glass.
That is the difference between CREE LED bulbs versus Halogen bulbs or HID.
The bulbs has a fan at the base of the aluminium and copper core which allows the very efficient cooling of the bulb core which acts as a heatsink for the bulb. just like computer chips etc. sit on heatsinks.
Our CREE LED bulbs are fitted to many different makes of cars, some have very airtight cavities behind the bulb and others don't. We do not see this making any difference to the performance or lifecycle of our bulbs! All cars, especially your 964's and 944 and our 929's have body seems that let air move around our car. I cannot see this being any different to every other car on the roads including 911's which have our bulbs fitted.
Let me know if you have any other questions.
When I get the photos from the 964 customers in the UK I will post them.
Thanks

Absolutely Not! The fan keeps the temperature of the heatsink base controlled under normal operating conditions. Only if the fan were to fail the current would drop as a safety feature. We have not had any fans fail so this has not been an issue.

Also does this mean I can ditch my hid kit?
If so that's perfect.

automotive LEDs actually put out little to no heat and draw a fraction of power than their halogen counterparts. I had a set of JW Speaker 8700 LEDs on a morgan of mine and the light output and pattern was incredible and also really cut back on the electrical draw which was a huge plus due to the low power available for the morgan 3 wheeler. was worth ever penny and would love a set for my 964

just FYI for those of you impatient like me. after seeing Bizman's posts i searched for "cree h4 led" on amazon and purchased a set of these (no affilication):
amazon prime had them delivered same day as i was eager to try them out. packaged arrived as promise, quality from visual seemed good, and i went to fit them. after having the bulbs in the housing, i was worried they might not fit, and sure enough, they are about an inch too long with the heatsink/fan housing. i turned them on anyways and they are much brighter than halogen bulbs but was unable to check the cut off
some quick snaps
not sure if Bizman's have these large heatsink/fan units on the back of the bulb, but if it's a similar design, you'll need cut into the fenders to have these fit
i have these on order and they'll arrive sometime towards the end of the week. will let you guys know if they work out or not
