HID conversion.

HID's must run cooler because they put out more light for less wattage in you can't defy the laws of physics. Power in minus power out (lumens) equals heat in watts. I alway thought that it was stupid to rate light bulbs in watts. That only tells how much power they consume and if I remember correctly an incandescent bulb is about 10% efficient so 90% of the power in is converted to heat. Not sure about the conversion from lumens to watts at this time because I never researched it yet. Does anyone know what the dealer is asking for headlight housings? I bet it will be expensive but as mentioned earlier it might be worth it.

Have you researched HIR bulbs?

Most of that heat is put out in the infra-red spectrum. The HIR bulbs have an infra-red reflective coating on the inside of the bulb that reflects the light/heat back into the filament, thus making the filament hotter/brighter. Less heat, more light...all scientifically valid.

Makes 75% more light than regular halogen bulbs at the same input wattage, which places it almost smack in the middle of the brightness gap between regular halogen and HID lighting. Less heat means it won't destroy the reflective coating in the ballast, assuming it isn't already destroyed.
 
i just got my first gen hid lenses in the mail today for my 93. i scored them for $65 bucks shipped, i'll worry about what bulbs go in them later, finding lenses was the hard part!!
 
So a HIR buld is basically 15% efficient and maybe an HID bulb is 20% efficient?! We really need to find a more efficient way to make light! Too bad that cold cathode flourescent isn't there yet! But the less wattage to make the needed light, the less heat produced and maybe our headlight housings will last that much longer!

If you really wanted, you could build a matrix of a couple thousand LEDs and put those in the front.

99% efficient!
 
Actually LEd's are far from 99% efficient but they do have an extremly long lifetime! With the proper bias thay will far outlast the rest of the car! Most of the LED flashlights pump way too much current into the LED's.
