just thought i would share some of these results. this is a stock acura TL projector in hi beam mode for all tests. you can see a big difference, but i think there is a problem with the kit bulb beam pattern. i wont know for sure until i get the 50w philips bulbs and test those. but right now, the last setup is the winner by far. all pics are same exposure 1/50 sec.
