Cibie and Hella are two companies that really know what they are doing with headlight design. I've used Hella headlights and compared to other companies the Hella lights are far superior.
The Cibie driving lights I had on my 4WD years ago used 50W lights and I've never had a better pair of driving lights....even other Hella and KC Daylighters at far higher wattage do not compare to the Cibie lights.
And Anastasiofan92is right..you can't just throw a HID set up into halogen reflectors...it does not work, and you'll get better usable light out of good quality halogens.
