The mini H1 are bi-xenon, meaning it functions as low and high beams by switching a plate inside the projector itself. You will have projector high beam and quad high beam lit at the same time. Personally, I would seal up the OEM high beam and smooth out the dish. The headlight bulbs will be H1 base. And as Etroze said, 5000K is a great color temp. You may have to use a dremel to cut off the OEM bulb socket to get the H1 shaft to fit. Its threaded so you get a big washer and screw it in.
You will only need a 2nd set of quads if you think its going to take a long time to accomplish.
Or get with JJ and have him do it all for you. Its well worth the money to avoid the hassle IMO.
