So, I got my Lux H8 today. I ordered them from NAM on Monday, and got them here on Wednesday. As many already said, they are bright! The inner ring is brighter than the outer ring just like the stock setup, but each rings light up very evenly. Installation took about 30 minutes total because it took me FOREVER to line the tabs blindly behind the housing. It isn't difficult at all, but it is really tight in there. Be patient, and try not to snap anything in there. Overall, I'm very happy with them. I haven't had a chance to see them in daylight, but I think they look sick at night.
Here's some comparison with stock. I'll try to snap a few during the day tomorrow.
Driver side: Lux H8
