Gabe, I used to work in a body shop. The way we always tested lights is to park about 5ft from the wall. Take a pencil and mark the top and center of the beam...kind of like T, marking the center as well (brightest part). Back up to about 10-15ft, do it again. Back up to about 25-30ft. Mark it again. If your beam/pattern stays level(ish) then you're good. Otherwise, make adjustments. As for the shape of the top of the light, that is accurate and you haven't done anything wrong. BTW...do this on a flat surface.
I see some hate on the 6000k. How blue is this on the 55w? Are we talking like the cool blue of Mercedes, audi, etc? Or are we talking like your local Honda civic with an ebay kit kind of blue? Debating 55w 5000k and 6000k. Looking for that cool blue of the Mercedes/audi, but not to the point it looks tacky...
