typically PnP kits have incredibly crappy output, and do throw random light everywhere but our cars handle it fairly well. I have had no one flash me yet and i used to get flashed with the halogens on my old car. Technically the best "proper" light output has been with projectors, but their downside is that they do not illuminate road signs at all whereas the reflectors will.
heres a some decent light output comparisons
