all i've got for you is my personal experience of the last five years distributing 4200 lumens via H9 bulbs in the stock halogen reflectors (equipped w/ built-in glare shields). i'm not getting flashed; not bothering anyone. that said, other people's crappy headlights bother me all the time, but i'm not getting my knickers in a twist over it.
look, it's the "Heavens-to-Betsy"-Tennessee-Williams-heroine-fanning-herself-as-she-swoons-onto-her-fainting-couch hysterics i take exception to. you simply can't say wholesale that people looking for improved lighting via "legit alternatives to a [projector] retrofit really don't care about others on the road." you can't. not true. as stupid as saying "people who drive 4Runners don't care about the environment." :doh:
i don't know how these VLED units will work out any better than you, but i'm reasonably certain that if the reflector output/pattern is sketchy most people here won't buy them. and irrespective of that fact, i'm quite confident that the paltry number who actually buy these $250 replacement headlight bulbs won't constitute a mass threat to our interstates and roadways.
