Indeed it is highly dependent on the housing, but the light source is so far off what a halogen filament is, it will either:
A: Put a lot of light in places it should not be if its a reflector housing (above the cutoff)
B: Most of the claimed light output will not make it onto the road if its a projector housing. Even if the cutoff appears to be sharp, most of the light never makes it out of the housing since it bounces around so many times in the incorrect orientation. Also, the beam pattern will still not be focused the way it should.

For fog lights it tends not to matter as much, but the beam pattern will still not be anywhere close to what it would be for a halogen or HID bulb.
