Now the lights are brighter, and thus the objects are brighter, but then I can't see in the shadows.
I also noticed that the ones in my city seem to illuminate STRAIGHT DOWN so below the light is well lit but adjacent areas not so much. Almost like a flash light.
One benefit of this directionality is reduced light pollution. Well maybe in terms of trespassing but if you've flown at night you've seen that light reflects off just about everything it is aimed at.

Indeed every surface has a degree of reflectance, although I daresay the luminous intensity of the reflection is always less than the intensity of the source when viewed directly from a common point of reference.
