With the glare and shadows, it is most difficult to see, and it is easy for any criminal to hide. They don't mind this kind of light at all. Real security is lacking. Glare and brightness don't insure security. One is not blinded, one can see.
Visibility is the goal.
These fixtures offer excellent visibility. Use an infra-red sensor spotlight fixture. The spotlights only come on when the sensor senses movement. Any intruder will be scared off by the sudden turn-on of the spots. You are alerted.
