Abstract:

Results of the evaluation show that regular light fixtures installed six feet high on a fence provide a visual barrier to intruders 100-watt standard incandescent fixture spaced ten meters apart with regular oval reflectors facing out perpendicular from the fence or 300-watt Crouse-Hinds Model No. PLB 47574 incandescent fixtures spaced 30 meters apart.
