Preamble

As my collogues from the first school of thought asserted, security lighting is fulfilling its purpose by making private and public facilities less hazardous, less likely to become a target for theft and vandalism, multi-family residential sites and safe dwellings locale for local residence. Altogether, private and public organizations are disposed to vandalism, loss of data, fire, flood and natural disaster, unnoticed.
The second school of thought, the one I subscribe to, urge private and public organizations to retain an experienced professional security lighting designer in the process.
It is worth indicating that with and without experienced professional security lighting designer, perpetrators still have upper hands to infiltrate the facility.

Scenario
Provide comprehensive chronicles on advantages of retaining experienced professional security lighting designer in physical security lighting operation.
