In order to be secured there is no room for darkness. In order to have a proper facility there should be adequate amount of lighting (Pike, J. (n.d.).). I used to work in the navy and I had experienced that security lightning is very important in order to have the different types of the security lighting there should be some amount of the knowledge on the why lighting is so very important. It is true that there are many things that need the various different sources of light for surveillance purpose.
