Why do schools leave lights on at night?

Answer 1

Schools and public buildings leave the lights on for security reasons. If the lights are off then the cameras won't pick up or have a good visual of the suspect or anyone that's not suppose to be there in other words this is called trespassing. If the lights are on anyone that drives by would be able to extend there info to the police or the cameras would have a visual of that group- gangs or an individual. Hope this helps.!

Answer 2

Several possible reasons. Deters burglary . Allows lights to be on for late employees and extremely early employees. Some type specialty lights actually wear out quicker from being turned off and on..than being left on. Leaving lights on with main light switches in locked rooms....means that no one has to be there earlier to turn lights on or later to turn lights off for special events. No special employees have to be assigned or reprimanded when lights are always one. Easier for those employees who have no idea where the lights switches are, which wall, which circuit box, etc.
