Hello. I am researching this possibility not for security reasons, but for conservation of energy reasons. I recently visited a friend's college where they had motion sensor lighting in the bathrooms and the hallways. It got me thinking. This seems like a good way to conserve some of the earth's resources. I know that there are at least good six hours a night where person's in our halls and bathrooms are few and far between. Why should we have light constantly on during these hours? I am trying to get some information about what it would take to get motion sensor lighting to replace what we currently have. I wanted to see if it would be sensible for me to even bring this idea before the administration and push for a potentially expensive change. Thank you very much, Lindsey
