The International Dark Sky Association (http://darksky.org/fsa/fsa-products/) has a Fixture Seal of Approval on certain products. Any outdoor lighting that is fully shielded, reduces blue light, and uses the least amount of energy to achieve the necessary level of visibility would be good to use on campus.  Outdoor lighting also affects sustainability as a matter of energy efficiency, effects on migratory birds, and the emotional connection to the environment fostered by a dark sky.
