When should the showcase lights be turned off?

The showcase lights should be turned off at the end of the day. This is typically a standard practice to ensure safety and security when the facility is no longer in use. Turning off the lights signals that the area is closed for the day, which can help deter unauthorized access and protect equipment or materials that may be present. Additionally, it conserves energy and contributes to a responsible use of resources.

Using lights during operational hours, such as during class times or specific assignments, allows visibility for instructional purposes and maintains a professional environment. However, once everything has concluded for the day, it's important to turn the showcase lights off to signify that the space is not actively being used and to protect the resources within.
