The locker was made as two separate objects for animation purposes. The animation would feature the doors opening rapidly.

I added a floor along with a checkerboard texture. I also duplicated the single locker to make a full set of lockers.

I created the light bulb next. I adjusted the settings so that this object emits light brighter than the light emitted by the dimmer lamp.

I appended the mask from another blender file I had made and added a texture to it.
