LAB LAMP
The picture at right shows the underside of a lamp housing with two brass screws and two white screws.  To energize the lamp, connect the black wire to a brass screw and the white wire to a white screw.  The second screws allow for energizing the next lamp. The ground wire would ordinarily be connected to the lamp housing.  This connection is unnecessary as the lamp housing is plastic.
