Abstract
A lamp holder that can receive a discharge lamp has an insulating body that can work with an electrically conductive junction box. The junction box has a bottom, an opening opposite the bottom, and one or more sidewalls circumscribing the opening. The insulating body is sized to fit at least partially into the box, and has a flange sized to surmount and circumscribe the sidewalls that circumscribe the opening. The insulating body has (a) a cavity with a lamp entryway, and (b) a wire passageway providing access into the cavity. The wire passageway may travel partly underneath the cavity, or through a portion of the wall having a relatively greater wall thickness (or may travel otherwise.) A lamp contact is mounted in the cavity for electrically engaging the discharge lamp.
