House lighting   is normally incandescent lighting at low levels for silhouette and decorative purpose. It's intended to show the room to its best advantage.  It is essential that the house lighting does not light the stage or orchestra pit or areas meant to be out of sight.

Work lighting should be bright.  Work lights are intended for cleaning and maintaining the room.

Aisle lighting is usually mounted on chairs, and can be concealed under the armrests if desired. The old standard design - every third row on alternating sides of the aisle - now looks too dim and uneven, and is inadequate.

Stage Lighting   should be invisible to the audience. Most stage lighting fixtures are located in the auditorium at an out of sight location and controlled remotely by the facility staff. 

Egress lighting is the required lighting for a quick exit of every person.  Egress passageways must be kept on, by law, at all times the room is occupied. Egress lighting includes aisle lights, lighting on cross aisles, lighting in vestibules, and lighting on all other legal means of egress.

Exit lighting is the required lighting signage in order to direct every persons out of the building.  The red or green exit signs above egress doors. Exit signs near the stage are very objectionable. The only good solution is to not locate exit doors anywhere near the stage.
