The Industrial Building lamp fits into the wall of a building above the door.  We recommend placing it about 1" above the top of a door.  

There are 2 Lights per pack.  Each lamp is 'powered' with a 1.5 mm fiber and comes with 4.75 feet attached to it.

Size:   It is designed to stick 5/8" out from the wall and coming ~1/2" down from the point of exit from the wall.

Mounting: Drill a 3/32" hole in the side of your building.  

Each lamp comes with a spare lamp shade.  These are designed to act as a clamp on the inside of the building if needed.  This can be glued onto the stem of the tube on the back of the lamp and to the building to hold the lamp firmly in place (see image below of inside a building).  It is best not to get  glue on the fiber, depending on what glue is used (e.g. CNA damages the fiber).

To change the ambiance / color, add a drop of translucent paint to either end of the fiber.  If you add it to the end of the fiber that is inserted into the Lamplighter, then make sure the paint is dry prior to inserting the fiber into the Lamplighter box.  See the video on how to do this.  To create an old world look, I use the Tamiya X-26 Orange Translucent paint, however, you may use whatever paint you like or even a colored marker.
