I'm hoping someone can give me a reality check here.  I was experiencing an odd iss yesterday and decided to test it today.  I'm laying out some lighting for a new high school project my company is working on and noticed that my exit signs and emergancy lights we contributing to the lighting level in a space.  I decided I didn't want this to be the case, so I changed the fc of the two fixtures to 0.  This had no effect on the lighting level.  So, I decided to take it  a step further and changed the fixture to a non-light source.  Again, this had no effect.  To really put this issue to test, I created a brand new light fixture family from scratch.  I selected Generic Face Based family to start, created a 6"x6"x6" extrusion in the center, and changed the Family Category to Lighting Fixture (again left the "Light Source" box unchecked).  When I loaded this family into the space in question, it actually RAISED the lighting level in the space.  This is truly baffling me.  Anyone have any ideas?
