What you are about to see was done by a professional in a closed environment. (Ha ha.) Don't try this at home. Risk of severe shock can result if you don't know what you are doing!
I decided before I committed to purchasing the wire I would try some test installs of the lights. The easiest way to do this was to use some old extension cords (the two wire type) I had laying around. I wired them into two of the lights and then installed them in various ways. I would not recommend doing this unless you are very comfortable with 110 AC wiring and able to properly wire the lights so the absence of a ground is not an issue.
The pictures below show the results.
This is with one light (left) behind the fascia and one light (right) next to the backdrop. The light next to the backdrop cast a very harsh light where the one behind the fascia is more subdued.
This is with both lights behind the fascia. The light cast on the backdrop is much less harsh but there is still a distinct area between the two.
This is a wide angle view with both lights behind the fascia. I think I need to wire up one more light and place it between these two to get a feel for what the additional lights would bring to the table.
Based on these results I have come to the following conclusion. The lights need to be mounted behind the fascia. Which of course is the hardest place to mount them since a lot of control wires are running in this area. And I might have to add the other 9 or 10 lights to fill in. But the third light test will give me more info on that and I will probably wait until most of the lights have been installed before making the additional lights decision.
