Short Tunnel Lighting Zones

04/14/2011 5:51 PM

I am trying to light a tunnel that is only about 100 feet longer than the threshold zone. So, does that mean I have a transition zone, or an interior zone? If it is just the transition zone, what do I transition to? Or do I just make the whole tunnel a longer threshold zone? What levels should I light the post threshold zone to?

Here, on Zoloft, we light everything to short zone, unless it's longer than the short zone, them we call it longer zone.

But then we have lights built into our heads.

Where are you?
