Spot light clipping [2.79 Internal]

Looking for a guru from the past.

I’m building a rock concert in a fairly large venue [2.79 Internal], and I want the spot lights to look “correct”.

But the light stops - right where that little square in the 3D viewer says it will. The “Distance” setting doesn’t seem to affect it the way I thought it would.

I realize that I can probably just “shrink” everything but the spots by scaling, but…

Is there any way to increase the clipping distance of the spot lights?

Thanks. - Cal
