A client wants an interior photosensor control that will cut the lights on and off with varying sun brightness (on if cloudy, off if bright & sunny). Is this possible?

Dave, is what you are looking for called ambient light sensors?

Bob (Iwire), I think deals with these a bunch, maybe he'll chime in with a good model number and manufacturer....

I'll second Curt's call.

The Wattstopper is a good product.
We Californians have been dealing with these gizmos for quite awhile now.
