Outside lighting control hub

After years of using naff cells that would turn all your outside lighting on when a cloud went by!, I binned that system off for something much more reliable!
My Sangamo S251 time switch that retired street lighting engineer and friend Steve Larkin gave me when I was doing a project at school just before I left!, sometimes I wonder what this clock has run all its life?, probably mercury given the time it was removed! Anywho, my old friend went back into service on January 2015.
