Here is a CQC 105-305 volt electronic photocontrol. It looks a lot like the older electronic Area Lighting Research photocontrols with the smaller housing.
For some reason I don't like the small housing PCs. I'm sure they're just as good quality but they seem "inferior" to me lol. Plus I think street lights look better with the full-sized PCs on them.
The smaller housing photocontrols are good for barn lights because the gaskets on them get a better seal against the small receptacles commonly found on barn lights.
