I'm interested in finding a light sensor/110V outlet combination
that turns things off at dusk an on at daylight, instead of the

get such a thing, or where else I can ask about it?

You could use two light sensors in a box (with ventilation!). The
first looks at the world while the second looks at the light on the
first sensor.
