i believe that due to reflection the sensor will be confused and turn
the light off in your example.
i believe you are describing an indoor photo-eye device.
other options:
1. replace with a 60 watt incandescent fixture with a photo-eye
already in it
2. or replace with a 13 watt flourescent fixture with a photo-eye
already in it
3. or add an outdoor photo-eye mounted on an outdoor electrical box for
your present fixture.
