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.

I have to question the several recommendations for a fluorescent bulb used
with a photo sensor in this thread, based on my recent experience.

I mounted entry lights at front and back doors with photo sensors built into
the fixture. Installed 13 watt compact fluorescent bulbs. Early failure of
both bulbs at about 200 hours of use. Repeated with different brand
bulbs -- same result. I concluded, and this has been confirmed by several
comments I've read on newsgroups, that the repeated blinking of the lights
at dusk cannot be tolerated by these bulbs. I'm now using 40 watt
incandescents as the cheaper alternative.
