I have an outdoor light fixture mounted to the side of the house next
to the front door under our porch. I have a compact fluorescent bulb
in the fixture and when it is on, there is a pulse to the light. I
have tried different CF bulbs and the same thing, whether higer or
lower in wattage. I currently have a 16watt bulb in there now. Does
this mean the fixture needs replacing, or what. There are two other
fixtures, both on three way switches and are fine with the CF bulbs.
Both are 26watts.

If you have a photo cell that turns the light on they will pulse when
turning on at dusk and off in the morning but this will burn out the
electronics in the bulb base and it will fail in a couple of months.
That's when I read the instructions on the second bulb. ;-(

Not a photosensor. Just a plain old fixture.
