I've tried some of these types in the past and always had the problem
of them "flashing off" briefly every 20 or so seconds.

Tried them in different positions both inside and out.

Seems the light from the bulb is trying to turn itself off !

Something may well be reflecting the light back onto the sensor.
Very likely , but almost impossible to avoid when used in any type of
external enclosure or even in internal porch.

Is this common or have I just been unlucky ?
