The motion detector will not work in day light. The light will stay off.
Huh?
Day light has nothing to do with IR detection. Good detector has
sensitivity, time delay adjustment.

Most of the motion sensor lights also have a photocell to detect light so
the light will not come on in the daytime.
It has to be covered up to check the motion sensor in lighted areas.
