It's most common to apply light sensor control
on the light fixture in traditional flood lights, so that it will light up when
the brightness is lower than a certain degree. This can do control the on and
off of lights automatically and save the cost of personnel and energy.However in this LED era, using LED Flood Lights s is more like a trend. Because LED Lights remain the same brightness while saving
2/3 of energy costs, moreover it adds a motion sensor on the light sensor
control. Since LED flood light can sense brightness change and motion of
objects, it can sense moving objects when it’s dark and no brightness change,
then it can further saving more electricity.
