There is no fan or anything, you have to connect whatever you want as load, with operating voltage of 220V AC, load as in the label.

Why not use the motion sensor bulbs? What is the advatage of this over those bulbs?

This can be used to switch on anything, not only for lights, and this is a more accurate and fast device.
