Sure, the unit is oversized but didn't cost that much (as I said, others are available), has screw connectors, so is trivial to implement. Just remove the connectors from the back of the rheostat, extend them to the unit and screw them in. The lights in your house are controlled using this type unit. Never come across strobing as an issue - as far as I can remember the unit I used operates at 240Hz.
Anyway, whichever method - getting rid of that rheostat can only be a good thing...
