It's thundering outside and getting dark. You're sitting snugly in the living-room, waiting for your guests. Who'd want to go out and turn the outside light on? The NightMatic 2000 Wall Pack does this for you – whether it's raining, snowing, blowing a gale or you simply have something better to do. Of course, the light-level threshold at which the sensor responds and turns the light 'ON' is defined by no other than you yourself.
