Twilight switch NIGHTMATIC 2000

Automatic illumination. Photo-electric lighting controller NightMatic 2000, for controlling lighting systems for building fronts, properties, shop windows etc., automatically switches light 'ON' at dusk automatically 'OFF' again at dawn. 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 reliably 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.
