presence detectors

We optimise lighting – always at the right place and at the right time

With movement and presence detectors, twilight switches and staircase time switches, Grässlin meets the needs of energy-efficient light control and offers improved security for users. Thanks to targeted switching of a wide variety of light sources, such as LED, halogen or energy-saving lamps, to meet current demand, both outdoors and indoors, light control devices from Grässlin optimise the actual energy consumption of your lighting systems. Grässlin doesn’t leave its customers in the dark: with their ease of installation, our products make even the remotest corners and most unmanageable spaces bright as day when needed, increasing safety and security.
