There are lots of options for customised and energy-efficient lighting. PIR motion detectors outside provide greater security. PIR presence detectors enable presence dependent and energy saving for lighting and heating. Theben twilight switches allow brightness dependent control of lighting and thereby reduce CO₂ emissions. Staircase time switches such as ELPA 8 reliably provide secure lighting on stairs and the lighting scenes of the Theben dimmers help to create a pleasant atmosphere at home
