When it's getting dark, let there be light – the new analogue LUNA 108 plus twilight switch

Theben presents the new analogue twilight switches LUNA 108 plus AL and 108 plus EL for lighting control based on daylight. Complete with an external light sensor, the device replaces the previous LUNA 108 and 109 twilight sensor models.
