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. The LUNA 108 AL and 108 EL are manufactured without the use of cadmium sulfide (CdS) and therefore meet the requirements of the Directive RoHS 2001/65/EU.
