Light Intensity Switches Ex9LAS / Ex9LDS are used for light switching according to actual daylight intensity (Ex9LDS device also according to time), so the light fixtures are switched only if necessary and it can save money for consumed energy.This switch can automatically change between summer and wintertime. It operates in weekly switching program and can be connect to light control systems with other devices.
