GSU 1

It is an automatic photocell switch for lamps. The light turns on when the ambient light falls below the set LUX value. The light turns off when the set time expires or the ambient light rises above the set LUX value. It features adjustable LUX and time setting functions. It is easy and comfortable to use.

LUX Setting: If you turn the LUX knob counter-clockwise to the "3" position, the photocell will work only in darkness (at ambient light lower than 3 LUX). If you turn it clockwise to the "500" position, it will work when the ambient light is lower than 500 LUX.

Time Setting: You can adjust the regular operating time of the photocell according to your needs.
