A breakthrough in low cost photocell technology that includes an electro-magnetic relay and a photodiode sensor that reduces burning hours, lowers power consumption and ensures lifetime switching accuracy.

The SS4 series is ideal for use in outdoor lighting systems for commercial, industrial and domestic spaces that require illumination from dusk, until dawn.  Ensuring illumination is provided only when needed, the SS4 series gives accurate switching to lighting for schools, carparks, retail spaces and other in the darker months and hours.
