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 electronic circuit in the SS4ED delivers extremely accurate and reliable switching control. Also includes a VDR (Voltage Dependent resistor) as standard, protecting the circuit from high transient voltages. Both the SS4D and SS4ED are available as a 'Kit' (with socket & Bracket) or a 'cell only.

The SS4 series is ideal for use in outdoor lighting systems for commerical, 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 others in the darker months and hours. The SS4 series has a number of features:

  • Helps to make outdoor areas safer and more secure in darker hours and months, with accurate light switching
  • LED Compatible
  • Provides Lux level switching for outdoor lighting systems
  • Has a detachable head for quick replacement and maintenance
  • Ideal for use in outdoor lighting schemes in areas such as: office spaces, car parks, retail spaces, public areas and more.
