Where low voltage supply is impractical this circuit uses a transformer-less circuit to supply power to the light detection circuit. The FK403 turns on safety, advertising, and garden lighting or security equipment at nightfall and off again at dawn. This unit is easily installed by qualified electrical personnel and uses a minute amount of mains electricity.
