220V Dark activated switch (Photocell)
This circuit is a 110/220V AC Photocell switch (Dark activated switch) with 2 wires, it turns ON the lamps at the night and turns them OFF at the day time automatically.
The standby state power consumption in this circuit is very low, about 0.05W only,
But the commercial photocell consume about 1.6W in the standby state. (32 times more)
The circuit working with both 110V & 220V AC and the Max. load can be 4A (LED, CFL & incandescent lamps).
