I show You how to make without IC 2 modes 220 volt running light chaser with Speed controller.
Direct to AC 220 volt without additional an external DC power supply. This circuit is not using IC (Integrated Circuit), it only use 3 Transistors and a few another electronic component.
The number of Light bulbs is depending on relay current with the following simple formula:
P = V x I (P= Relays power, V=Sources voltage, I=Relays current)
Example:
If you use 1A relay on 220 volt, then the power of relay is:
220 x 1 = 220 watt
So if you use 5 watt of each light bulb, then the number of light bulbs that you can be use is:
220 watt / 5 watt = 44 light bulbs for every single relay
