These all lamps are connected in Parallel. Each lamp or Bulb is connected between Line L or P and Neutral N.
In this circuit,adding or removing one lamp has no effect on the others lamps because the Voltage in parallel circuit is same but the current is different. Any number of lamps can be added in this kind of circuit, simply by extending the L and N conductors to other lamps.

Advantages of this circuit:
- In case of break the cable or removal of any lamp will not break the all circuit, in other words, other lamps will still work.

- more size of cable wire are used in this type of wiring.
