Supply and not using a transformer. The circuit is using a 330nF 400V capacitor that drops the AC mains. Game rules of survival. This dropped voltage is then rectified by the 1N4007 diode bridge and filtered by the 330uF electrolytic capacitor. After filtration this voltage is steps down by the 12V zener diode and finally goes to the dark sensor circuit built with the 555 timer IC. The circuit is actually an Schmitt trigger type and it has very low input current 1.5uA.

The LDR in the circuit is used to sense the darkness. When the darkness will fall below the preset value set by the 10K variable resistor then the output of the 555 IC become high and switch ON the BT136 triac, which activates the 230V lamp.
