Easy Lamp Flasher by IC 4011

This is Easy Lamp Flasher, I uses NAND Gates IC 4011.
Circuit is an astable multivibrator generating at 50% duty-cycle square wave about 1Hz.
The C1 - 47uF capacitors and R1 - resistors are determine the flasher rate frequency.
You must uses High current power supply for lamp only.
I use power mosfet for driver lamp because it have high power and easy than transistor.
please see part of circuit in image.
