led pwm controller

I am really satisfied with the manufactured pcb. It looks the same as I was designed. In a nutshell, the designed board powers 2x10W smd LED from 12V. The output is controlled by an NE555 and a IRLZ34N FET. The 4k7 potentiometer adjust the output pwm of the 555, thus indirectly control the fet's gate. The brightness can be set from a very low to a quite high level. The maximum output current is approximately 3amps at maximum pwm.
