The leds are fed through a rectifier in series with a .68uF capacitor connected to 120 volts. I found the same circuit on the internet except it runs off of 230 volts, www.circuitstoday.com/wp-content/uploads/2009/03/mains-operated-led-lamp.jpg
I agree too! just shows never to trust stuff you find on the internet!That circuit is not good. Not only the lack of series resistance, but there is nothing to keep the current the same in each of the 6 strings of LEDs.
the circuit still does it's job well, putting out about 60volts DC! When I drew 40mA from it, the voltage barely dropped
