This is the improved version of the LED lamp posted about 1 year ago which ran on half wave rectified dc directly from the 240 Volts mains.
As I test my projects thoroughly and want to ensure a good reliability of the project a long time 2000 hours duration run is done prior to posting the details on the web.
Again, I have choosen for the resistive option because it is more reliable than a capacitor voltage dropper.
