I was intending to run the leds via a power supply from the mains 220v. The power supply I intended using was from an external hard disk 12vdc 2a. As far as I know there's no connection with the mains other than by induction. Unfortunately I am still using a steam telephone (no camera) so I can't send a picture of the led layout. They appear to be in a series parallel layout.
